Entrepreneurship and Innovation
Authors: Gonçalves Maria Ortelinda Barros , Remoaldo Paula Cristina , da Cunha Paulo J. A. , Silva Nair
Published: March 2017

For countries like Portugal, with limited prospects in terms of employment, one of the solutions involves emigration and the desire of part of the Portuguese people to establish enterprises in other countries, England being one of the most favoured. Taking into account these premises, and in the scope of a broader research on the Portuguese Emigrant Entrepreneurship in Andorra, London, Nice and Monaco, we carried out a questionnaire to 51 Portuguese entrepreneurs living in London, within several economic sectors, between 2013 and 2014. Our main goals were to know the profile of Portuguese immigrant entrepreneurs in London, the reasons for their emigration, the need or opportunity for entrepreneurship, the types and areas of activity of their businesses, the obstacles they had to deal with and the possibility for them to return to Portugal. The novelty of our research lies in the study of the ethnic and economic emigration of Portuguese emigrants in London, a study that was under-researched and under-analysed to this date.
Social Entrepreneurship and Social Innovation in Southeast Asia and its Role on Development
Authors: De Sousa Miguel Rocha , Docuyanan Mary Ann
Published: March 2017

This chapter provides five comprehensive cases of social entrepreneurship and innovation in Southeast Asia and its role on development. We start from a theoretical innovation model based on differential inclusions mathematical theory which is new to the innovation literature. Afterwards we cross-examine the theory with the empirical cases. Main conclusions refer that the differential inclusion model can eventually refer to a more general framework, but nevertheless the five cases are very relevant to specify the use of the model.

This paper makes a foray into the new innovative business technologies by presenting several important aspects of the Digital Economy, Business models, Entrepreneurship, Information and Communication Technologies (ICT), ICT4D, Innovation Technology. The second part of the paper consists of an analysis of new innovative technologies results in business, using Global Entrepreneurship Monitor (GEM), thus presenting the conceptual framework GEM, How GEM Defines Entrepreneurship, Measures of Entrepreneurial Activity, Entrepreneurial Aspirations, Entrepreneurial Attitudes. Based on this analysis, empirical results of new innovative business technologies in Romania are configured, highlighting the key indicators for Romania (2015), Entrepreneurial Activity rates in efficiency-driven EU Countries in 2014 (% of population aged between 18-64 years), distribution of entrepreneurs by gender, age, education and household income in Romania 2014 (%), both individually and overall. The paper concludes with key findings and proposals for the following questions to be explored in future research.
Impact of Information Technologies, Corporate Entrepreneurship and Innovation on the Organizational Performance
Authors: Pinho Cláudia Sofia B. , Ferreira João J.
Published: March 2017

Information Technology (IT) capabilities play a fundamental role on process innovation and organizational performance. Likewise, corporate entrepreneurship (CE) plays a vital role in the improvement of performance, as the employees' profile is determinant for the success of these organizations. Previous literature relating to IT and CE reveals how little attention has been paid to relationship between these constructs, and what exists is only partial. This research conceptualizes the relationship between IT capabilities, CE, and innovation on the organizational performance. It is intended as a contribution to the ongoing conceptual development of this area and provides initial guidance for future empirical evidence. Thus, the authors advance a synthesized conceptual model in order to evaluate the influence of IT capabilities (IT flexibility, IT integration and IT alignment) to the CE process, through innovation on the organizational performance. The authors create an initial construction of the scenery grounded in past literature, which is refined and reinforced into a conceptual model advancing in theoretical development in the field. Some future research and implications are discussed.
L’educazione sessuale nelle scuole: analisi critica sul piano etico e giuridico di alcune proposte dell’OMS / Scholar sex education: critical analysis of some WHO’s proposals from an ethical and legal point of view
Authors: Nepi Leonardo
Published: March 2017

Si va consolidando il consenso sull’importanza dell’educazione sessuale rivolta a giovani e fanciulli, anche attraverso la previsione di specifici programmi educativi nelle scuole, ma il dibattito sui contenuti dell’educazione sessuale stessa rimane acceso. Si confrontano infatti diverse impostazioni, fondate su diverse concezioni della sessualità. Affrontando il tema da una prospettiva etico-giuridica, di particolare interesse risulta l’analisi del documento proposto dall’Ufficio regionale per l’Europa dell’OMS (Standard per l’educazione sessuale in Europa), che nell’affrontare la questione fa riferimento a controverse categorie, che meritano un adeguato approfondimento. Questo contributo intende allora evidenziare l’equivocità di alcuni concetti (salute sessuale e riproduttiva, diritti sessuali e riproduttivi, violenza di genere) utilizzati nel documento dell’OMS, per mettere in luce le implicazioni che un’adesione acritica a queste proposte comporterebbe. ---------- There is growing consensus on the importance of sexuality education, also through the provision of specific programs in schools aimed at young people and children, but the debate on it is still in progress, because of different educational settings based on diverse concepts of sexuality. Addressing the issue from an ethical and legal perspective, particularly interesting is the analysis of the document proposed by the WHO Regional Office for Europe (Standards for Sexuality Education in Europe), for its reliance on controversial models, which deserves thorough examination. This paper will highlight the ambiguity of some concepts (sexual and reproductive health, sexual and reproductive rights, gender based violence) used in the WHO document, in order to emphasize the implications of an uncritical adherence to these proposals.
Structural and petrologic relationships of the CY-4 drill hole of the Cyprus crustal study project
Authors: Malpas J , Brace T , Dunsworth S M
Published: March 2017

Hole CY-4 of the Cyprus Crustal Study Project was intended to sample the plutonic complex of the Troodos ophiolite from the base of the sheeted dykes down to mantle tectonites. Accompanying the drilling programme was an intensive field mapping project which
together with the results from drilling was aimed at elucidating the complex magmatic and structural history of a fossil crustal accretion zone and the relationships between the plutonic series and the extrusive volcanic carapace of the ophiolite. The recognition of an older series of deformed
plutonic rocks intruded by a series of undeformed cumulate rocks is the most significant evidence supporting the model of multiple magma chambers at the spreading axis. Geochemical evidence from from the CY-4 borehole supports the structural relationships and indicates that the borehole intersected
two separate magma bodies which can be related to the major geochemical subdivisions of the pillow lava sequence.
Igneous mineral stratigraphy and chemistry of the Cyprus crustal study project drill core in the plutonic sequences of the Troodos Ophiolite
Authors: Thy P , Schiffman P , Moores S M
Published: March 2017

The CY-4 drillhole of the Cyprus Crustal Study Project penetrated dykes, gabbros, and ultramafic cumulates of the Troodos ophiolite near Palekhori. Above 640 m, the borehole section consists mainly of finegrained, granular, two-pyroxene dykes. From 640 to 1330 m,
dykes become progressively less common and medium-grained, olivine-free, two-pyroxene gabbros gradually dominate. The contact at 1330 m is intrusive. The younger sequence from 1330 to 1754 m, consists of gabbroic cumulates containing plagioclase (An90_86) and pyroxenes with Ti contents comparable to
those of the dyke, but with higher Mg-numbers. The section from 1754 to 2263 m comprises relatively coarse-grained websteritic cumulates with plagioclase (An>95) and the pyroxenes characterized by very low-Ti and high-Cr contents. The Fo mol.%, An mol.%, and Mg-numbers of cumulus
phases generally decreases upward in the core. The lower cumulate complex probably formed in a slow- or non-spreading environment. In contrast the upper cumulate complex reflects a relatively faster spreading environment. The results of the present investigation suggest that the central ultramafic
cumulates of the Troodos ophiolite did not form in a large, steady-state, frequently replenished, axial magma chamber (Abstract abbreviated by the editors without the authors'consent).
A chelation-solvent extraction method for analysis of dissolved manganese in marine sediment pore waters by flameless atomic absorption spectroscopy
Authors: Hughes S E , Buckley D E
Published: March 2017

A chelation-solvent extraction method using 8-Hydroxyquinoline ("oxine") and methylisobutyl ketone (MIBK) was developed for analysis of dissolved Mn in pore waters by flameless atomic absorption spectroscopy. The extraction requires 2 ml of pore water sample, and
the method can measure concentrations in the 0 to 50 ppb range. Samples with greater Mn concentrations are diluted. Results obtained by the solvent extraction method agree to within 15% of those obtained by flame atomic absorption. Dilution of concentrations greater than 1 ppm to less than 50
ppb introduced increased analytical error and did not yield results superior to those given by flame atomic absorption.
The extraction method is recommended for samples containing Mn concentrations less than approximately 1 ppm because of its lower detection limit (approximately 6 ppb). Use of the flame atomic absorption method is recommended for samples containing more then 1 ppm Mn (detection limit 200
ppb).
Surficial geology of the upper Scotian Slope west of Verrill Canyon
Authors: Piper D J W , Wilson E
Published: March 2017

Piston cores and high-resolution seismic-reflection profiles have been studied from an area 50 x 50 km square on the Scotian Slope, west of Verrill Canyon, in water depths of 200 to 1000 m. Apart from Verrill Canyon, no major valleys incise the slope in this
area. Sand and gravel extend from the continental shelf to water depths of 400-500 m. Below this a series of shallow gullies ( 200-500 m wide, 5-25 m deep) lead to two large debris flows in water depths of 500-1000 m. The flows are 5-15 ms thick in seismic-reflection profiles, and there is another
horizon of debris flows visible about 50 ms subbottom. Otherwise, slope sediment is acoustically well stratified and draped over topographic irregularities. Piston cores have been collected from both the debris flows and undisturbed sediment sequences between the flows. Four lithostratigraphic units
are recognized in the undisturbed section. A carbon-14 date of 12,000 years B.P. has been obtained near the base of this sequence, and is consistent with the palynological and foraminiferal stratigraphies. The debris flows are overlain by a thin sediment sequence, and are estimated to date from
between 5000 and 12,000 B.P.
Geochemical data from analyses of surface sediments obtained from Halifax Inlet
Authors: Buckley D E , Hargrave B T , Mudroch P
Published: March 2017

Geochemical data are compiled from analyses of surficial sediment samples collected from the marine area of Halifax Inlet in 1986 and 1988. In 1986 Prouse and Hargrave collected Van Veen grab samples from 102 stations at water depths greater than 10 m on a grid
from the mouth of the Sackville River to Maugher's Beach Lighthouse. Similarly, in 1988 the OceanChem Group collected Van Veen grab samples from 135 stations in Halifax Inlet.
Sediment analyses included grain size, porosity (water content), total carbon, organic carbon, caco3 and total metals (Si, Al, Ca, Mg, K, Ti, Fe, Mn, Cu, Zn, Ni, Pb, Hg and Li) Redox potential (Eh) of the sediments was also measured at the time of sampling.
Pore water analyses were conducted to measure dissolved carbon dioxide gas.
Coal Geology of the Battle River Coalfield, East - Central Alberta
Authors: Dawson F M , Cameron A R , Jerzykiewicz T
Published: March 2017

Coal within the Battle River coalfield is Late Cretaceous in age and belongs to the Horseshoe Canyon Formation. Ten coal zones spanning a stratigraphie interval of approximately 150 m have been correlated within the study area. The coal zones are commonly split
into numerous plys with individual coal seam thicknesses up to 2.0 m observed. Total zone thicknesses up to 6.0 m are present in the subsurface. Of the ten recognizable coal horizons, the Paintearth and Battle-River are the most laterally consistent and economically significant. Total in-situ
resources are estimated at 9 512 megatonnes, to a maximum depth of 150 m. Resources are primarily derived from two coal zones, the Battle-River and Paintearth, with minor contributions from three lesser zones. Mineable coal resources at less than 5:1 hem/tonne overburden ratio total 392 megatonnes,
of which the Paintearth zone accounts for 200 megatonnes. Coal resources for the Battle River coalfield were calculated in 1987. Detailed resource numbers conforming to the newly released Coal Association standards are available through the National Coal Inventory of the Geological Survey of Canada.
Currently, two open pit coal mines are in operation within the Battle River coalfield, producing in excess of 1.5 megatonnes annually for the Alberta Power generating station at Battle River. Ash values for the Paintearth and Battle-River coal zones range from 8 to 29 percent, with the Battle-River
zone generally having a lower range. The coals are of subbituminous C and B rank with calorific values ranging from 20.1 to 24.0 MJ /kg. Sulphur values are low ranging from 0.32 to 0.74 percent for the Paintearth zone and from 0.47 to 1.19 percent for the Battle-River zone. The high sulphur values
for the latter appear to be anomalous and are located at the southern end of the study area. Petrographic studies suggest that the coals of the Battle-River coalfield were deposited within a lower delta plain environment. This agrees for the most part with sedimentological observations throughout
the project region.
Monazite age of 1747 Ma confirms post-Penokean age for the Eden Lake complex, southern Province, Ontario
Authors: Sullivan R W , Davidson A
Published: March 2017

A concordant U-Pb monazite age of 1747 +/- 3 Ma is reported for the crystallization and emplacement of the Eden Lake pluton. This age is in the same post-Penokean age range as previously dated plutons in the Southern Province.
Geochronological studies in the Flin Flon Domain, Manitoba-Saskatchewan, NATMAP Shield Margin Project area: results for 1992-1993
Authors: Stern R A , Lucas S B , Syme E C , Bailes A H , Thomas D
J , Leclair A D , Hulbert L
Published: March 2017

Eight new U-Pb zircon ages are reported for volcanic and plutonic rocks from the Paleoproterozoic Flin Flon Domain. The shoshonitic Vick Lake tuff crystallized at 1885 +/- 3 Ma, marking a late phase of arc-related volcanism. Synvolcanic diabase of the Ocean Floor
Assemblage at Athapapuskow Lake is poorly dated at ca. 1.9 Ga, but nevertheless is the first direct age constraint on mafic rocks of the Ocean Floor Assemblage. Tonalite from the West Arm of Athapapuskow Lake crystallized at 1903 +6/-4 Ma, an age that supports a correlation with the dated Mystic
Lake tonalite to the northwest, places a minimum age on the volcanic rocks it intrudes, and a maximum age for its deformation. Porphyritic granodiorite and marginal gabbro from the Reynard Lake pluton crystallized at 1850 +/- 3 Ma and 1849 +3/-2 Ma, respectively. As the pluton is larely undeformed,
these results place a minimum age on an early foliation that we attribute to amalgamation of the Ocean Floor, Mystic Lake, and Arc assemblages. A felsic dyke, interpreted as having intruded during terrane amalgamation, crystallized at 1869 +/- 1 Ma. Thus, deformation associated with terrane
accretion commenced after 1903 Ma, was in progress by 1869 Ma, and was complete by 1850 Ma. Amphibolite-facies quartz diorite from the sub-Paleozoic Namew Gneiss Complex crystallized at 1880 +/- 2 Ma. An improved age of 1831 +5/-4 Ma was obtained for the Cormorant Batholith, marking the last major
phase of plutonism in the Flin Flon Domain.
40Ar-39Ar geochronology of selected crystalline basement samples from the Alberta Basin: the timing of Proterozoic assembly of the subsurface of western Canada
Authors: Plint H E , Ross G M
Published: March 2017

On the basis of U-Pb geochronology and potential field interpretations, the crystalline basement of Alberta is interpreted to record the collisional assembly of crustal fragments during the interval 1.99-1.78 Ga and possibly as far back as 2.2 Ga. In order to
further refine existing tectonic models, hornblende and muscovite were separated from selected basement drill core to determine 40Ar/39Ar cooling ages. Hornblende from an Archean amphibolite in the Eyehill High, a high-grade metamorphic block within the Hearne Province along the Alberta-Saskatchewan
border, gave a plateau age of 1796 +/- 11 Ma. This age is interpreted to record cooling from a high-grade metamorphic overprint coeval with orogenic activity in the adjacent Trans-Hudson Orogen. A lower amphibolite grade metabasite collected immediately west in the Loverna Block of the Hearne
Province, gave a highly disturbed and inconclusive age spectrum. Hornblende from a ca. 2.3 Ga quartz diorite in the Thorsby Low, the subsurface extension of the Snowbird Tectonic Zone, yielded a disturbed spectrum with an apparent age in the high-temperature step of 2102 +/- 13 Ma. Hornblende from a
coarse metagabbro in the Chinchaga Domain, one of several continental slivers in northern Alberta that were accreted to the Rae Province between 1.99 and 1.90 Ga, gave a well defined plateau age of 1934 +/- 12 Ma. We infer the age to reflect cooling from thermal effects associated with accretion.
Similar results have been reported for U-Pb analyses of titanite. In the northern Buffalo Head Domain, a muscovite from a pegmatite that cuts a metasedimentary schist gave a plateau age of 1882 +/- 12 Ma, which we attribute to postaccretionary cooling. A muscovite from a metarhyolite in the Nova
Domain gave a plateau age of 1722 +/- 11Ma. This domain is a sliver of Archean gneisses with a Paleoproterozoic cover sequence that sits astride the Hay River fault zone, the subsurface extension of the McDonald fault. The muscovite cooling age is similar to Rb-Sr cooling ages reported from the
southern Thelon Front and is interpreted to record cooling associated with uplift and continental indentation.
U-Pb and 40Ar-39Ar geochronology of plutonic rocks from the Teslin suture zone, Yukon Territory
Authors: Stevens R A , Mortensen J K , Hunt P A
Published: March 2017

An isotopic dating study was undertaken in the Teslin suture zone of south-central Yukon in order to constrain; 1) the protolith ages of rock units that took part in Teslin suture deformation and, 2) the timing of deformation and uplift of Teslin suture zone
rocks. Three bodies of deformed metatonalite to quartz diorite from the study area give Early Mississippian U-Pb zircon ages. These are interpreted as crystallization ages and provide a minimum depositional age for siliciclastic metasedimentary units that they intrude. A massive hornblende-bearing
tonalite to quartz diorite pluton gives Early Jurassic U-Pb zircon (÷188 Ma), 40Ar/39Ar biotite (182 +/- 2 Ma), and 40Ar/39Ar hornblende (179 +/- 2 Ma) ages. The U-Pb zircon age is interpreted as a minimum crystallization age and places a local minimum age for deformation of Teslin suture zone rocks
in the study area. The 40Ar/39Ar ages are interpreted as uplift/cooling ages and are younger than previously reported cooling ages (184-195 Ma) for rocks of the zone.
New U-Pb dates from southwestern Coast Belt, British Columbia
Authors: Monger J W H , McNicoll V J
Published: March 2017

Four new U-Pb dates of granitic rocks from the southwestern Coast Belt are reported. The Bodega Point pluton on Quadra Island, Bute Inlet map-area (92K), is the westernmost Coast Belt pluton at this latitude and intrudes Wrangellian stratigraphy; it has been
dated at 163.8 +/- 0.4 Ma, Middle Jurassic. To the northeast, along Bute Inlet, two samples were analyzed from a region of granitic rocks previously mapped as mostly of Cretaceous age. The Paradise River pluton, at 145 +/- 2 Ma, is latest Jurassic, similar in age to the Cloudburst quartz diorite in
Vancouver map area (92G). The Ward Point pluton is 153.6 +/- 0.4 Ma, Late Jurassic; this age is comparable to others in southwestern Coast Belt. Granodiorite on Mount Roderick, apparently part of a regionally extensive composite body herein called the Howe Sound batholith, yields a mid-Cretaceous
age of 95.8 +/- 1 Ma. This date places a maximum age on contractional deformation on the Britannia shear zone near Howe Sound, and falls within the period spanned by regional deformation in the southeastern Coast Belt.
Regional geology of the Winter Lake-Lac de Gras area, central Slave Province, District of Mackenzie, Northwest Territories
Authors: Thompson P H , Ross D , Davidson A
Published: March 2017

In the Winter Lake-Lac de Gras area, narrow belts of metavolcanic rocks occur between a northeastern metasedimentary domain and a southwestern migmatitic, gneissic granitoid domain containing subordinate supracrustal rocks. Homogeneous late plutons intrude both
domains. Supracrustal rocks are assigned to the Yellowknife Supergroup. Complex fold interference patterns in the metasedimentary domain contrast with subrhombic geometry outlined by thin supracrustal belts surrounding large blocks of metagranitoid and gneiss. Lowest grade of low pressure regional
metamorphism in supracrustal rocks is associated with migmatitic, foliated granitoid and gneiss. The lithological transition and differences in structure and metamorphic grade are attributed to a higher proportion of pre-Yellowknife sialic crust to the southwest. Base metal and gold deposits occur
within the metasedimentary domain and volcanic rocks. Supracrustal rocks are less mineralized where they are subordinate to pre-Yellowknife rocks. Diamondiferous kimberlites occur just east of the area in the metasedimentary domain.
The sedimentology and provenance of the Et-Then Group as a record of deformation on the McDonald fault zone, East Arm, Great Slave Lake, Northwest Territories
Authors: Ritts B D
Published: March 2017

The Proterozoic Et-Then Group of the East Arm of Great Slave Lake, is a sequence of non-marine clastic rocks and minor basaltic volcanics with a maximum thickness of at least 4000 m. The alluvial fan conglomerates of the older Murky Formation fine gradationally
into the braided fluvial sandstones of the younger Preble Formation. Physical relationships between Et-Then Group strata and structures related to the McDonald fault system indicate that Et-Then Group sedimentation was concurrent with deformation on that system. Stratigraphic relationships, sediment
provenance and facies proximality show that Et-Then Group sedimentary rocks are a direct result, and record the history of deformation associated with the McDonald fault. Description and interpretation of the sedimentology, depositional systems, and three-dimensional lithostratigraphy of the Et-Then
Group are used to suggest possible models for tectonic, climatic and/or source rock controls on Et-Then sedimentation.
Lithological and structural relationships in Paleoproterozoic rocks in the east Wekusko Lake area, Trans-Hudson Orogen, Manitoba
Authors: Ansdell K M , Connors K A
Published: March 2017

Distinct lithological packages, largely fault-bounded, have been defined east of Wekusko Lake in the Flin Flon Domain, Trans-Hudson Orogen. Packages of sedimentary rocks include the File Lake formation turbidites and two packages of Missi Group sandstones and
conglomerates. The packages of volcanic rocks include the North Roberts Lake mafic volcanics, the Herb Lake fold rhyolites, andesites and basalts, a heterogeneous package of felsic volcanic rocks, and the McCafferty Liftover mafic to intermediate lavas and tuffs. The main stage of deformation
involved isoclinal F2 folding, and associated faulting which resulted in juxtaposition of lithological packages. Metamorphism occurred during this stage of deformation. Local preservation of an older cleavage indicates an earlier phase of deformation (D1) which may have been responsible for initial
thickening and tectonic burial. F2 folds and associated faults are overprinted by F3 folds which postdate peak metamorphism and may represent the terminal stages of this event.
Glacial dispersal and drift composition, Rice Lake Greenstone Belt, southeastern Manitoba
Authors: Henderson P J
Published: March 2017

Quaternary geology mapping and till sampling in the Rice Lake Greenstone Belt is oriented toward understanding the major factors influencing mineral exploration using drift prospecting. These factors include: the nature of glacial dispersal, bedrock composition,
and the extent of postglacial weathering. Ice flow indicators and patterns of glacial dispersal of clasts from known sources indicate the area was glaciated predominantly by ice flowing southwest during the last glaciation. Near Lake Winnipeg, the striation record is more complex. Older striae
indicate ice flow toward the south-southwest, southeast, and south, although relative ages are unclear. Trace element concentrations in the <0.063 mm fraction of till reflect bedrock composition, and anomalous gold values are directly related to known occurrences or zones of gold
mineralization. In vertical profiles, variations in trace element values show patterns related to postglacial weathering. These effects are minimized at depths over 0.6 m, which suggests the zone below may provide the most consistent sample medium.
Oceanic allochthons in an Archean continental margin sequence, Vizien greenstone belt, northern Quebec
Authors: Skulski T , Percival J A , Stern R A
Published: March 2017

The Vizien belt comprises tectonic panels of mature arc rocks, a continental rift sequence, and an oceanic allochthon. The 2.724 Ga arc sequence contains mafic to felsic calc-alkaline lavas and metasediments. The <2.718 Ga rift package comprises
metasediments which rest unconformably on 2.9 Ga tonalite, overlain by mafic to felsic tholeiitic lavas. The allochthonous oceanic panel is floored by mélange or serpentinite, and comprises peridotite/gabbro sills intruded into submarine basalts and sediments. The arc lavas are LREE-enriched
with eNd of +0.50; rift lavas have higher LREE abundances and lower Nd (0.33 to -0.47); whereas oceanic peridotite sills (to Fo87) have REE contents and eNd values (1.34 to 2.94) reflecting depleted mantle derivation. Early marine sediments in the Vizien arc sequence indicate an island arc setting.
Later marginal basin formation may have produced juvenile oceanic crust. Subsequent orogeny involved oceanic crustal obduction, basement-cored nappe emplacement, isoclinal folding, high-T metamorphism, late folding and faulting.
Combining field observations and remote sensing to map the Grenville Front along the Pascagama River, Quebec
Authors: Graham D F , Ciesielski A
Published: March 2017

A remote sensing analysis of part of the Grenville Front is presented, following previous work east of Val d'Or, Quebec using ground geology, satellite imagery and magnetic data to reveal the front. In the study area, 110 km east of Senneterre, Quebec, Landsat
and magnetic data were supplemented with data from a new ERS-1 satellite imaging radar which is sensitive to terrain topography and surface roughness. The data were enhanced using contrast stretch, directional and median filtering, shaded relief and the IHS (Intensity, Hue and Saturation) transform.
The Grenville Front was located using structural trends based on field observations and coinciding with the boundaries of magnetic anomalies, linear waterways and lineaments enhanced on TM and ERS-1 radar data. The position of the Front was extrapolated in unmapped and till covered areas using
magnetic contrasts of the vertical gradient data.
Preliminary geological investigation of the Lake Harbour Group and surrounding gneissic rocks near Lake Harbour and Markham Bay, southern Baffin Island, Northwest Territories
Authors: Scott D J , Godin L
Published: March 2017

Preliminary examination of Paleoproterozoic siliciclastic and carbonate supracrustal rocks of the Lake Harbour Group and surrounding tonalitic gneisses was undertaken in two small areas south and west of Iqaluit. North of Lake Harbour, the Lake Harbour Group
consists of siliciclastic schists, marble, and calcsilicate schists preserved in a tight synform surrounded by younger granitoid rocks. At Markham Bay, similar supracrustal rocks grade into migmatitic rocks. Preliminary U-Pb geochronological results from the Lake Harbour area suggest that
penetrative deformation of the Lake Harbour Group occurred prior to, or during, peak metamorphic conditions at ca. 1845-1840 Ma. Folding of the S1 fabric, possibly synchronous with emplacement of the adjacent tonalitic rocks, occurred ca. 1840-1830 Ma. The age of monazite from an undeformed granitic
dyke, 1760 ± 2 Ma, brackets the time of final regional tectonic activity.
A reconnaissance of the high grade metamorphic terrane south of Ghost Lake, southwestern Slave Province, Northwest Territories
Authors: Henderson J B , Chacko T
Published: March 2017

A series of isolated fixed wing landings were made throughout much of an 80 km long by up to 35 km wide, triangular shaped, high metamorphic grade terrane that is outlined by a prominent aeromagnetic signature. It is underlain by Archean granitoid gneisses,
massive to foliated plutons, and migmatitic to diatexitic supracrustal rocks of the Yellowknife Supergroup. Granulite grade mineral assemblages occur throughout most of the northern, east-central and south-central parts of the terrane. Megascopic orthopyroxene was not observed in the high grade
rocks in a zone along the southwestern part. The terrane is fault bounded and has been interpreted as an asymmetric block uplift with most displacement taking place along a major low grade cataclastic shear zone on the east side of the uplift. The maximum age of uplift of the block is interpreted to
be 2.1 Ga.
Geology, geochronology, and metallogeny of High Lake greenstone belt, Archean Slave Structural Province, Northwest Territories
Authors: Henderson J R , Kerswill J A , Henderson M N , Villeneuve M , Petch C A , Dehls J F , OKeefe M D
Published: March 2017

High Lake greenstone belt, mapped along strike for 100 km, is subdivided into three domains based on lithological association, results of U-Pb zircon dating of volcanic rocks, and distribution of mineral occurrences. The oldest volcanic rocks (ca. 2.70 Ga) are
felsic and predominate in the Western domain. Younger basaltic, andesitic, and dacitic flows and tuffs (ca. 2.67 Ga) are observed in the Eastern domain. The youngest rock interpreted to be volcanic, mapped in the Central domain, is a dacite (ca. 2.62 Ga) at the contact between greywacke and
graphitic-sulphidic slate and siltstone. The belt is surrounded and intruded by 2.62-2.58 Ga granitic plutons and batholiths. In the Western and Eastern domains, synvolcanic massive sulphides occur in intermediate to felsic volcanic rocks. In the Western domain, zones of hydrothermal alteration
("dalmatianite") are indicated by porphyroblastic knots of quartz-sericite-chlorite or cordierite. In the Central domain, epigenetic gold occurs with arsenopyrite-quartz in dilatant zones in mafic volcanic as well as metasedimentary rocks.
Granitoid plutons and major structures in the Iskwasum Lake sheet, Manitoba: a portion of the Flin Flon Domain of the Trans-Hudson Orogen
Authors: Morrison D W , Whalen J B
Published: March 2017

Six major granitoid plutons intrude mafic volcanic rocks, mafic tectonites and older plutonic rocks within the Iskwasum Lake sheet of Manitoba (NTS 63K/10). Three of these plutons are contiguous with plutons of the adjoining Elbow Lake sheet, which range in age
from 1.876 Ga to 1.826 Ga, and in composition from granodiorite to quartz diorite. The Iskwasum Lake sheet is structurally complex, containing four major shear zones and many minor faults. Except for the late east-west-trending Berry Creek fault in the south, most of these structures are apparently
early and long-lived, north-northeast-trending structures. Based on geochemical studies of correlative volcanic assemblages bounding these structures to the north, some probably represent important internal boundaries or sutures within the Flin Flon Domain of the Paleoproterozoic Trans-Hudson
Orogen.
The geological framework of groundwater in the Greater Vancouver area
Authors: Ricketts B D , Liebscher H
Published: March 2017

Groundwater in the Vancouver, Fraser Valley and adjoining Coast and Cascade mountain area flows through three main types of material: (1) unconsolidated or semiconsolidated sediment of glacial and interglacial origin in the Fraser Valley and delta, which is less
than 2 million years and mainly less than 100 000 years old; the sand and gravel aquifers generally have high porosity (up to 40% and high hydraulic conductivity; (2) lithified Cretaceous and Tertiary sedimentary rocks, which have low intergranular porosity (<15%) and some
fracture porosity; and (3) fractured granitic and metamorphosed sedimentary and volcanic rocks mostly greater than 90 million years old in the Coast and Cascade mountains. The greatest demand for groundwater, comprising more than 44% of water requirements in the Fraser Valley, is from
Quaternary deposits and in particular the Sumas Drift (10 000-14 000 BP), which includes the unconfined Abbotsford and Brookswood aquifers. Water quality in some of these aquifers is already compromised by human activities. A sound knowledge of the hydrogeological properties of these, and the many
confined aquifers in the region, is critical if expedient and cost effective remediation programs are to be developed.

Field evidence for the character of the Precambrian rocks south of the Rockland Brook fault, Bass River block, Cobequid Highlands, Nova Scotia
Authors: Pe-Piper G , Piper D J W , Koukouvelas I
Published: March 2017

Field and petrographic studies, confirmed by published geochronology, show that the southern part of the "Great Village River gneiss" consists of deformed Gamble Brook Formation and Neoproterozoic plutonic rocks and the northern part comprises mylonitized
earliest Carboniferous plutonic rocks. The gneiss does not represent an arc root, but rather high-level plutons deformed in a Neoproterozoic shear zone. The sequence of plutonic rocks in the Bass River block is similar to that in southern Cape Breton Island and the Caledonia
Highlands.
Preliminary results from reprocessing of seismic reflection data in the Cumberland Basin, Nova Scotia
Authors: Marillier F , Durling P
Published: March 2017

Industry seismic reflection data collected in 1972 in the Late Devonian to Permian Cumberland Basin have been reprocessed using modern techniques. Major improvements in data quality were achieved and the range of recoverable data was extended from four to five
seconds. Several reprocessed seismic sections are shown. A section through the Malagash Anticline reveals its internal structure and suggests that salt flowage was associated with faulting. Another section indicates that the surface-defined Beckwith Fault extends to depth where it offsets near-base
Windsor Group reflections by about one second. Finally, a section located near the Wallace Station No. 1 well links seismic data to the well, although it does not provide a rigorous tie. The section and synthetic seismograms suggest that, contrary to what was previously interpreted, the well did not
reach Horton Group rocks, but rather bottomed above that unit in middle Windsor Group rocks.
A tale of shale-stratigraphic problems in the Gander River map area, Newfoundland
Authors: Currie K L
Published: March 2017

The ophiolitic Gander River Complex is imbricated with sedimentary cover of diverse derivations (Davidsville Group, Weirs Pond Formation) to record major shortening in post-Caradoc to pre-Llandovery time, contemporaneous to thrusting of the Hamilton Sound Group
(volcanics plus Caradoc black shale and chert) over Davidsville Group. The Davidsville Group forms a turbiditic, fining-upward sequence without volcanic component emplaced on a continental slope or rise. The Indian Islands Group, a marine shelf assemblage unconformably overlying the Hamilton Sound
and Davidsville groups, spans much of Silurian time. The Duder Complex, basement to the region between the Reach Fault and Dog Bay Line, forms an accretionary prism of early Silurian age in which blocks cannot be readily correlated with surrounding units. Redbeds of the Ludlow or younger Ten Mile
Lake Formation postdate the Botwood Group, which is absent east of the Reach Fault.
Particle size analysis of fine grained Champlain Sea sediments from a borehole near Ottawa, Ontario
Authors: Traynor J A
Published: March 2017

Grain size distributions of postglacial sediments from a continuously sampled borehole in the Mer Bleu bog, east of Ottawa, were determined using the Brinkman particle size analyzer of the Mineral Tracing and Sedimentology Laboratory, Terrain Sciences Division.
Forty of fifty samples were thought to be deposited in a marine environment. Clay-sized material (<0.002 mm) ranged from 13 per cent to 49 per cent and averaged 30 per cent, and a fining-upward trend was noted. The relatively small amount of clay in the samples is consistent with emerging
delta front and delta top environments of deposition described by others, but the regional significance of the fining-upward trend is unknown. The similarity in grain-size distribution of sediment in samples from a more distal part of the basin to the Mer Bleu samples suggests that proximity to the
basin centre is not the only factor influencing the clay-sized content of marine sediments.
Northeastern North American earthquake potential - new challenges for seismic hazard mapping
Authors: Adams J , Basham P W , Halchuk S
Published: March 2017

Most previous seismic hazard maps for eastern Canada and the United States were essentially based on a model that assumes a continuation of the historical pattern and rate of seismicity. New evidence from global studies of earthquakes in stable continental
regions has shown that most of the larger earthquakes occur through reactivation of relatively young (<500 Ma) rift faults that break the integrity of the continental crust. Thus, current seismicity associated with those structures suggests that future large earthquakes in northeastern
North America may occur elsewhere on the same structures, even on the historically-quiet portions. The impact of such geological associations on the hazard estimates depends critically on the sizes of the zones, and the relative weights that are given to "geological" and "historical" earthquake
source zones in the hazard model. We suggest here a "robust" approach, using the highest hazard from several plausible models, and argue that its non-probabilistic basis represents an acceptable compromise.

In 1994, high resolution aeromagnetic surveys totalling 103 446 line km were flown in three areas of Manitoba and Saskatchewan. These surveys were partially funded by industry and (for the Saskatchewan portion) by the Canada-Saskatchewan Partnership Agreement on
Mineral Development (1990-1995). A detailed gradiometer survey totalling 12 573 line km was flown in Nova Scotia and funded by the Canada-Nova Scotia Cooperation Agreement on Mineral Development (1992-1995). An airborne electromagnetic/magnetic survey totalling 13730 line km was flown in the
Chibougamau greenstone belt of Quebec funded under the Special Assistance Program for the Mining Sector of the Chapais-Chibougamau Region (1992-1995). The program to level the Canadian aeromagnetic profile dataset to eliminate the effect of survey boundaries was completed for the Northwest
Territories and eastern Alberta. Drape computation and levelling of the British Columbia surveys is in progress. Six thousand line kilometres of high-resolution aeromagnetic data have been flown west of Banks Island by the Institute for Aerospace Research, National Research Council, as part of the
Polar Margin Aeromagnetic Program.
National gravity survey program of the Geological Survey of Canada, 1994-1995
Authors: Hearty D B , Gibb R A
Published: March 2017

Seven gravity surveys were completed under the national gravity survey program in 1994: two were reconnaissance surveys located in Coronation Gulf and Dease Strait in the Arctic and west of the Queen Charlotte Islands; three were detail gravity surveys near
Bolton, Ontario, near New Glasgow, Nova Scotia, and in the St Lawrence River near La Malbaie, Quebec; and two were gravity control network surveys in Nova Scotia and on Ellesmere Island and Greenland in the high Arctic. Approximately 2123 new gravity stations and 5100 line kilometres of dynamic
gravity observations were collected on these surveys. These data will be added to the National Gravity Database. In addition, Canada participated in the fourth International Comparison of Absolute Gravimeters in Sèvres, France and made absolute gravity measurements at one site in Manitoba and
eleven sites in British Columbia in support of the GSC's crustal dynamics program.
Baculites compressus robinsoni Cobban from the Crowsnest River section at Lundbreck, Alberta: an implication for the timing of the late Cretaceous Bearpaw transgression into the southern Foothills of Alberta
Authors: Jerzykiewicz T
Published: March 2017

The occurrence of Baculites compressus robinsoni Cobban in the Bearpaw shale near Lundbreck, Alberta, indicates that during the time of the Baculites compressus Zone (i.e., at approximately 73.4Ma), the Bearpaw marine transgression extended into the area now
occupied by the Rocky Mountain Foothills. At that time, the Bearpaw transgression attained its maximum extent and covered both the southern plains and Rocky Mountain Foothills, and probably extended as far west as the footwall of the Lewis Thrust. The record of Bearpaw deposition in the southern
Foothills is correlative with that of the southern plains. It consists of a lower shaly part, and an upper sandy part containing regressive, eastward prograding shelf-shoreface cycles, below the contact with the Blood Reserve Formation.
Petrophysical characteristics of diatreme-facies kimberlites from Kirkland Lake, Ontario
Authors: Katsube T J , McClenaghan M B , Scromeda N
Published: March 2017

Electrical resistivity (rho-r), effective porosity (phi-E) and bulk density (delta-B) have been measured on nine diatreme-facies kimberlite samples and six limestone samples from the Kirkland Lake area. One purpose of this study is to provide data required for
interpretation of surface and airborne geophysical survey data. Another purpose is to determine if physical characteristics can distinguish between limestone xenoliths contained in these kimberlites and the source rock of the xenoliths.

Results indicate that the values for delta-B (2.3-2.5 g/mL), phi-E (13-25%) and rho-r (30-470 Ohm-m) for these kimberlites are generally within the reported range for Canadian kimberlites, and are similar to those of the crater facies kimberlites. This implies relatively low delta-B and rho-r,
and relatively high phi-E values. The values of delta-B (2.2-2.8g/mL), phi-E (4-22%) and rho-r (30-1.2x104 Ohm-m) for the limestones are generally within the reported range. The only limestone xenolith measured displays the largest phi-E and smallest rho-r values among the
limestones.

Ice and snow are part of the Canadian psyche, and naturally Canadians are leaders in scientific research in this field. This video looks at some intriguing research under way, including work conducted from a huge slab of ice adrift in the Arctic Ocean not far
from the North Pole, and the extraction of ice cores whose geological records provide us with the key to the Earth's past.
Contrasting styles of deformation and metamorphism between mid and upper crustal rocks of the western Slave Province, Northwest Territories
Authors: Pehrsson S J , Chacko T
Published: March 2017

The Indin Lake and Grenville Lake supracrustal belts record a polyphase deformation history. F1 isoclinal folding was followed by F2 tight folding and cleavage development coeval with regional low-pressure/high-temperature metamorphism. Open, northeast-trending
F3 folds overprint earlier structures. Complexities in structural geometry of volcanic rocks may reflect early imbrication and/or folding, prior to south-vergent, F1 folding. Peak conditions of low-pressure/high-temperature metamorphism are estimated at 3.5 kbar and 575þC.

The Grenville and Snare Lake þgneiss' domains comprise para- and orthogneiss, amphibolite and granitoid intrusions, that underwent higher grade metamorphism (6-7 kbar, 650-800þC). Regional structures are characterized by upright, open F3 folds of a shallowly-dipping foliation.

Decompression textures and oblique-normal faulting between and within the supracrustal belts and gneiss domains, together point to juxtaposition of the upper and mid-crustal rocks during regional extension.
Lithostratigraphy and metallogenic implications of komatiite - banded iron-formation - felsic volcanic rocks of the Archean Woodburn Lake group, Pipedream Lake, central Churchill Province, Northwest Territories
Authors: Kjarsgaard B A , Kerswill J A , Jenner G A
Published: March 2017

Detailed mapping, stratigraphic investigations, and metallogenic studies of rocks belonging to the Woodburn Lake group were initiated in the vicinity of Pipedream lake. Field relationships suggest the following stratigraphic sequence of rock types (from oldest to
youngest): quartzite, komatiite suite, intermediate/felsic volcaniclastic and epiclastic rocks including iron-formation, siliciclastic sedimentary rocks. The intermediate to felsic volcaniclastic and associated epiclastic rocks host a newly discovered massive sulphide showing, several styles of
vein-type gold, plus numerous occurrences of sulphide-bearing iron-formation. Evidence to date suggests that the massive sulphide, polymetallic vein gold, and possibly the pyrrhotite-rich sulphide-bearing iron-formation are directly linked to synvolcanic/synsedimentary processes. Mineral deposit
types observed (i.e. massive sulphide; polymetallic gold; sulphide iron- formation; distal komatiite flow facies with poor potential for Ni mineralization) are consistent with combined lithostratigraphic/volcanological/paleoenvironmental interpretation.
