Authors: Al-Hamdan N. , Saeed A. , Kutbi A. , Choudhry A. J. , Nooh R.
Published: January 2011

Objective. To determine the prevalence, risk factors, characteristics, and treatment practices of known adult hypertensives in Saudi Arabia.Methods. Cross-sectional community-based study using the WHO stepwise approach. Saudi adults were randomly chosen from Primary Health Care Centers catchment areas. Data was collected using a questionnaire which included sociodemographic data, history of hypertension, risk factors, treatment practices, biochemical and anthropometric measurements. Collected data was cheeked, computer fed, and analysed using SPSS V17.Results. Out of 4719 subjects (99.2% response), 542 (11.5%) subjects were known hypertensives or detected by health workers in the past 12 months. Hypertension was significantly associated with age, gender, geographical location, education, employment, diabetes, physical inactivity, excess body weight, and ever smoking. Multiple logistic analysis controlling for age showed that significant predictors of hypertension were diabetes mellitus, ever smoking, obesity, and hypercholesteremia. Several treatment modalities and practices were significantly associated with gender, age, education, and occupation. About 74% were under prescribed treatment by physicians, 62% on dietary modification, 37% attempted weight reduction, 27% performed physical exercise, and less than 7% used herbs, consulted traditional healers or quitted smoking. Income was not significantly associated with any treatment modality or patient practices.Conclusion. Hypertension (known and undetected) is a major chronic health problem among adults in Saudi Arabia. Many patients' practices need changes. A comprehensive approach is needed to prevent, early detect, and control the disease targeting, the risk factors, and predictors identified.
Translating Research into Clinical Scale Manufacturing of Mesenchymal Stromal Cells
Authors: Bieback Karen , Kinzebach Sven , Karagianni Marianna
Published: January 2011

It sounds simple to obtain sufficient numbers of cells derived from fetal or adult human tissues, isolate and/or expand the stem cells, and then transplant an appropriate number of these cells into the patient at the correct location. However, translating basic research into routine therapies is a complex multistep process which necessitates product regulation. The challenge relates to managing the expected therapeutic benefits with the potential risks and to balance the fast move to clinical trials with time-consuming cautious risk assessment. This paper will focus on the definition of mesenchymal stromal cells (MSCs), and challenges and achievements in the manufacturing process enabling their use in clinical studies. It will allude to different cellular sources, special capacities of MSCs, but also to current regulations, with a special focus on accessory material of human or animal origin, like media supplements. As cellular integrity and purity, formulation and lot release testing of the final product, validation of all procedures, and quality assurance are of utmost necessity, these topics will be addressed.
A Rare Cause of Fatty Liver and Elevated Aminotransferase Levels: Chanarin-Dorfman Syndrome: A Case Report
Authors: Ersoy Özdal , Alkım Canan , Onuk Mehmet Derya , Demirsoy Hüseyin , Argon Dilek
Published: January 2011

Chanarin-Dorfman syndrome is a rare, inherited metabolic disorder of neutral lipid storage characterized by ichthyosis, lipid vacuoles in leukocytes, and involvement of several internal organs, mostly the liver. Since the initial case was reported by Dorfman in 1974, nearly 50 cases have been reported, and the majority were from Middle East countries. Here, we report a 20-year-old patient with ichthyosis from Turkey, diagnosed as Chanarin-Dorfman syndrome presented with asypmtomatic elevated transaminases and hepatosteatosis, and also briefly review the updated clinical implications and management of this rarely seen syndrome. Prompt diagnosis of this syndrome avoids further unnecessary investigations in patients with ichthyosis

Published: January 2011

A case of multifocal Langerhans cell histiocytosis in a two-year-old child is presented where fine needle aspiration was helpful in achieving a rapid and accurate diagnosis in an appropriate clinical and radiological setting. This can avoid unnecessary biopsy and guide the management especially where access to histopathology is limited. The highly characteristic common and rare cytological features are highlighted with focus on differential diagnoses and causes of pitfalls.
MRP8/ABCC11 Expression Is Regulated by Dexamethasone in Breast Cancer Cells and Is Associated to Progesterone Receptor Status in Breast Tumors
Authors: Honorat Mylène , Mesnier Aurélia , Vendrell Julie , Di Pietro Attilio , Lin Valérie , Dumontet Charles , Cohen Pascale , Payen Léa
Published: January 2011

The ATP-binding cassette multidrug resistance protein 8 (MRP8/ABCC11) mediates the excretion of anticancer drugs. ABCC11 mRNA and protein levels were enhanced by DEX (dexamethasone) and by PROG (progesterone) in MCF7 (progesterone receptor-(PR-) positive) but not in MDA-MB-231 (PR-negative) breast cancer cells. This suggested a PR-signaling pathway involvement in ABCC11 regulation. Nevertheless, pregnenolone-16α-carbonitrile (GR antagonist) and clotrimazole strongly and moderately decreased ABCC11 expression levels in Glucocortocoid Receptor-(GR-) and Pregnane X Receptor (PXR)-positive MCF7 cells but not in MDA-MB-231 cells (GR- and PXR-positive). Thus, GR-signaling pathway involvement could not be excluded in ABCC11 regulation in MCF7 cells. Furthermore, ABCC11 levels were positively correlated with the PR status of postmenopausal patient breast tumors from two independent cohorts. Thus, in the subclass of breast tumors (Estrogen Receptor-(ER-) negative/PR-positive), the elevated expression level of ABCC11 may alter the sensitivity to ABCC11 anticancer substrates, especially under treatment combinations with DEX.
Edéhzhíe candidate protected area hydrocarbon assessment summary report
Authors: Morrow D W
Published: January 2011

The Edéhzhíe candidate protected area falls entirely within the Great Slave Plain physiographic region. Horn Plateau, a large upland area, is the dominant physiographic feature. Edéhzhíe has a low to moderate potential for natural gas and low oil
potential. Quantitative estimates indicate that the ultimate potential of the Edéhzhíe candidate protected area is about 0.23 trillion cubic feet of natural gas. Devonian Horn Plateau reefs are the most prospective gas reservoirs, but some gas can also be expected to occur in underlying
Paleozoic carbonates and the Cambrian Mount Clark sandstone in northeast Edéhzhíe. Oil potential is not significant and is about half a million barrels in the basal Cretaceous sandstones beneath Horn Plateau.

Sambaa K'e candidate protected area hydrocarbon assessment summary report
Authors: Morrow D W
Published: January 2011

The Sambaa K'e candidate protected area lies within the Great Slave Plain physiographic region southwest of Great Slave Lake and is centered on the community of Trout Lake. Gently southwest-dipping Devonian carbonate and siliciclastic strata that underlie this
region contain numerous gas shows and several significant gas discoveries, one of which is within the Sambaa K'e area. Quantitative estimates indicate that the ultimate potential for additional undiscovered petroleum within the outer boundary of the Sambaa K'e candidate protected area is about 13.3
billion cubic meters, or 470 billion cubic feet of gas, and about 1.18 million cubic meters, or 7.4 million barrels of oil. Most of this gas potential lies within the Upper Devonian Jean Marie Formation and within the Middle Devonian Slave and Sulphur Point formations along the subsurface Devonian
Presqu'ile barrier reef complex. Most of the undiscovered oil potential resides within the Mississippian subcrop play.
Porosity and permeability evaluation and geological interpretations from core data and geophysical well logs for 18 wells in the Paleozoic successions of eastern Canada and implications for hydrocarbon exploration
Authors: Hu K , Lavoie D
Published: January 2011

As part of the Hydrocarbon Resource Evaluation of the Gulf of St. Lawrence and Adjacent Paleozoic Onshore Project, part of the Secure Canadian Energy Supply Program, detailed log analyses were carried out on 18 wells from Eastern Canada. The wells were drilled
between the late 1960s and 2000 to test sections of the Paleozoic successions, and the suite of available logs and their quality is quite variable. Simple log correlations were done and adjustments are proposed for formation tops.

Fair to good reservoir potential exits in the various geological domains. Pennsylvanian sandstones of the Maritimes Basin have fair to good reservoir potential; Lower and Middle Ordovician fractured hydrothermal dolostone units of the St. Lawrence Platform have fair reservoir potential; Lower
Devonian sandstone of the Gaspé Belt has good potential (whereas the Lower Devonian fractured limestone has fair potential, although recently field-documented dolostone targets were not identified in the studied wells); and fractured Lower Cambrian sandstones of the Humber Zone have good
potential.

Surficial geology and landslide inventory of the lower Sea to Sky corridor, British Columbia
Authors: Blais-Stevens A
Published: January 2011

The surficial geology and landslide inventory of the Lower Sea to Sky Corridor provides a record of the late Quaternary history of the map area in southern British Columbia near the edge of the former Cordilleran Ice Sheet. The map depicts a variety of sediment
units of glacial and non-glacial origin superposed on a hillshade DEM. From oldest to youngest, the units are bedrock, till, glaciofluvial deposits, glaciomarine deposits, alluvium, colluvium, and organic deposits. Landslides are identified and classified in the colluvium units. Till, was deposited
by glacier ice and consists of boulder- to pebble-sized clasts in a matrix of sand, silt, and clay. Glaciofluvial deposits consist of stratified, well sorted to poorly sorted sand and gravel. They are associated with terraces and blankets. Glaciomarine deposits consist of stratified, well sorted to
poorly sorted sand, gravel and silty clay muds. They are also fossiliferous in some places. They are associated with terraces and blankets. Alluvium consists of fine silt, sand, and minor gravel deposited along modern streams after deglaciation. Colluvium is derived from bedrock, till, or
glaciofluvial deposits that failed. Organic deposits include peat and organic-rich muds that have accumulated in poorly drained depressions formed in older sediments and bedrock.

Indicator mineralogy of a kimberlite cobble from an esker on the southeastern flank of the Buffalo Head Hills, northern Alberta
Authors: McClenaghan M B , Kjarsgaard I M , Paulen R C , Eccles D R
Published: January 2011

This report describes the indicator mineral abundance and composition of kimberlite cobble 03-MPB-009 from an esker on the southeast flank of the Buffalo Head Hills, northern Alberta. The Buffalo Head Hills kimberlite field consists of 38 kimberlites intruded
into poorly indurated Cretaceous host rocks. The source esker is the 2 km southern segment of a discontinuous chain of ice-contact sediments extending 7 km to the north. Numerous kimberlite fragments have been recovered from pits in this esker segment since 1997. Olivine and chromite are the most
abundant indicator minerals in the kimberlite cobble, Cr-pyrope and Crdiopside occur only in minor amounts and Mg-ilmenite is absent. The cobble also contains pink chromian corundum and hercynite (Mg, Fe-Al-spinel), which are known minor minerals in Buffalo Head Hills' kimberlites and can also be
used as kimberlite indicator minerals in the region. The indicator mineral suite found in the cobble confirms the presence of several lithologies of mantle xenoliths in the Buffalo Head Hills kimberlites: fertile garnet-lherzolite and garnet-harzburgite, sheared garnet-lherzolite, garnet-wehrlite,
garnet-pyroxenite, garnet-websterite, Group II eclogite, spinel lherzolite and chromian corundum-bearing high Al assemblages that also include Mg-Al-spinel. Although several studies document mantle xenolith and indicator mineral compositions from some of the Buffalo Head Hills kimberlites,
insufficient data are available to characterize the indicator mineral abundance and composition of individual kimberlites in the Buffalo Head Hills field. Thus comparison between the kimberlite cobble studied here and potential source kimberlites is vague and the cobble's source cannot be
determined. Southward paleocurrent flow directions for the host glaciofluvial sand deposits combined with late-stage ice flow towards the southeast and south suggest that the likely up-flow direction to search for the cobble's source is north. The nearest kimberlites up-flow and up-ice are K5, K6,
and K14, and one of these may be the bedrock source of the cobble.

Hydrocarbon potential of the Tertiary succession of Intermontane Basins of the Cordillera: preliminary conceptual synthesis of background data
Authors: Hamblin A P
Published: January 2011

The hydrocarbon potential of the Tertiary intermontane basins of southern British Columbia has never been seriously studied, and is currently poorly understood. Aside from minor hydrocarbon exploration in Kishenehn Basin, only limited coal exploration (mostly in
the earlier part of the 20th century) has been attempted in these basins, and they must be viewed as rank frontier prospects, but situated near important markets. The fault-bounded basins are geographically small, geologically complex and their potential is currently poorly constrained. A
relatively high regional geothermal gradient, abundant sandstone reservoir facies, known thick lacustrine source rock mudstones, abundant coals, the presence of shows in one basin, an extensive regional seal of Plateau Basalts and the location near populous markets are all positive factors,
suggesting significant potential. Conversely, a simple lack of knowledge makes petroleum system analysis very difficult, until further data are available. This will require concerted geological and geophysical field work and several stratigraphic test wells in each basin.
Landslide geohazard mapping in complex terrains
Authors: Huntley D H
Published: January 2011

The interaction between high relief, steep slopes, heavy precipitation, complex tectonic and geomorphic history, land uses, and the range of surficial deposits and bedrock can produce a variety of landslide types in many regions of the. In this paper, an
effective approach is presented for the classification and mapping of terrain and landslide geohazards from stereo-pair air photographs, satellite imagery and benchmarking field studies in a region of mountainous terrain and discontinuous permafrost in Northwest Canada prone to earthquakes, mass
wasting, wildfires and sensitive to the impacts of climate change. Digital terrain and landslide hazard maps and their accompanying geodatabases provide essential information for land management decisions regarding construction of pipelines, highways and settlements; evaluation of property rights
decisions; extraction of fossil fuels, minerais, aggregates and groundwater; assessments of environmental risk and impact, ecological sensitivity and archaeological potential. GIS maps and geodatabases also provide calibration for future predictive landslide mapping and hazard analyses. Qualitative,
semi-quantitative and quantitative analyses of landslide distribution, activity and density maps derived from terrain and landslide inventory geodatabases can improve the understanding of landslide processes in a region. Important outcomes that can be achieved through the use of geoscience
databases, landslide hazard maps and related products include the attraction of new investment and reduction of risks for regional development. Outreach initiatives can also increase professional and public understanding and awareness of landslide hazards and related geoenvironmental
issues.
Fourth generation seismic hazard maps of Canada: Maps and grid values to be used with the 2005 National Building Code of Canada
Authors: Halchuk S , Adams J
Published: January 2011

Canada's 4 Generation seismic th hazard model is the basis for the seismic design provisions in the 2005 National Building Code of Canada. The 2005 code uses median ground motion on firm soil sites for a probability of exceedence of 2% in 50 years, with the
ground motion being described by seismic hazard values for five parameters: spectral acceleration at 0.2, 0.5, 1.0 and 2.0 second periods and peak acceleration. We tabulate values of the five parameters for more than 200,000 grid points over Canadian territory and surrounding areas. The four
spectral parameters will allow the construction of approximate uniform hazard spectra for every place in Canada, and hence improve earthquake-resistant design.
Qualitative assessment of the Plateau Fault (Mackenzie Mountains, NWT) as a conceptual hydrocarbon play
Authors: MacNaughton R B , Fallas K M , Zantvoort W
Published: January 2011

The Plateau Fault (Mackenzie Mountains, Northwest Territories) has been suggested as a possible dry-gas hydrocarbon play, based on its interpreted character as a low-angle overthrust of regional extent. Qualitative assessment of its hydrocarbon potential has been
carried out, based on archivai data and new data derived from bedrock mapping and sampling. Thermal-maturity data, mainly from microfossils, indicate some potential for dry-gas generation and preservation within the Mackenzie Platform succession and younger strata. The only likely source rocks,
however, are in shale-dominated, Upper Devonian strata, in particular the Hare Indian and Canol formations. Argillaceous limestone of the Middle Devonian Headless Formation is expected to act as a seal, preventing downward charging of potential reservoirs in the Mackenzie Platform succession.
Sandstone beds in the Upper Devonian Imperia! Formation may have reservoir potential. Geological data permit the Plateau Fault to be interpreted as a low-angle thrust. Even the most favourable overthrust scenario, however, does not permit significant preservation of potential reservoirs of Silurian
to Upper Devonian age beneath the hanging-wall panel. Based on these considerations, the Plateau Fault is unlikely to constitute a large-scale hydrocarbon play, although there may be limited trapping potential beneath its leading edge.
Preliminary interpretations of detailed mapping in the Chilcotin Group, Chasm Provincial Park, British Columbia
Authors: Farrell R -E , Simpson K A , Andrews G D M , Russell J K , Anderson R G
Published: January 2011

Within Chasm Provincial Park, the Chilcotin Group basalt overlies rocks of the Permian Cache Creek Group, the Eocene Kamloops Group, and the Miocene Deadman River Formation. Detailed mapping of the Chilcotin Group has identifi ed a variety of subaqueous and
subaerial volcanic and sedimentary facies. Within the coherent rocks, three distinct facies have been described, 1) plagioclase-phyric basalt (Pp), 2) aphyric columnar-jointed basalt (Ac), and 3) aphyric massive basalt (Am). All coherent facies are interpreted as subaerial, fl at-lying basalt lavas.
Clastic facies include pillow-fragment breccia (Pf) and sandstone-to-breccia (Sb). The presence of intact pillows, pillow fragments, and hyaloclastite within the pillow-fragment breccia facies provides evidence for a local subaqueous environment. The sandstone-to-breccia units occur between the
coherent lava units and are interpreted as paleosols that represent volcanic hiatuses during emplacement of the Chilcotin Group lavas.
Estimated seismic design values for Canadian missions abroad
Authors: Adams J , Halchuk S , Awatta A
Published: January 2011

Seismic hazard design values are estimated for 161 Canadian Missions abroad. The method is broadly based on applying spectral shape and magnification factors to move from the 10%-in-50-year Peak horizontal Ground Acceleration (PGA) values given by the Global
Seismic Hazard Assessment Program (GSHAP) to the 2%-in-50-year PGA and spectral acceleration values desired. The factors were derived from Canadian seismic hazard results, and the resulting design factors are intended to be applied in the context of the Canadian Building Code in order to deliver
appropriate safety to the Missions and continuity of consular services.
Hydrocarbon potential of the uppermost Cretaceous-Tertiary succession of Western Canada Sedimentary Basin: Preliminary conceptual synthesis of background data
Authors: Hamblin A P
Published: January 2011

The hydrocarbon potential of the upper Cretaceous/Tertiary was first realized in the 1880s with the discovery of gas at Medicine Hat, followed by the discovery of oil at Pembina in the 1950s. Development continues today with active exploration for shallow gas
and coal-bed methane in central Alberta. Although thousands of wells have penetrated these strata and 1700 oil and gas pools have been discovered, they are still vastly under-explored because they represent such an enormous volume of rock with excellent further potential which has not been a focus
of active exploration until recently. A large volume of gas, distributed through a large number of pools, is estimated yet to be discovered. Laterally extensive and mappable reservoir trends and shallow drilling depth ensure scientific and economic success in gas exploration, and coal-bed methane
and biogenic gas are emerging concepts with further potential. Low reservoir pressure, modest pool size, drilling damage and the lack of basic geological work on several prospective units are challenges to be overcome.
Nares transform motion and Eurekan compression along the northeast coast of Ellesmere Island
Authors: Tessensohn F , von Gosen W , Piepjohn K , Saalmann K , Mayr U
Published: January 2011

The Wegener Fault is a sinistral continental transform fault between spreading areas in the Labrador Sea/Baffi n Bay and the Arctic Ocean. It separates Greenland from Arctic Canada and is inferred to run through the straight seaway of Nares Strait between
Ellesmere Island and North Greenland. Analysis and distinction of tectonic structures formed by the postulated Nares Strait transform movement and by the Eurekan compressive event were the main objectives for fi eldwork on Ellesmere Island along the coast of Nares Strait. In the south, the Paleozoic
units are fairly regularly arranged in the form of long, continuous Ellesmerian anticlines and synclines as part of major thrust sheets. In contrast, the geological picture becomes irregu- lar and broken up in the northern part of the area. There, the Ellesmerian structures are overprinted by a
younger, brittle system of strike-slip faults.
Evaluation of hydrocarbon reservoir potential in Carboniferous sandstones in six wells in the Maritimes Basin, Eastern Canada
Authors: Hu K , Dietrich J
Published: January 2011

The reservoir characteristics of Carboniferous sandstones in six wells in the western Maritimes Basin in the Gulf of St. Lawrence region in eastern Canada are evaluated through detailed analyses of geophysical well logs and core data. The wells include Bradelle
L-49, Brion Island No.1, Irishtown No.1, Cable Head E-95 and East Point E-49 in the Magdalen Basin and North Sydney F-24 in the Sydney Basin. Compiled and/or calculated reservoir parameters for each well include lithology, clay mineralogy, porosity, permeability, water saturation and drill-stem test
data. Possible hydrocarbon zones are also identified. Porosity-depth trends are derived and discussed in terms of well reservoir potential and stratigraphic and geographic reservoir variations. Significant hydrocarbon reservoir potential is identified in sandstones in the Upper Carboniferous Pictou
and Mabou groups and the Lower Carboniferous Horton Group. Upper Carboniferous sandstones in the northern Magdalen Basin appear to have the best overall reservoir quality in the study region.

Petroleum play data for Upper Devonian to Carboniferous siliciclastics (Imperial and Tuttle formations), Mackenzie corridor
Authors: Pyle L J , Allen T L , Fraser T A , Zantvoort W G
Published: January 2011

Petroleum resource assessment of Mackenzie Corridor is underway as part of the Geological Survey of Canada's "Secure Canadian Energy Supply" program. The Mackenzie Corridor Project examines hydrocarbon potential in subsurface regions east and west of the proposed
route of the Mackenzie Valley Pipeline for this part of the northern Canadian mainland sedimentary basin. Two conceptual plays of interest are the Upper Devonian Imperial Formation clastics and the Upper Devonian-Lower Carboniferous Tuttle Formation clastics. This succession occurs in the Interior
Plains exploration region and northern foreland and represents a southwestward progradational clastic wedge succession deposited in the foreland of the Arctic Ellesmerian Orogeny. Although there have been no discoveries in the regions assessed herein, indications of petroleum systems occur such as
hints of gas in drill stem tests in the Imperial Formation and minor gas detected in the Tuttle Formation. Potential source rocks, based on analysis of total organic carbon (%TOC), include Road River Group (0.06 to 3.67 % TOC in subsurface and 1.58 to 2.28 %TOC in surface samples), Canol
Formation (0.01 to 27.14 %TOC in subsurface and 0.2 to 8.51 %TOC in surface samples), Imperial Formation (range from 0.01 to 7.49 %TOC in subsurface and 0.27 to 7.03 %TOC in surface samples), Tuttle Formation (0.48 to 5.42 %TOC in subsurface and 0.28 to 40.25 %TOC in surface
samples), Ford Lake Shale/"Cf" unit (0.01 to 2.77 %TOC in subsurface and 0.03-12.17%TOC in surface samples), and Cretaceous formations (range from 0.01 to 42.4 %TOC in subsurface samples). Potential reservoir horizons in the Imperial Formation include sandier units with intergranular
porosity (range from 0.5% to 24.7%) and permeability generally less than 0.1 mD. Tuttle Formation sandstone and conglomerate units have intergranular and intragranular porosity (range from 1.5 to 25.6%) and permeability ranges between 0 and 127 mD. Reservoir seals include
intraformational shale and overlying shale. Both stratigraphic and structural traps are possible for each play, including channelized sandstone or lateral pinch-outs of sandstone beds, interfingering relationships of the Imperial and Tuttle formations, and minor folds and faults particularly in the
zone parallel to the Richardson Mountains. Exploration risks include: preservational risk from the sub-Cretaceous unconformity, shallowness of reservoirs, quality and thickness of reservoirs, and timing of hydrocarbon generation in relationship to trap formation.

Sedimentology of aggregate pits between Waterloo and London, southern Ontario: a reconnaissance survey for groundwater
applications
Authors: Russell H A J , Cummings D I , Sharpe D R , Bajc A
Published: January 2011

Thirty-three aggregate pits between Cambridge and London are documented. The pits are situated in a variety of landforms (moraines, drumlinized uplands, hummocky terrain, outwash plains), geological map units, and stratigraphic positions. Many have not been
documented previously. The objective was to capture a snapshot of the general sedimentary character of as many pits as possible in a four day timeframe.
For each pit, a point form summary is provided followed by a general description and photographs that document the facies architecture of the deposits. A summary section provides a brief synthesis of the observations and highlights three key hydrogeological points that can be further understood by
study of these deposits.
Detailed sedimentological observation in this integrated regional framework provides the opportunity to begin a re-assessment of the underlying conceptual geological models for parts of southern Ontario.
Porosity and permeability measurements for selected Paleozoic samples in Quebec
Authors: Lavoie D
Published: January 2011

A total of 167 field samples were collected in 2005 and 2006 in order to provide some porosity and permeability data for Paleozoic rocks in Quebec. Samples were collected in the three major tectonostratigraphic domains of the Paleozoic of Quebec; namely the
Cambrian-Ordovician shallow marine St. Lawrence Platform (southern Quebec and Anticosti Island), the coeval deep-water sediments preserved in the Taconian Humber Zone (eastern Quebec) and the late Ordovician to Middle Devonian Gaspé Belt (Gaspé Peninsula). Two samples were taken from the
thin Carboniferous veneer in southern Gaspé Peninsula. Porosity and permeability measurements were realized at the AGAT laboratories in Calgary. In all domains, some sandstones have relatively high porosity and permeability values. Carbonates are generally characterized by low porosity and
permeability values, except for hydrothermal dolomites.

The Boothia mainland area, part of the north-central Rae Province, comprises a high-grade gneissic terrain dominated by Neoarchean metaplutonic rocks, migmatitic gneiss, Archean supracrustal rocks, and rare Paleoproterozoic supracrustal rocks. The Archean
supracrustal rocks are inferred to be cor- relative with the regionally widespread Prince Albert Group. Granitic rocks and their gneissic equivalents are dominated by meta- to peraluminous, polyphase, commonly porphyritic, biotite- and hornblende-bear- ing monzogranite to granodiorite. U-Pb zircon
ages indicate they are part of a 2.61 to 2.59 Ga magmatic event recognized throughout most of the Rae Province. Lesser 2.67 to 2.66 Ga plutonism represents a previously unknown age of magmatism in the Rae Province. Small outliers of Paleoproterozoic Chantrey Group metasedimentary rocks (Burwash Lake
belt) occur as complex infolds in the Archean rocks, and cor- relate with other Rae Province Paleoproterozoic cover sequences, such as the Amer and Piling groups. The dominant structural fabric of the study area is a moderately to intensely developed regional trans- position foliation (S1), which is
folded about map-scale, northeast-trending, Paleoproterozoic F4 folds, doubly plunging about less pervasive north-northwest-trending F5 folds. High-grade (granulite to upper amphibolite facies) metamorphism and migmatization is interpreted to have occurred during 2.6, 2.5, and 1.82 Ga metamorphic
events. The north-central Rae Province has signifi cant exploration potential for diamonds. In addition, the Archean metavolcanic rocks in the area have exploration potential for base and precious metals.
Geomorphic impact of a beaver dam outbreak flood, Gatineau Hills, Quebec: a pictorial record

On July 20th, 2007 Ottawa received 67.8 mm of rainfall, a near record amount for that date. Thirty kilometres to the north in the forested upland of the Canadian Shield, the intense rainfall caused two beaver dams to fail sequentially. The flow descended about
90 m in elevation along a < 1 km long, steep, rock-floored stream before it expanded across a bouldery, vegetated, and inhabited subaerial fan to discharge into Lake McArthur. The flood eroded soil, sediment, and vegetation along the length of the stream. Flow across the subaerial fan
inundated one chalet to a depth of 1 m and rafted a smaller building several metres. Expansion bars were deposited at various flow expansion points; however, the most noteworthy deposit is a gravel delta that extends 10 m into the lake. Using a dam break model the peak discharge is estimated at
about 70 m3 s-1 which is likely two orders of magnitude greater than average summer discharges. Given the coarseness of the bed material and the small discharge typical of the stream, it is likely that most bed material in the past has been mobilized during similar dam break floods. The study
highlights the hazard posed by beaver dams to human infrastructure in steep terrain, and demonstrates that beaver dam outbreak floods can be the predominant agent of geomorphic change in small fluvial systems.
Hydrothermal Alteration Study of the VMS-hosting Paleoproterozoic Bear Lake volcanic suite, Flin Flon Belt, Northern Manitoba
Authors: Galley A , Bailes A , Hillary E , Taylor B
Published: January 2011

The Bear Lake suite of the Paleoproterozoic Flin Flon Arc Assemblage consists of a large basaltic andesite shield volcano crowned by a caldera containing effusive to volcaniclastic rhyolite to andesite flows and a thick pelitic unit, the latter which hosts the
White Lake and Cuprus volcanogenic massive sulphide deposits (VMS). The Bear Lake suite is also host to an extensive zone of epidote-enriched synvolcanic hydrothermal alteration over 11 km by 3 km in dimension. This alteration zone is similar in size to that of the VMS-rich Archean Noranda cauldron
succession and yet contains an exponentially smaller VMS tonnage. Detailed mapping and geochemical analysis of the alteration zone indicates redistribution of large amounts of base metals unaccounted for in the presently known VMS deposits, suggesting good base metal exploration potential still
exists within this oceanic arc succession.

Authors: Avery M P
Published: January 2011

Vitrinite reflectance on the 19 samples from the Mackenzie Corridor yielded the following 4 maturity groups. Four samples from the Redstone River and Old Fort areas were immature. Five samples from the Sigma line W4, Redstone River and Keele River areas were
mature to overmature. Four samples from the Sigma line W6 & 7 areas were marginally mature. Four samples from the Cadillac Mine were overmature. Two samples did not produce any reflectance values.
Palynology, age, correlation, and paleoclimatology from JAPEX/JNOC/GSC Mallik 2L-38 gas hydrate research well and the significance for gas hydrate: a new approach
Authors: White J M
Published: January 2011

A quantitative palynological study of a 480 m section of mid-Cenozoic sediment from the Mallik 2L-38 gas hydrate research borehole, Mackenzie River delta, is based on core and high-quality cuttings. The degree of recycling of palynomorphs requires evaluation
because recycled palynomorphs can compromise biostratigraphic age determinations. The study proposes that a biologically driven palynomorph series will be more directional and ordered than a series dominated by recycling. The palynological count data are evaluated by several techniques and it is
concluded that they present a primary biostratigraphic pattern amenable to interpretation. Results revise previous palynological age determinations. The age of the interval from 1150 m (total depth) to the unconformity at 926 m is interpreted to be Late Eocene, and from the unconformity to 670 m,
the top of the cuttings, is Oligocene and perhaps Early Miocene. An experimental approach to refining age determinations is calculation of four independent ratios of pollen taxa that are likely to reflect paleotemperatures, and correlation of the results to the North Atlantic Ocean foraminiferal
delta18O curve. Two ratios, (thermophilous angiosperms minus Ulmus)/total angiosperms and Taxodiaceae-Cupressaceae-Taxaceae/Pinaceae, are most consistent and suggest a long-term cooling trend culminating about 890 m, tentatively correlated with the early Oligocene cold period. This is at the top of
the interval that subsequently hosted gas hydrate, and suggests some mechanism such as lithological change contributed to the gas accumulation. A short core from 110 - 118 m is Late Pliocene - Pleistocene.
Reconnaissance sub-bottom profiling studies of Peyto Lake, Banff National Park
Authors: Medioli B E , Demuth M N
Published: January 2011

Recent studies have pointed to significant negative flow trends in the glacierized catchments of Canada's Southern Cordillera. These trends and a reduction in the flow regulation effect of glacier cover are due to marked reductions in the aerial extent of
glaciers over the last half of the 20th Century (Hopkinson and Young 1998; Moore and Demuth 2001; Demuth and Pietroniro 2002; and Stahl and Moore 2006). These conclusions are the result of analyses conducted using the available instrumental records describing summer month river flows.
In the context of water resources, and to better define the warmdry climate episode adaptation limits provided by the presence of glaciers, it is desirable to place these observations within the perspective of glacier fluctuations that have taken place over the last several millennia. In several
instances recent and paleoglacier fluctuations from direct or proxy evidence have been well documented. For example, Demuth (1997), Demuth and Keller (2006), Hopkinson and Demuth (2006), Luckman (2006), and Watson and Luckman (2004) provide such evidence for Peyto Glacier. Peyto Glacier is situated
in the eastern slopes of the Canadian Rocky Mountains and provides flow to the North Saskatchewan River Basin. This glacierized mountainous headwater region plays a critical role in providing orographically derived precipitation, seasonal snowmelt and glacier melt to natural and human systems
downstream.
Quartz dioritic magmas and Cu-(Ni)-PGE mineralization, Podolsky Deposit, Whistle Offset Structure, Sudbury, Ontario

The Whistle Offset, emanating from the northeastern corner of the 1.85 Ga Sudbury Igneous Complex (NTS 41-I/15), is atypical, as it contains three intrusive phases of 'quartz dioritic' magma that occur as pods instead of a continuous dyke.
Lithogeochemical analyses reveal compositional similarities between the quartz dioritic phases and the footwall breccia, but expose a subdivision that supports the hypothesis that the leucocratic quartz diorite is earlier than the quartz diorite and inclusion quartz diorite, and is derived from the
same rock types as the footwall breccia.
Mineral, chemical, and textural features within the quartz dioritic phases include stellate amphibole, granophyric intergrowths, and elongate fluorapatite with axial melt inclusions and irregular rare earth element zoning, which suggest disequilibrium conditions during crystallization. This is
interpreted to indicate rapid crystallization induced by volatile loss through pressure decrease during readjustment of the crater. Leucocratic quartz diorite is interpreted as the original composition of the undifferentiated melt sheet in the Whistle offset area. Inclusion quartz diorite represents
an early phase of the melt sheet, where silicate differentiation, assimilation, and gravitational segregation had initiated. Readjustment of the crater caused rapid crystallization of the leucocratic quartz diorite, and injected a pulse of inclusion quartz diorite into the structure. The quartz
diorite is believed to have developed in the offset structure directly from the inclusion quartz diorite melt. High temperatures would have produced convective cells in the inclusion quartz diorite melt, and the circulatory movement induced by these cells would cause clastic material to concentrate
in low velocity areas, essentially creating inclusion-free pods of quartz diorite.
Mineralization ranges from disseminated to blebby Ni-Cu sulphides to vein-style Cu-(Ni)-PGE-rich sulphides rimmed by epidote and/or chlorite. The association with hydrous silicate alteration minerals, together with irregular vein morphology, implies that the Cu-PGE-rich mineralization was
concentrated by a fluid and precipitated when the fluid flow was choked.
