Religiosity and Entrepreneurship Intentions among Pentecostal Christians
Authors: Abereijo Isaac Oluwajoba , Afolabi Juliana Funmilayo
Published: March 2017

Religion has been identified as an important determinant of economic behaviour because the event of enterprise creation is seen to be a consequence of the association between environmental conditions and the entrepreneurial behaviour of individuals determined by their socio-cultural background. Studies have examined how religious beliefs influence the entrepreneurial intention of the adherents, and to understand whether it is doctrine, practices, organisation or culture of religion that shapes this entrepreneurial propensity. This chapter examines the issue of religion-entrepreneurship link among the Pentecostal Christians in Nigeria and in Diaspora, by reviewing both theoretical and empirical literature. It looks at how Pentecostal theology has legitimised entrepreneurship and examines the mechanism through which is imparting entrepreneurial values and affecting patterns of thinking of the adherents. The chapter provides overview of what make them display psychological traits and attitudes consistent with entrepreneurship as a result of success-oriented theologies.
Critical Review of Entrepreneurship in Oman
Authors: Baporikar Neeta
Published: March 2017

Entrepreneurship has assumed super importance for accelerating economic growth both in developed and developing countries. It promotes capital formation and creates wealth in country. It is hope and dreams of millions of individuals around the world. It reduces unemployment and poverty and it is a pathway to prosper. The word entrepreneur is of French origin and literally means the person that takes between – the middlemen; in a more free translation, the individual who pursues a commercial activity. In spite of various studies, defining entrepreneurship is still a major dispute among researchers and the word entrepreneur still has no common meaning among the academic community. So, espousing a very broad definition for entrepreneurship that incorporates business owners and self-employed individuals and adopting a grounded theory approach with in depth literature review of published documents and data, the core of this chapter is to review critically entrepreneurship in the Middle East with specific focus on Oman.
Obiezione vostro onore. Un problematico consensus statement sull’obiezione di coscienza sanitaria / Objection your honor. A problematic consensus statement on healthcare conscientious objection
Authors: Sartea Claudio
Published: March 2017

Il saggio prende le mosse da un recente “consensus statement” elaborato da un gruppo di bioeticisti di prevalenza anglosassone ove la critica all’obiezione di coscienza è dura e sistematica. Vengono evidenziate le debolezze argomentative di questa posizione soprattutto nella prospettiva giuridica in cui l’istituto va opportunamente collocato. ---------- The essay begins from a view to a recent “consensus statement” prepared by a group of bioethicists, in prevalence Anglo-Saxon, in which the criticism to the conscientiuos objection is harsh and systematic. Argumentative weaknesses of this position are highlighted especially in the legal perspective in which the institution is appropriately placed.
The onset site of rheumatoid arthritis: the joints or the lung?

Published: March 2017

The etiopathogenesis of rheumatoid arthritis (RA) is not yet fully elucidated and the site of inflammation onset is still a matter of debate. The presence of autoantibodies as well as clinical manifestations, such as interstitial lung disease, before the onset of arthritis seems to be in favour of the hypothesis that initial pathogenic events take place in tissues other than the joint. In this review article we summarize the most recent literature on extra-synovial autoimmunity triggers eventually leading to RA, with particular focus on the role of the lung. To date, anti-cyclic citrullinated peptide antibodies (ACPAs) are considered central players in RA pathogenesis and represent the gold-standard for disease diagnosis. Lungs and mucosae are exposed to environmental stimuli such as dusts and smoke which have been shown to foster citrullination of peptides in lungs thereby triggering the production of ACPA. In addition, other mechanisms of disease pathogenesis independent of citrullination play an important role. Deeper knowledge of these processes could represent a huge step forward in the management of RA, with dramatic impact on diagnosis, prevention, prognostic stratification and treatment of the disease.
Cervical and lumbar paraspinal calcinosis in systemic sclerosis
Authors: Tan C.K. , Suresh E.
Published: March 2017

Calcinosis is a well-recognized manifestation of systemic sclerosis. Paraspinal or intraspinal calcinosis is rare, with reports of calcinosis involving the cervical, thoracic and lumbar separately, but not together. We now report a case of limited cutaneous scleroderma with extensive paraspinal calcinosis of the cervical and lumbar spine.
The impact on disability of initial treatment with methotrexate in patients with rheumatoid arthritis: results from the MARI study

Published: March 2017

The study aimed to assess in a population of subjects with rheumatoid arthritis (RA) treated with methotrexate (MTX) how the initial approach to the treatment influenced subsequent disability. We performed a cross-sectional analysis of data collected during the baseline visit of the MARI study, a multicenter observational study on patients with RA on treatment with MTX for at least 12 months. Subjects who fulfilled the Health Assessment Questionnaire (HAQ) were included in the evaluation. For every patient we retrospectively evaluated the disease duration, the duration of symptoms before the diagnosis, the time elapsed before first MTX treatment, the initial MTX dose, and the concomitant medications in the first six months of therapy. Disability was defined as a DI-HAQ score ≥1. The study population included 1015 subjects. Patients with a DI-HAQ score ≥1 had a longer duration of symptoms before diagnosis, a higher delay in treatment initiation, a lower initial dose of MTX and a more frequent co-treatment with symptomatic drugs. Disability was found less frequently in subjects treated with other concomitant disease modifying anti-rheumatic drugs (DMARDs) but not with biological agents. Logistic regression analysis identified as significant predictors of disability: older age, female sex, a longer time to complete diagnosis, a delay in starting MTX treatment higher than 6 months, and a concomitant treatment with symptomatic drugs, while a combination therapy with other DMARDs was associated with a lower risk of disability. A late diagnosis and a delay in starting a treatment with MTX are associated with poorer functional outcomes in patients with RA.
Hole CY-4 of the Cyprus crustal study project: background and objectives
Authors: Robinson P T
Published: March 2017

A 2 km drill hole (CY-4) was planned as part of the Cyrus Crustal Study Project to sample the lower part of the Troodos ophiolite. The hole was spudded in near the base of the sheeted dyke complex with the object of determining: (I) The intrusive and
compositional relationships within the dyke complex. (2) The nature of the dyke gabbro transition. (3) The age relationships of the spatially associated dykes, gabbros, and plagiogranites. (4) The chemical and mineralogical variation within the plutonic section and hence whether the intrusives are a
single magmatic sequence or a number of discrete plutons. (5) The nature and extent of hydrothermal alteration within the dykes and gabbros. It was anticipated that the drilling results, combined with field studies of the plutonic rocks and sheeted dykes, would provide a three-dimenmsional model for
the lower part of the ophiolite. Drilling was successful with 2263 m of penetration into the dyke, gabbro, and ultramafic section. Studies of the core material and the field relationships are detailed in the accompanying nineteen papers
Cyprus crustal study project hole CY-4: lithologic unit summaries
Authors: Robinson P T
Published: March 2017

Hole CY-4 is located at Lat. 34°54'06" N, Long. 33°05'380" E near the Agrokipia ore body on the north side of the Troodos ophiolite, Cyprus. The hole was drilled to a depth of 2263 m. Core recovery was 99%. More than two hundred cooling units were
identified in the field and these have been grouped into seventy nine major lithologic units. For each of these major units, the following information is given: the position and nature of the upper and lower contact, the unit thickness, the dominant lithology, and the identification numbers of the
cooling units grouped within the major lithologic unit. For each major lithologic unit, this heading is followed by a description detailing the lithology, texture, alteration mineralogy and major megascopic features.
The geology of the area immediately surrounding the CY-4 borehole of the Cyprus crustal study project
Authors: Malpas J , Case G , Moore P
Published: March 2017

Hole CY-4 of the Cyprus Crustal Study Project sampled a variety of rock types characteristic of the upper plutonic sequence of a classic ophiolite. These include a range from ultramafic to plagiogranitic lithologies which show a variety of intrusive relationships
with each other. These relationships suggest that the rocks were formed in a series of magma chambers in which differentiation processes were dominated by crystal fractionation and wall and roof rock assimilation. The action of seawater, both released into the magma by resorbtion of hydrated
diabases and gabbros, and circulating through the cooling rocks, had a major effect on the crystallisation history, alteration and chemistry of the sequence.
Sheeted dykes from CY-4 and surface sections: Troodos Ophiolite

Published: March 2017

The uppermost 600 m of the CY-4 drillhole and 10 road-cut sections provide vital data pertaining to genesis of the Troodos ophiolite. The dyke zone is prime evidence of spreading. Chilling statistics on dyke margins show little systematic bias, suggesting dyke
emplacement in a spreading zone exceeding 50 - 100 m in width. Range and distribution of dyke compositions parallel that of the lavas but lack the break in continuity, between 4-5.5% MgO, shown in glasses from pillows; a break that divides the lavas into distinctive upper and lower suites.
Equivalent suites in the dykes, identified by discriminators indicative of the upper lava suite (MgO >5.5%, Ti02 <0.85%, Cr >40 ppm) are termed the depleted and non-depleted suites respectively. Unlike their lava equivalents, dykes show no age preference as
determined by cutting relations. Much of their compositional variation can be modelled by crystal fractionation but some must be attributed to distinctive mantle sources. Accordingly, the dykes are thought to have originated at discrete, fractionating centres along the spreading axis. From each
centre they extend both vertically and longitudinally, and mutually interleave at the level of the sheeted dyke zone. Metamorphism of the dyke zone to the actinolite facies is attributed to the combined effects of heat from the underlying plutonic complex and the residual influence of marine waters
percolating from above.
Geochemical characteristics and petrogenesis of the Ophiolite sequence rocks from drill hole CY-4, Troodos complex, Cyprus
Authors: Ali H M , Nassief M O
Published: March 2017

Borehole CY-4 drilled in the southeastem part of the Troodos ophiolite sampled a sequence of diabasic, gabbroic, and mafic and ultramafic cumulate rocks. Thirteen representative samples were analyzed for major and trace elements. High Mg, Ni , and Cr contents and
low contents of Fe, Ti, alkali, and incompatible elements are characteristic features of the cumulate rocks. The first group of elements is depleted in the upper part of the section and the later group is enriched. Olivine-rich ultramafic cumulates were derived from magma in equilibrium with mantle
peridotite whereas the clinopyroxene-rich cumulates were derived from fractionated magma. Plagioclase-clinopyroxene (mafic) cumulates were probably formed from late, derivative magmas. The overall effect was a progressive lowering of Mg/Mg+Fe ratio during crystallization. The resulting magma is
represented by the gabbroic and diabasic rocks. The diabases are characterized by their low K-tholeiitic affinity and MORB/lAT setting.
In situ stress measurements and natural fracture logging in drill hole CY-4, the Troodos Ophiolite, Cyprus
Authors: Baumgartner J , Rummel F , Haimson B C , Lee M Y
Published: March 2017

Hydraulic fracturing stress measurements were conducted in the upper open-hole segment of drillhole CY-4 (0-600 m). Based on the results of some twenty hydraulic fracture orientations two stress fields were discerned, one near the surface (50-200 m depth) and
apparently strongly affected by local topographic relief, and another at 200-600 m. The latter stress field was calculated using two different data analysis methods. Based on conventional calculations the state of stress in the range of 200-600 m is given by Sv = 0.28 bar/m x depth (m), Sh = 12 +
0.16 bar/m x depth (m) at N22°W, SH = 7 + 0.25 bar/m x depth (m) at N68°E (where Sv is the vertical stress, SH is the major horizontal stress, and sh is the minor horizontal stress). Using the Ps-technique, the state of stress in the 200-600 m zone is given by: Sv = 0.28 bar/m x depth (m),
Sh = 0.17 bar/m x depth (m) at Nl 1°W, SH = -6 + 0.28 bar/m x depth (m) at N79°E. The two methods of interpretation yielded similar values for both magnitudes and direction of principal stresses. A borehole sonic televiewer (BHTV) was used to log natural fractures crossing the hole wall.
The BHTV logging revealed a state of densely spaced natural fractures of varying inclinations and orientations, dominated by two steeply dipping sets. Also detected on the borehole wall were several segments of spalling (breakouts) which appear to be associated with zones of closely spaced natural
fractures.
A gravity survey from Agrokipia to Papoutsa, Cyprus
Authors: Kramvis S , Verosub K L
Published: March 2017

We report the results of a gravity survey designed to provide a geophysical connection between holes CY-2a and CY-4 of the Cyprus Crustal Drilling Project. The survey consists of 93 stations on a 22.5 km line from Agrokipia to Papoutsa. The observed value of
gravity at each station is determined from the datum in Nicosia previously used for an extensive gravity survey of the island. In the present survey, free air, simple Bouguer and complete Bouguer anomalies are reported for reduction densities of 2.50 and 2.67 gm/cc. For a reduction density of 2.50
gm/cc, the complete Bouguer anomaly reaches a maximum value of 195 mgal about one-third of the way from Agrokipia and Papoutsa with values of 185 and 178 at these two locations, respectively.
Post-Glacial Paleo-Oceanography, Northeast Newfoundland Shelf
Authors: Miller A A L , Scott D B , Smith D
Published: March 2017

Forty-five sediment samples from three sediment cores (one trigger weight, two piston) from the northeast Newfoundland Shelf were analyzed for benthfc and planktonic foraminifera, pollen and dinoflagellates. Five benthic foraminiferal faunas were found in cores
07TWC and 07P (combined), four post-glacial and one glacial. These five assemblages are (down core): an agglutinated (Inner Labrador Current - late Holocene) assemblage; a N. labradorica (Outer Labrador Current· - mid-Holocene) assemblage, a M. barleeanum - Pullenia spp. ("cold" Labrador
Current - early Holocene) assemblage; an L. helenae - C. reniforme - C. laevigata ("warm" Labrador Current - early Holocene/late Pleistocene) fauna and an E. excavatum - C. reniforme ("warm" glacial ice-margin - late Pleistocene) fauna. Only two faunas were found in core 015P; the agglutinated
assemblage and the "warm" ice-margin assemblage which directly overlies till or till - like material barren of foraminifera. If the post-glacial sequence in cores 07TWC and 07P is complete, then most of the post-glacial sedimentary record (2500-10000 YBP) is missing from core 015P. The planktonic
foraminifera present with the agglutinated benthic fauna in core 015P indicates there has been mixing of Gulf Stream and Inner Labrador Current surface waters during the late Holocene, at this site.

The Wire Protection Program was implemented to improve oceanographic cable maintenance procedures at the Bedford Institute of Oceanography. These maintenance procedures can be easily justified when one realizes the lasses of equipment and data which can occur in
the event of rope failure. Three phases have been carried out ta date: Part 1Criteria For Lubricant Selection Part 2 Testing of Lubrication Equipment Part 3 Lubricant Analysis. The first phase involves the identification of wire rope lubricants suitable for testing, and determines through a
literature review and correspondence with users what properties are required ta produce a good field dressing. In Part 2, lubrication equipment was tested, and in Part 3, tests were carried out in the lab and in the field which compared lubricant properties and formed the basis for a
conclusion.
Duration Magnitudes For Nahanni Earthquakes Recorded By Field Networks, October 1985, January 1986, September 1986
Authors: Wetmiller R J , Plouffe M
Published: March 2017

Since the two large earthquakes in the Nahanni area, in October and December 1985, three field surveys have been conducted. In the last one, in September 1986, nearly 200 aftershocks were located. Using the permanent Fort Simpson station, magnitudes of only 26
larger events could be determined. Magnitudes of 309 smaller events were calculated using their signal duration on the analog field stations. Two programs, discussed here, were used in this calculation. One organizes the calibration events. The other one, with an inverse matrix calculation, finds a
best-fit magnitude duration equation. For the third Nahanni survey, an equation:
MC= -0.42 + 1.72*log(CL) + 0.01*D
where CL is the coda-length and D the hypocentral distance of the events, is proposed to define the relationship between signal
duration and magnitude. The same type of equation was used to find duration magnitudes for the two other surveys. Magnitudes were assigned to 347 events from the October 1985 survey and 239 events from the January 1986 survey. The magnitudes determined will be used to calculate the
magnitude-frequency properties of the aftershock activity.

Earthquake activity and the operation of digital seismograph stations in south-eastern Canada during the one-year period from July 01, 1989 to June 30, 1990 are described. The Geophysics Division of the Geological Survey of Canada operated a network of 19
telemetered seismograph stations (ECT:\' ) from eastern New Brunswick to eastern Ontario as well as two autonamous local telemetered networks: one in the Charlevoix region of Québec (CLTN: six 3-component stations) and the other in the Sudbury region of Ontario (SLTN: three single-component
stations). The Division also operated a network of 19 strong-motion accelerographs centred around the Charlevoix region of Québec. Analysis of the seismic data was carried out in the earthquake datalab at the Geophysics Division in Ottawa using dual PDP 11/73 computers for acquisition, a VAX
11/750 computer for archiving, a MicroVAX II computer for seismicity analysis and display and a SUN 4/280 computer as a database server. In the area covered by the report there were 234 earthquakes documented, 23 were magnitude 3.0 or greater. Eighteen of the earthquakes were reported felt. The
largest event onshore in southeastern Canada was a magnitude 4.0 event in western Québec, north of Ottawa, on November 16, 1989. The first surface fault break from an earthquake in Canada was found in extreme northern Québec by a Geophysics Division field party in July, 1990. The 5.5 km
surface rupture was caused by a magnitude 6.2 earthquake on December 25, 1989.
U-Pb zircon constraints on the timing and provenance of fluvial sedimentary rocks in the Flin Flon and Athapapuskow basins, Flin Flon Domain, Trans-Hudson Orogen, Manitoba and Saskatchewan
Authors: Ansdell K M
Published: March 2017

Fluvial sedimentary rocks of the Missi Group in the Paleoproterozoic Flin Flon Domain, Manitoba and Saskatchewan, which unconformably overlie Amisk island-arc and ocean-floor volcanic rocks, were likely deposited in basins that developed as a result of crustal
thickening during early arc-continent collisions in the Trans-Hudson Orogen. U-Pb analyses of detrital zircons from the Flin Flon and Athapapuskow basins, yielded ages that tightly constrain the timing of sedimentation, and provide information on the age of the source region. The Flin Flon Basin is
intruded by Boundary Intrusions, with a published U-Pb age of 1842 +/- 3 Ma. The youngest detrital zircon has a concordant U-Pb age of 1847 +/- 2 Ma, indicating that Missi sedimentation in the Flin Flon Basin occurred between 1847 and 1842 Ma. U-Pb ages of 1848 +/- 2 and 1846 +/- 6 Ma yielded by
zircons from the Athapapuskow Basin suggests that sedimentation in the two basins was likely synchronous. The range in zircon ages suggests that much of the detritus was derived locally from granitoids and Amisk volcanic rocks. However, 207Pb/206Pb zircon ages of 2431, 2473, and 2494 Ma from the
Flin Flon Basin, and 2708 and 2721 Ma from the Athapapuskow Basin indicate that Early Paleoproterozoic/Archean terranes were exposed at the time of Missi Formation sedimentation.
U-Pb age for the Jurassic McEwan Creek pluton, north-central British Columbia: regional setting and implications for the Toarcian stage boundary
Authors: Evenchick C A , McNicoll V J
Published: March 2017

The McEwan Creek pluton in northwest Stikinia is part of the Late Triassic to early Middle Jurassic magmatic belt around the northern Bowser Basin. Fossiliferous Lower to mid-Toarcian country rock provide an oldest age for the pluton. A U-Pb age of 183.5 +/- 0.5
Ma for the McEwan Creek pluton corroborates the intrusive relationships, and indicates that the Early to mid-Toarcian must be 184 Ma or older, an important refinement of the Jurassic time scale.
U-Pb ages for Late Cretaceous and early Tertiary plutons in the Skeena Fold Belt, north-central British Columbia
Authors: Evenchick C A , McNicoll V J
Published: March 2017

The Poison and Motase plutons, in southeast Bowser Lake and south McConnell Creek map areas respectively, are post-tectonic with respect to local contractional structures of the Skeena Fold Belt. A U-Pb age of 84.1 +/- 0.5 Ma for the Poison pluton establishes
that some of the deformation in the central fold belt occurred prior to Late Cretaceous time. A U-Pb age of 55.4 +/- 0.2 Ma for the Motase pluton indicates that it, and probably two nearby, similar plutons, are Eocene in age rather than Late Cretaceous, and that local contractional structures are
pre-Eocene in age.

Geology of Paul Lake area, Lac de Gras-Lac du Sauvage region of the central Slave Province, District of Mackenzie, Northwest Territories
Authors: Kjarsgaard B A , Wyllie R J S
Published: March 2017

The Lac de Gras area of the Northwest Territories is currently the focus of intense exploration activity for diamondiferous kimberlite intrusions. The geology is dominated by Archean metagreywacke and granitoids. Ductile deformation has produced at least two sets
of folds and related fabrics. Granitoid emplacement occurs syn- and post-tectonically. Faulting occurred during the Late Archean/Early Proterozoic. Four Proterozoic dyke swarms cut the Archean rocks in the map area. Detailed structural data were obtained for the area, along with subdivisions of the
granitoid suites represented and new information on contact relationships. Possible controls on the spatial emplacement of kimberlites are considered in relation to regional structures and Proterozoic dyke swarms.
Contact relationships between the Anialik River volcanic belt and the Kangguyak gneiss belt, northwestern Slave Province, Northwest Territories
Authors: Relf C , Chouinard A , Sandeman H , Villeneuve M E
Published: March 2017

Mapping in the northwest part of the Hepburn Island map area examined a major fault separating the ca. 2.69 Ga Anialik River volcanic belt from ca. 3.1 Ga gneissic tectonites of the Kangguyak gneiss belt. Evidence for at least two periods of displacement along
the fault were observed; early movement is marked by a 200 m wide zone of straight gneisses recrystallized under amphibolite facies conditions, and later movement is marked by a narrower zone (less than 10 m) of chlorite schist containing quartz veins, local C-S fabrics, and breccia zones. Kinematic
indicators associated with the later displacement record oblique (dextral) west-over-east movement. Early movement is more ambiguous, but a steep lineation associated with the straight gneisses implies predominantly dip-slip movement. Contrasting ages, bulk compositions, deformation histories, and
metamorphic grades across the fault suggest that the Kangguyak gneisses and the Anialik River volcanic belt represent two distinct terranes.
Geology and mineral occurrences of the central part of High Lake greenstone belt, Archean Slave Province, Northwest Territories: a preliminary account of an unconformity between two volcanic sequences
Authors: Henderson J R , Henderson M N , Kerswill J A
Published: March 2017

Supracrustal rocks in the central part of the High Lake belt are interpreted to comprise an intermediate to felsic sequence of volcanic and volcaniclastic rocks that is unconformably overlain by a mafic to felsic sequence of volcanic, volcaniclastic, and
sedimentary rocks. The area contains many gossans, and numerous base and precious metal occurrences, including the synvolcanic polymetallic mineralization at High Lake which is tentatively assigned to the older sequence. Metamorphism is chlorite grade, and locally abundant cordierite in felsic
volcanic rocks of the older sequence possibly resulted from synvolcanic hydrothermal alteration. The older sequence predates the earliest deformation (D1). In the younger sequence, earliest structures (D2) are upright subhorizontal folds that apparently strike at a large angle to the dominant
northerly trend of the belt; these are overprinted by a north-northeasterly trending vertical foliation and steeply-plunging folds (D3). Granitoid batholiths surround the belt, and are late syn- to post-D3.
Preliminary report on the geology of the Indin Lake supracrustal belt, western Slave Province, Northwest Territories
Authors: Pehrsson S J , Beaumont-Smith C
Published: March 2017

Preliminary study of the Indin Lake area has identified two spatially restricted turbidite units; one coarser bedded containing felsic volcanogenic debris flows and a finer unit with iron-formation. They are intercalated with spatially separated volcanic belts
characterized by mafic pillowed volcanic rocks or intermediate to felsic volcaniclastic rocks. Four main structural sets have been recognized. The first set includes isoclinal folds without associated cleavage and foliations parallel to the volcanic belt contacts. The second set which controls the
geometry of the belt includes a cleavage axial planar to meso- to macro-scale folds, and interference folds. The remaining sets are more locally developed. Repetition of the intercalated units is in part a function of third phase or later regional refolding. The supracrustal belt is in contact with
a heterogeneously deformed granodiorite-tonalite igneous complex to the east. Deformation of the complex is pre-intrusion of hornblende-biotite-granodiorite plutons.
Disseminated gold mineralization in the Stewart River area, La Ronge Domain, Saskatchewan
Authors: Poulsen K H , Robert F
Published: March 2017

Disseminated gold mineralization in the Stewart River area occurs in sillimanite-bearing, quartzofeldspathic gneisses, derived from conglomerate, arenite, and minor tuff, and cut by monzodiorite dykes and younger pegmatite bodies. Zones of disseminated native
gold occur mainly within more extensive lenses of quartz-feldspar-muscovite schist that contain less than 5% disseminated pyrrhotite and pyrite and traces of chalcopyrite, molybdenite, sphalerite, and galena. The lenses are approximately parallel to the regional strike of their host rocks, but,
in detail, are discordant to primary lithological contacts. The para-concordant nature of the predeformational and premetamorphic sulphide bodies is the result of their transposition parallel to a strong northwest dipping S1 foliation, axial planar to a reclined intrafolial F1 anticline. The host
rocks were further folded to occupy the overturned northwest limb of a southward-closing, reclined regional F2 fold.
Structural investigation of high-grade rocks of the Kramanituar complex, Baker Lake area, Northwest Territories
Authors: Sanborn-Barrie M
Published: March 2017

The Kramanituar complex comprises granulite-grade gabbro, gabbroic anorthosite, and paragneiss and is hosted by amphibolite-grade plutonic and supracrustal wall rock. Its northern boundary coincides with a granulite-grade shear zone, 60 km long and up to 6 km
wide, across which sinistral, south-side-up displacement is recorded. Its southern boundary appears to coincide with an amphibolite-grade shear zone, 30 km long and up to 2 km wide, across which dextral, north-side-up movement has occurred. Preliminary observations suggest that the complex
represents a high-grade, crustal-scale tectonic lens, or boudin, which was rapidly exhumed during noncoaxial, southwest-directed shortening.
Archean and Lower Proterozoic geology of western Dubawnt Lake, Northwest Territories
Authors: Peterson T D , Born P
Published: March 2017

The bedrock of western Dubawnt Lake consists of: (1) Archean, migmatized metasedimentary rocks comprised mainly of biotite-quartz-feldspar-garnet schist, including sulphide iron-formation; (2) a mafic-to-felsic intrusive suite (the Snow Island suite), dominated
by granites (2605 Ma), which accompanied the migmatization; and (3) orthoquartzite plus minor schists assigned to the Lower Proterozoic Amer Group. A pervasive, shallowly south-southwest-plunging extension lineation (L2) developed at upper greenschist facies during thrusting (D2) which involved the
Amer Group and older basement rocks. L2 was folded (D3) by east-west-trending folds. D2 and D3 must predate brittle deformation at 1.84 Ga leading to Dubawnt Supergroup deposition, during the Trans-Hudson orogeny. Deformation of the Amer Group probably accompanied the east-west collision between the
Slave and Churchill cratons at 2.0-1.9 Ga.
Geology of Archean and Proterozoic supracrustal rocks in the Otter and Ducker lakes area, southern District of Keewatin, Northwest Territories
Authors: Aspler L B , Chiarenzelli J R , Ozarko D L , Powis K B
Published: March 2017

The local stratigraphy of the Archean Henik Group, part of the Ennadai-Rankin greenstone belt, consists of a siliciclastic turbidite sequence and a sequence of interlayered mafic and felsic volcanic rocks with magnetite iron-formation-bearing turbidites. Both
sequences are intruded by Archean granitic plutons. Early Proterozoic Hurwitz Group granulestone, subarkose and quartz arenite (Kinga Formation) were deposited in fluvial, eolian and lacustrine environments in a radially expanding intracontinental basin developed on Archean basement. The abrupt
appearance of mudstone and arkose (Ameto Formation) is attributed to sudden basin deepening and marine flooding. Upper Hurwitz Group strata define an offlap sequence including a carbonate ramp (Watterson Formation), local lagoons (Ducker Formation semi-pelites) and a coastal facies (Tavani Formation
subarkose with evaporite-bearing dolostone). Map patterns are controlled by the interference between basement-involved northwest- and east-trending D1 folds and antithetic thrusts and northeast- and north-trending D2 folds.
Transition between the Flin Flon and Kisseynew domains of the Trans-Hudson Orogen, File Lake-Limestone Point Lake area, northern Manitoba
Authors: Connors K A , Ansdell K M
Published: March 2017

The tectonothermal evolution of the File Lake-Limestone Point Lake area, which includes part of both the Flin Flon and Kisseynew domains of the Trans-Hudson Orogen, involved early bedding parallel faulting, two generations of isoclinal folds (F1, F2), and two
generations of upright folds (F3, F4). Prograde metamorphism occurred syn- or post-F1 and peaked post-F1/S1, pre-S2. Metamorphic conditions remained sufficient for biotite recrystallization during F4. Map units and early isoclinal folds can be traced from greenschist grade rocks to uppermost
amphibolite grade gneisses. S1 and S2 vary progressively from near vertical in greenschist to amphibolite grade rocks to gently dipping in upper amphibolite gneisses. This transition from steep to shallow structures with increasing metamorphic grade may reflect: i)changing rheology; ii)increasing
shear strain; and/or iii) a buttress effect at the northern margin of the Flin Flon Domain.
Geological, geochemical, and age constraints on base metal mineralization in the Manitouwadge greenstone belt, northwest Ontario
Authors: Zaleski E , Peterson V L , van Breemen O
Published: March 2017

The Cu-Zn deposits of the Manitouwadge greenstone belt lie within an upper amphibolite-facies, highly deformed remnant of supracrustal rocks adjacent to the Wawa-Quetico subprovince boundary. In the primary depositional setting, two independent and geochemically
distinct, coeval volcanic centres (circa 2720 Ma) erupted calc-alkaline felsic rocks onto a substratum of tholeiitic shield basalt. Metasedimentary rocks were deposited in a basin between the volcanic centres. The northern felsic domain, associated with extensive synvolcanic alteration, subvolcanic
intrusion and iron-formations, hosts massive sulphide mineralization including the Geco mine. Original relationships were modified during D1 and D2 thrust imbrication and folding. The regional structure of the belt is dominated by the D3 Manitouwadge synform, interpreted to be a refolded fold.
Metamorphic grade increases continuously across the Wawa-Quetico boundary, but peak conditions developed later in the Quetico subprovince (2670 to 2650Ma) than in the Manitouwadge belt (2675 Ma).
Structure and tectonics of the Manitouwadge greenstone belt and Wawa-Quetico subprovince boundary, Superior Province, northwestern Ontario
Authors: Peterson V L , Zaleski E
Published: March 2017

We propose a revised structural geometry and deformation history for the Manitouwadge greenstone belt of the northern Wawa subprovince adjacent to the Quetico subprovince. Early folding and thrusting with a possible sinistral component produced D1 and D2
structures. The dominant D2 foliation and lineation were produced during peak metamorphism. The Manitouwadge synform resulted from D3 deformation, possibly progressive from D2, following peak metamorphism. Dextral oblique shear during D4, possibly synchronous with migmatization in the Quetico
subprovince, produced broad to focussed shear strain and refolded the Manitouwadge synform. Evidence for refolding, based on detailed mapping and aeromagnetic interpretation, is suggested by northeastward extension of the 'Geco horizon' through a series of folds. D5 structures reflect continued
dextral oblique shear, focussed along the Wawa-Quetico boundary. The Manitouwadge belt and its mineral deposits appear to have shared a common structural history with the adjacent Quetico subprovince since D2/D3.
Geology of the Levack gneiss complex, the northern footwall of the Sudbury structure, Ontario
Authors: Card K D
Published: March 2017

Rocks of the Archean Levack gneiss complex that underlie the northern part of the Sudbury Structure comprise supracrustal and intrusive units that were deformed and metamorphosed under granulite facies conditions in the lower crust during the Archean. They were
intruded by late Archean granite of the Cartier batholith and uplifted, either during the late Archean or early Proterozoic, by tectonic or impact processes. They were strongly affected by the shock and thermal metamorphism associated with the Sudbury impact event and probably contributed
significantly to the formation of the Sudbury igneous complex and its ores. Structures imaged by seismic reflection profiles in the area are attributed to thrusts or deformation zones that are part of a regional system of south-dipping structures that cut and displace the Sudbury
structure.
Vein fields in gold districts: the example of Val d'Or, southeastern Abitibi subprovince, Quebec
Authors: Robert F
Published: March 2017

Among abundant vein-type gold deposits in the Val d'Or district, quartz-tourmaline-carbonate veins are singled out as having a remarkable uniformity of hydrothermal and structural characteristics over an area 40 x 15 km. These veins are undeformed and are younger
than other types of veins in the district. Quartz-tourmaline-carbonate veins are interpreted to be the product of a single, large hydrothermal system and to define a vein field. The recognition of at least two ages of veins and of the existence of a large vein field at Val d'Or has important
implications for the understanding of the origin of these deposits and for their exploration.
Sphenothallus angustifolius Hall, 1847 from the lower upper ordovician of Ontario and Quebec
Authors: Bolton T E
Published: March 2017

A well preserved cluster of Sphenothallus angustifolius Hall, 1847 is illustrated from the Edenian-Maysvillian Collingwood Formation exposed at Bowmanville, Ontario. The genus ranges from early Ordovician to Permian. The species is now recognized in the lower
Upper Ordovician black shales of the Lake St. John region, Québec, the St. Lawrence and Ottawa Lowlands, north-central New York State, the Bowmanville, Collingwood-Craigleith and eastern Manitoulin Island regions of southern Ontario, and the Upper Peninsula of Michigan. It includes a number of
taxa originally assigned to Serpulites. Its phylogenetic affinity, cnidarian (conularid) or annelid, is still debatable. The new examples display a carbonate-apatite laminar test or 'skin', fine transverse ridges, and a primary flatness between angulate margins, but with no indication of the tubular
or quadrate cross-section characteristic of worm tubes or conularids.
Partie II: analyse économique
Authors: Waghmare R R , Dallaire S M , Conn R F
Published: March 2017

Part II consists of an economic analysis of the undiscovered Triassic natural gas resources. Estimates are made of the relation between the plant-gate price of natural gas and the volume of economically recoverable undiscovered resources. Supply curves are
presented, with and without a fiscal burden, for full-cycle and half-cycle cases, and for a weighted case, which is an average of the full- and half-cycle results. The weighted case is regarded as the reference case in this study. In the weighted case, 106 m3 per cent of the volume of recoverable
gas is estimated to be economic at a price of $44.13 per 103 m3 ($1.25 per MCF), and 38 per cent at a price of $88.25 per 103 m3 ($2.50 per MCF). Prices are expressed in 1990 dollars. These percentages correspond to 8 per cent and 30 per cent, respectively, of the undiscovered initial gas-in-place
volumes estimated in Part I. Estimates of the volume of economic gas potential for the entire Triassic (established and conceptual plays) are 25 x 109 m3 (0.9 TCF) and 92 x109 m3 (3.3 TCF) at the two prices. Further analysis shows the sensitivities of economic potential to changes in total costs,
exploration success ratios, distances of discoveries to gathering systems, and resource estimates. Virtually all of the economically recoverable gas resources in the Triassic are found in four plays: the Halfway/Doig Shelf-Monias, Baldonnel Subcrop-Laprise, Halfway/Doig Shelf-Tommy Lakes, and
Halfway/Doig Shore-Sinclair.
A potassic phreatomagmatic volcanic centre in the Thelon Basin (Northwest Territories): implications for diamond exploration
Authors: Peterson T D
Published: March 2017

An exposure of the strongly potassic and magnesian Kuungmi Formation (less than 1.72 Ga) within the Thelon Basin has the characteristics of a phreatomagmatic volcanic centre, including vesicular sandy tuffs and phlogopite-rich accretionary lapilli. This centre
demonstrates that the geological conditions which permit development of diamondiferous lamproite vents were present in the early to mid-Proterozoic, when the Thelon Formation was much more extensive.
Geology and structure of the Barbour Bay region, District of Keewatin, Northwest Territories, and its potential for industrial garnets
Authors: Tella S , Mader U , Schau M
Published: March 2017

Archean supracrustal rocks in the Barbour Bay region form a northeast-trending, synformal remnant within a granitoid gneiss terrane. They are composed of a conformable sequence of mafic metavolcanic rocks and semipelitic schists that are deformed and
metamorphosed under amphibolite facies conditions. The semipelitic rocks contain garnet±biotite±cordierite±sillimanite+plagioclase+quartz assemblages. Interlayers of garnetite with up to 80% garnet porphyroblasts, and sillimanite-rich layers are common within the schists. They
reflect highly Al- and Fe-rich compositions of a metasedimentary protolith. P-T estimates for metamorphism are in the order of 2.8-3.6 kb and 520°C-650°C. The garnetite layers appear to offer a potential source of industrial garnets. The garnets occur in three forms (idiomorphic glassy,
idiomorphic dull, poikiloblastic), and contain 70-90 mol% almandine, 5-12 mol% pyrope, and 2-8 mol% grossular. Further work is necessary to determine the grade, tonnage, milling and separation characteristics, abrasive quality of different garnet-types, and the commercial viability of
the potential deposit.
Thematic structural studies in the Slave Province: preliminary results and implications for the Yellowknife Domain, Northwest Territories
Authors: Bleeker W , Beaumont-Smith C
Published: March 2017

Preliminary results indicate that the structure of the area is dominated by two phases of regional folding that produce mushroom-type interference patterns. The Sleepy Dragon Complex is such a regional-scale interference structure. Its geometry and timing of
formation contradict the hypothesis that the complex represents a core complex. They also cast doubt on previous kinematic studies. F2 folding was a response to dextral transpression during which both the Defeat Suite and Prosperous Suite granitoids were emplaced. Regional low-pressure metamorphism
is largely late-D2 and associated with granitoid emplacement. Following F2 folding, D2 dextral transpression became localized in discrete dextral shear zones that record retrograde metamorphism.
Archean unconformity in the Qalluviartuuq greenstone belt, Goudalie domain, northern Quebec
Authors: Winsky P A , Kusky T M , Percival J A , Skulski T
Published: March 2017

An unconformity in the northern Qalluviartuuq greenstone belt separates basement of metasedimentary and tonalitic rocks from conglomerate and sandstone. The basal conglomerate has tonalitic clasts, grading upward into a polymict assemblage of tonalite, basalt,
andesite, granodiorite, metasedimentary and ultramafic clasts. The basalt, gabbro, and ultramafic clasts suggest that a metavolcanic terrane was being eroded in the (local) source area for the conglomerate, and yet the conglomerate passes with apparent stratigraphic continuity upwards into mafic
volcanics. Either an older greenstone sequence within the basement complex contributed detritus to the conglomerate, or a tectonic break may be hidden in the complex structure of a fragmental mafic unit marking the contact between the conglomerate and metavolcanic units. In this second hypothesis,
an overriding greenstone sheet would have shed clasts as it was thrust over synorogenic conglomerate deposited on basement.
Oxide iron-formation-hosted lode gold, Meliadine Trend, Rankin Inlet Group, Churchill Province, Northwest Territories
Authors: Miller A R , Balog M J , Tella S
Published: March 2017

Oxide iron-formation in the ca 2.66 Ga lower- to middle-greenschist facies Rankin Inlet Group defines a pronounced discontinuous 65 km long northwest-trending aeromagnetic linear, the Meliadine Trend. Quartz+carbonate veined iron-formation is host to lode gold
prospects that are spatially associated with a 1-2 km wide ductile to brittle high strain zone. Two types of lode gold are recognized based on: 1)regional and local lithological variations, 2) type of oxide iron-formation, 3) deformation style, 4)differences in silicate-carbonate-sulphide
assemblages, and 5) gold compositions. A Proterozoic hydrothermal event is indicated by Ar-Ar and Pb-Pb isotopic ages from silicate and sulphide alteration minerals. Widespread Proterozoic thermotectonism in the eastern Churchill Province reactivated pre-existing Archean shear zones during the early
Proterozoic. Hydrothermal fluids channeled along these structures are postulated to have formed Proterozoic lode gold deposits in Archean rocks.
Lamprophyre dykes of the Christopher Island Formation, Thirty Mile Lake, District of Keewatin, Northwest Territories
Authors: Jones A L , Miller A R , Armitage A E , MacRae N D
Published: March 2017

The Thirty Mile Lake area is underlain by upper amphibolite to granulite grade para- and orthogneiss and by Archean megacrystic alkali feldspar megacrystic granite. Paleoproterozoic gabbro, lamprophyre, and feldspar porphyry dykes intrude basement rocks. A thick
hematitic saprolite was developed in the gneiss prior to deposition of South Channel Formation sharpstone conglomerate. The lamprophyre dykes, equated to the Christopher Island Formation of the Baker Lake Group, are of two types. The first contains phlogopite phenocrysts in a groundmass consisting
of phlogopite, alkali feldspar, and apatite; the second contains phlogopite±amphibole in a groundmass consisting of amphibole, alkali feldspar, and apatite. The lamprophyre dykes intrude along a northwest-trending joint set and east-trending mylonite zones. Oblate xenoliths of granitoid and
less abundant mafic-ultramafic compositions occur in the dykes; some xenoliths display recessive rims indicating reactions with the host rock. The lamprophyres are being thoroughly studied in order to evaluate their diamond potential.
