Sedimentation rates and surficial geology in the Canadian Forces Maritimes Experimental and Test Range exercise area Whiskey Golf, Strait of Georgia, British Columbia
Authors: Picard K , Hill P R , Johannessen S
C
Published: November 2010

Bathymetric and geological studies were undertaken in the Canadian Forces Maritimes Experimental and Test Range Whiskey Golf, Strait of Georgia, using multibeam echosounder, high-resolution seismic reflection, sidescan sonar, and sampling data. This work was
completed in conjunction with the Department of National Defense and the Royal Military College (Kingston, Ontario). The objectives were
to map seafloor features and determine the modern depositional regime in order to support environmental assessment of test-range activities. Detailed analysis of the data revealed a maximum thickness of late Holocene sediments of 21 m and the best estimate for the present-day sedimentation rate in
the basin is 0.54 cm/a. The sedimentation rate has likely increased over the last 1500 years. The study demonstrates that previous interpretation of seismic data led to overestimates of sedimentation rate.
Geoart in the south-central Mackenzie River valley region, Northwest Territories
Authors: Huntley D
Published: November 2010

Acrylic and oil paintings of the south-central Mackenzie River valley region, Northwest Territories depict the landscape as a product of multiple cycles of glacial and fluvial incision driven by plate-tectonic processes and climate change operating over millions
of years. Folded and thrust-faulted mountain ranges were drained by rivers flowing eastward toward Hudson Bay and the northeastern Arctic coast prior to the last glaciation. As continental ice advanced westward into the region, this paleodrainage system was blocked and deranged. At its maximum
extent, continental ice was confluent with local ice fields and valley glaciers. Some montane valleys remained unglaciated and were infilled with outwash, lake sediments, and landslide deposits. During glacial retreat, outwash and stagnant ice dammed meltwater outlets, creating an interconnected
system of proglacial lakes. Retreating ice and postglacial uplift reordered meltwater flow directions so that these lakes, and subsequently the modern Mackenzie River, drained north into the Beaufort Sea.
Petroleum Resource Assessment, Eagle Plain Basin and environs, Yukon Territory, Canada
Authors: Osadetz K G , Chen Z , Bird T D
Published: November 2010

The Eagle Plain Basin and its environs is a potentially prospective petroleum province in the Yukon. Extensive initial exploration in this area, focused on discovering crude oil, identified 83.7 Bcf of natural gas and 11.05 MMbbls of crude oil, with 33 wells,
many of which had shows of petroleum in other zones, throughout the succession and across the geographic extent of the basin. A probabilistic petroleum assessment of 15 petroleum plays suggests that an expected 5.971 Tcf of natural gas and 425.95 MMbbls of crude oil remain to be discovered, as part
of a total resource endowment in 146 accumulations of crude oil and natural gas containing between 2.379 Tcf to 12.0 Tcf of natural gas, and 132 MMbbls to 926 MMbbls of crude oil. This study differs significantly from previous estimates of undiscovered potential, which were less optimistic. The
total expected petroleum endowment of the Cambrian to Middle Devonian carbonate succession is 1327.86 Bcf of natural gas, which remains an important secondary deeper exploration target. The main target is the Permo-Carboniferous succession, with three main potential reservoirs, at the base (Tuttle
Formation), in the middle (Hart River Formation) and at the top (Jungle Creek Formation) of the succession. The Tuttle Formation is expected to have resources of 323.02 Bcf of natural gas and 68.95 MMbbls of crude oil. Another 1823.32 Bcf and 155.09 MMbbls are inferred for the Hart River Formation,
while the Jungle Creek Formation is expected to contain 2231.8 Bcf and 104.89 MMbbls. The expected potential in the Mesozoic succession is 349.34 Bcf and 107.81 MMbbls, an important up-hole interval. While the entire section is prospective, plays that target structural and stratigraphic prospects in
the upper part of the Paleozoic succession are the best targets, as these form major traps at and near the top of the succession that contain thermally mature sources, below major regional seals, which are commonly involved in Laramide structures. Predicted undiscovered pool sizes point toward
success accompanying the continued exploration of plays in the Permian and Carboniferous successions, with a new focus on Jungle Creek Formation sandstones. These results are consistent with the exploration history, the stratigraphic architecture and the analysis of petroleum systems. Intriguing
plays exist associated with the stratigraphic opportunities for entrapment in Paleozoic carbonates against the Richardson Trough, but these appear to be higher risk/reward targets than the continued exploration of the uppermost Paleozoic succession. Additional conceptual play concepts, including
those in the Devonian Imperial and Jurassic Porcupine River formations, which have indications of petroleum occurrence, were not quantitatively assessed.
Interim report on the characterization of Jean Marie gas reservoir facies in the July Lake area of northeastern British Columbia
Authors: Wendte J C , Sargent D G , Al-Aasm I S
Published: November 2010

This report provides a summary of the stratigraphic evolution of the Upper Devonian Jean Marie Member (Redknife Formation) and a characterization of its major reservoir facies from the July Lake area of northeastern British Columbia. Six cross-sections, based on
the description of 18 m cores from 18 wells, show the cyclic makeup of the Jean Marie Member and the distribution of its major depositional facies. An interpretive cross-section, based on the distribution of facies in these cross-sections, provides a model illustrating the evolution of the Jean
Marie Member in the July Lake area. Three main growth stages are identified. In the July Lake area, three major reservoir facies are recognized. Pore networks in these reservoir facies are highly variable because of the interaction of depositional, diagenetic and tectonic processes. In addition,
the results of the initial stable and radiogenic isotopic analyses of the main diagenetic components are made available.
The "shale gas" concept in Canada: a preliminary inventory of possibilities
Authors: Hamblin A P
Published: November 2010

The term "Shale Gas" refers to unconventional, continuous-type, self-sourced resources contained in fine grained (ranging from clay to very fine sandstone), organic-rich, low permeability reservoirs in which thermogenic or biogenic methane is stored as free gas
in the matrix or fracture porosity, or as adsorbed/dissolved gas on the organics and/or clays. These are self-enclosed petroleum systems, characterized by inefficient "dysfunctional" expulsion and migration, where source, reservoir and trap are all present in the same thick shaly succession. The
most prospective shale gas targets will be thick, widespread, gas-saturated, fine grained, organic-rich units with a) significant Type III (terrestrial, gas-prone) organic matter in thermally mature to overmature states, b) significant Type II (marine, oil- and gas-prone) organic matter in a
thermally overmature state, and/or c) rich organic matter of any type that is thermally immature and subject to extensive biogenic decomposition. The current economic climate of depleting conventional reserves and rising prices presents an opportunity for the emergence of the shale gas concept in
Canada, although significant environmental concerns must be addressed from the beginning. Successful shale gas production has a long history in the USA and each of the four (or more) known play types (Antrim, Ohio/New Albany, Barnett, Lewis) owes its success to different balances of the controlling
factors of TOC, thermal maturity, lithology, mineralogy, depth, fracturing, production technique and infrastructure. Entirely new, undescribed, play styles probably still exist. Intensive and detailed, pre-drill, geological study of each potential shale gas play is an inexpensive and efficient
method for technical evaluation, to properly assess the economic possibilities, choice of target and recovery of resources. Canada's sedimentary basins collectively provide numerous (perhaps 50) possible shale gas targets, scattered over at least 7 regions. Of these, seven represent regional-scale
units with enough geological prospectivity to justify concerted geological study due to the presence of one or more of excellent geological potential, geographic location, proximity to infrastructure, and/or relation to known conventional and unconventional plays. They are: Upper Ordovician of
Appalachian Basin, Upper Devonian of Appalachian/Michigan Basin, Upper Devonian of northwestern WCSB, Triassic of northwestern WCSB, Jurassic of western WCSB, Middle to Upper Cretaceous of WCSB Plains, Middle Devonian of Mackenzie Corridor.
Geology, Mount Merrill, Yukon Territory - British Columbia
Authors: Fallas K M , Evenchick C A
Published: November 2010

The Mount Merrill map area is situated at the southern end of the Franklin Mountains in a foothills physiographic setting. The geology of the area is characterized by sedimentary strata of Late Devonian to Early Cretaceous age, exposed in a series of
asymmetrical box or kink folds whose geometry is controlled largely by the competence of the Carboniferous Mattson Formation. West-verging folds are locally cut by west-verging thrust faults of minor displacement. Interference of differing fold trends creates local culminations within the map area
and introduces an en echelon offset of structures at the regional scale. The Beavercrow, Merrill and Babiche anticlines form one such en echelon set. Stratigraphic refinements include the local recognition of the informal Tika formation above the Mattson Formation and the assignment of Triassic
strata to the Grayling and Toad formations. The Lower Cretaceous Chinkeh Formation found on adjacent map areas is inferred to be present at the base of the Garbutt Formation but was not directly observed within the Mount Merrill area.

Published: November 2010

A description of petroleum resource potential for all sedimentary strata in the northern mainland of Canada is presented in this open file. The study area includes the Interior Platform of Northwest Territories, Beaufort-Mackenzie Basin, Northern Foreland Belt
and Northern Yukon Fold Complex in Northwest Territories and Yukon. Very conservative estimates of total resource endowment in the Interior Platform are 1.22 x 109 m³ and 1.56 x 10¹² m³ of in-place oil and gas, respectively. Very high petroleum potential is expected to occur in the subcrop
extent of Cambrian sands in the Colville Hills area, the Kee Scarp reef fairway near Norman Wells, and on the barrier and in the back-barrier of Presqump;gt;'ile barrier complex in the south. The greatest number of discoveries and potential in the northern mainland occurs in the Beaufort-Mackenzie
Basin, where total resource estimates are 1.13 x 109 m³ of mean recoverable oil and 3.32 x 10¹² m³ of mean recoverable gas. Gas hydrate potential in the Beaufort-Mackenzie Basin is immense (2.4 - 87 x 10¹² m³). In Liard Plateau of the Mackenzie Fold Belt, in-place resource potential for
natural gas is 2.77 x 10¹¹ m³. In Eagle Plain basin, total resource endowment is predicted to be 6.94 x 107 m³ and 1.71 x 10¹¹ m³ (in-place volumes). With respect to nation-wide petroleum potential, Beaufort-Mackenzie Basin is rated high while the remainder of the northern mainland has a low to
moderate rating.

Surficial geology, Cottonwood Canyon, British Columbia
Authors: Blais-Stevens A , Clague J J
Published: November 2010

The surficial geology of the Cottonwood Canyon map area provides a record of the late Quaternary history of central British Columbia near the centre of the former Cordilleran Ice Sheet. The map depicts a variety of sediment units of glacial and non-glacial
origin superposed on a hillshade derived from a Digital Elevation Model (DEM). From oldest to youngest, the units are bedrock, till, glaciofluvial deposits, glaciolacustrine deposits, colluvium, alluvium, and organic deposits. Till, the most aerially extensive deposit, was deposited by glacier ice
and consists of boulder- to pebble-sized clasts in a matrix of sand, silt, and clay. Till underlies north-trending drumlins that indicate ice flow to the north. Glaciofluvial deposits consist of stratified, well-sorted to poorly-sorted sand and gravel. They are associated with eskers, terraces,
and blankets. Some glaciofluvial deposits are kettled. Glaciolacustrine deposits comprise sand, silt, and clay deposited in a former glacial lake impounded by decaying ice masses. Colluvium is derived mainly from glaciolacustrine deposits that failed along river banks. Alluvium consists of fine
silt, sand, and minor gravel deposited along modern streams after deglaciation. Organic deposits include peat and organic-rich mud that have accumulated in poorly drained depressions formed in older sediments and bedrock.

Seismic shothole litholog database and GIS for the Mackenzie corridor, Northwest Territories, and northern Yukon Territory
Authors: Smith I R , Lesk-Winfield K , MacDonald L E
Published: November 2010

The Seismic Shothole Litholog Database and GIS is a compilation of 75 784 individual, augered shothole records collected during 1960s and 1970s geotechnical seismic operations, conducted along the Mackenzie corridor, NWT, and northern Yukon Territory. Compiled in
a Microsoft Access database, spatially heterogeneous shothole data (reflecting past areas of focus of petroleum exploration) extend across parts of NTS areas 85, 95, 96, 97, 106, 107, 116 and 117 (forty-nine 1:250 000 map areas in total). The shothole litholog records provide baseline,
shallow-lithostratigraphic (<20 m) and geoscience information on surficial and bedrock geology, hydrogeology, geohazards, granular aggregate resources, massive ground ice, and permafrost distribution.
The database has been designed in a manner that allows it to be easily queried. A series of companion GIS databases and shapefiles have been constructed from the shothole database. These include variably scaled drift isopach shapefiles from which the thickness of drift overlying bedrock can be
discerned, and shapefiles identifying potential granular aggregate resources, permafrost and massive ground ice distribution, geohazards, and muskeg thickness. Information rendered from these databases will benefit a wide variety of users (e.g., industry, government, communities, environmental
consultants), and applications (e.g., resource management, land use planning, environmental assessments, infrastructure development and seismic exploration).
This initial version of the database focused on the digital rendering of a large file card archive of shothole records. Future database versions and updated GIS databases will incorporate extensive (>50 000) archival and recent shothole records currently being copied from various
companies.
Processing of single-channel, high-resolution seismic data collected in the St. Lawrence estuary, Quebec
Authors: Duchesne M J , Bellefleur G
Published: November 2010

Within the framework of theAppalachian Energy project of the TargetGeosciences Initiative - Part 2, more than 3000 km of single-channel, high-resolution seismic profiles were collected with a sparker source in the St. Lawrence estuary in 2003 and 2004 to map
shallow sedimentary series (sediments and the top of the underlying bedrock). The data collected include many artifacts such as short- and long-period multiples. In order to provide, as much as possible, artifact-free sections, a processing flow was developed and applied to all 55 profiles
collected. The core of the ten-step flow is a trace-by-trace deconvolution algorithm which allows the compression of the source signature. The processed sections provide improved seismic images that allow accurate picking of key stratigraphic reflectors.
Paskapoo Groundwater Study, Part II: sandstone thickness and porosity estimations using well log data for the aquifer system in the Tertiary Paskapoo Formation, Alberta
Authors: Chen Z , Grasby S E , Hamblin T , Xiu S
Published: November 2010

Although the Tertiary Paskapoo aquifer system is the most important groundwater supply in Alberta and has been under increasing development pressure since 1970's, little public information is available with respect to the regional aquifer characteristics and the
sustainable groundwater yield of the system. To study the groundwater storage capacity and its spatial variation, digital borehole geophysical logs, such as the gamma-ray (GR) and sonic (DT) logs, collected by the oil industry for the identification and characterization of petroleum reservoirs, were
used to estimate sand content and aquifer porosity of the system in this study. A total of 220 oil industry wells, covering a large portion of the system mostly in south Alberta, were selected. This open file report provides a regional overview of the study and presents some of the aquifer
parameters within the Paskapoo aquifer system.

Digital elevation model of the Mackenzie River valley, Northwest Territories
Authors: Duchesne C , Ednie M , Wright J F
Published: November 2010

The data represent a digital elevation model (DEM) of the Mackenzie River valley, Northwest Territories, which spans from the Alberta border to the Beaufort Sea (10° of latitude). Contour lines from 1:50 000 digital map sheets (source:
<>) for the Mackenzie River valley were edge matched. A line file representing the coastline was also extracted from the waterbodies element of the NTDB and was merged with the contour lines and assigned an elevation of 0
metres. These contour lines were used to generate the DEM. To make the resulting DEM file sizes manageable, the study area is divided in 5 sections. Because of memory limitations, to generate the DEM, each section was subdivided in 5 or 6 parcels. A 30 km buffer around the parcel's boundary was
assigned while generating the DEMs with the ANUDEM algorithm in ArcINFO workstation. All contour lines inside the 30 km buffer were used and a minimum Z value of 0 metres was enforced. The resulting DEMs were trimmed by 9 km, then the parcels were mosaicked using a mean. A final step cropped the
resulting section to its appropriate neatline (with a 150 m buffer on adjacent sections). Hillshade grids were generated for each section with values of 315º for azimuth, 45º for altitude and 1 for vertical exaggeration (z). The hillshades were used to visually check the quality of the
DEM; local filtering was applied where needed. The final DEM sections are named from north to south: mcdem30a, mcdem30b, mcdem30c, mcdem30d, and mcdem30e. Their respective hillshades are named with the "hs" prefix: mcdem30a_hs, mcdem30b_hs, mcdem30c_hs, mcdem30d_hs,
mcdem30e_hs.
Field-based stratigraphic studies in the Peel Plateau, Peel Plain, and adjacent areas, Northwest Territories and Yukon

Published: November 2010

The Peel Plateau and Peel Plain are prospective hydrocarbon exploration areas that are the focus of a four-year (2005-2009), multi-agency project within the Mackenzie corridor. In 2006, research on hydrocarbon resource potential involved fieldwork on outcrop
exposures within Peel Plateau, Peel Plain, and adjacent areas of the northern Mackenzie Mountains, Mackenzie Plain, and Richardson Mountains. Data from outcrop are necessary to improve knowledge about stratigraphic and structural relationships, depositional and tectonic histories, basin evolution,
and petroleumpotential. In total, 27 stratigraphic sections were measured and more than 100 outcrop stations were examined within seven 1:250 000-scale map areas of the Northwest Territories and Yukon (NTS 96 E, 106 E, F, G, H, I, and L). More than 200 samples were collected to evaluate source- and
reservoir-rock potential, refine biostratigraphic ages of units, and
examine sedimentary petrology.
Paskapoo groundwater study part V: detailed outcrop measured sections of the Scollard, Porcupine Hills and Paskapoo formations in the Calgary region, Alberta
Authors: Hamblin A P
Published: November 2010

The Paskapoo Formation, of Paleocene age, is an important, but poorly understood groundwater aquifer in western Alberta, and is now becoming recognized as a shallow-gas reservoir. Because the Paleocene rocks represent the bedrock at surface over their area of
occurrence, and have not previously been a major hydrocarbon target, there has been little study of outcrop or subsurface data. This report briefly summarizes outcrop fieldwork, primarily detailed measured sections, in the Bow River corridor, in an east-west transect, both
within and west of the city of Calgary, where Porcupine Hills-Paskapoo rocks are intermittently exposed. The material is presented as 15 standard measured sections, with text descriptions of units, and measured paleocurrent data, which approximate a continuous succession of the strata represented
in this region. Two main facies are present: a) thick, multistoried fluvial channel sandstones with erosive bases, and b) pedogenically altered siltstones with thin sandstone interbeds and calcrete horizons. This report complements two other Open Files on outcrop sections of the Paskapoo Formation:
one on the Red Deer River (GSC OF 5535), and the other on drillcore sections of Paskapoo rocks in central Alberta (GSC OF 5537).
Detrital zircon geochronology of the Archean volcano-sedimentary sequence of the Barclay belt and the Paleoproterozoic marble-quartzite sequence of the Northern Chantrey group, Boothia mainland area, Kitikmeot region, Nunavut
Authors: Hinchey A M , Ryan J J , Davis W J , Nadeau L , James D T
Published: November 2010

The 'Boothia mainland area', in the Kitikmeot region of Nunavut, is located in the northern Rae Domain of the western Churchill Province. The area is characterized by variable deformed and metamorphosed volcano-sedimentary rocks of the Barclay belt; metaplutonic
rocks, which dominate the region; and a marble-quartzite sequence that is informally referred to as the Northern Chantrey group. Detrital zircon geochronology studies of three samples were conducted using the Sensitive High-Resolution Ion Micro Probe to constrain the timing of deposition of the
supracrustal sequences in the mapping area. Asample of psammitic schist from the volcano-sedimentary Barclay belt gave a maximum depositional age of 2764 ± 23 Ma based on the youngest detrital zircon. Two samples of psammitic schist from different stratigraphic levels within the Northern
Chantrey group gave a maximum depositional age of 2454 ± 13 Ma based on the youngest detrital zircon age.
Paskapoo Groundwater Study Part III: detailed core measured sections of the Paskapoo Formation in central Alberta
Authors: Hamblin A P
Published: November 2010

The Paskapoo Formation, of Paleocene age, is an important, but poorly-understood groundwater aquifer in western Alberta, and is now emerging as a shallow gas reservoir. Because the Paskapoo represents the bedrock at surface over its area of occurrence, and has
not previously been a major hydrocarbon target, there has been little study of outcrop or subsurface data. This report summarizes subsurface core work in central Alberta, primarily from wells located north and east of the cities of Calgary and Red Deer, where Paskapoo rocks form the bedrock surface
unit. Most of the eight cores are positioned relatively close to the outcrop edge of the Paskapoo Formation, and so only include strata from the underlying Scollard, and the lower and middle portions of the Paskapoo. The latest two cores were cut during a recent joint project between Geological
Survey of Canada and University of Calgary in 2003-2005. In this report, the information is presented as standard measured sections, with text descriptions of units. The lower Paskapoo is characterized by thick, multi-storied fluvial channel sandstones (Haynes Member) whereas the middle Paskapoo
comprises primarily thinly interbedded siltstones and sandstones (Lacombe Member). This report is meant to be complementary to two other Open Files on the outcrop measured sections of the Paskapoo of the Red Deer region (GSC OF 5535), and of the Calgary region (GSC OF 5536).
Chemistry of kimberlite indicator minerals and sphalerite derived from glacial sediments of northwest Alberta

R , Kjarsgaard I M
Published: November 2010

Plouffe et al. (2006a) reported the presence of kimberlite indicator minerals (KIMs), and sand-sized sphalerite and galena grains in glacial sediments from northwest Alberta. In this report most of the KIMs, originally identified from optical properties alone,
are now confirmed as such following detailed electron microprobe analyses. The exceptions to this are 1) fifteen grains originally classified as low Cr-diopside that are re-interpreted as KIMs because their Cr2O3 content exceeds 0.5 wt.%, and 2) one grain originally identified as chromite is
re-classified as crustal ilmenite. These new results confirm the presence of anomalous concentrations of KIMs in three glacial sediment (till) samples and suggest that an unknown kimberlitic source is reflected in the glacial sediments of northwest Alberta. Electron microprobe analyses (n=180) were
completed on 15 sphalerite grains recovered from till in the region of the sphalerite anomaly (Plouffe et al., 2006a). The sphalerite grains have an average composition of 33.4 wt.% S, 65.4 wt.% Zn, 0.7 wt.% Fe, 0.43 wt.% Cd, and trace amounts (0.3 to 0.1 wt.%) of Cu, Ag, Se, and
In which is slightly different from the sphalerite from the Pine Point deposit.
Geological relationships at Upper Arrow Lake, southeastern British Columbia: implications for the Milford and Kaslo groups
Authors: Kraft J L , Thompson R I , Erdmer P
Published: November 2010

Devonian strata correlative with the Devonian Silver Creek and Chase formations have recently been recognized beneath argillaceous Milford Group rocks on the western margin of the northern Kootenay Arc at Upper Arrow Lake. New mapping demonstrated that those
argillaceous rocks conformably overlie the Devonian units, suggesting that that component of Milford Group and overlying mafic volcanic
rocks, which had both been assigned to the Slide Mountain terrane, were deposited on Devonian continental margin strata and are therefore parautochthonous. That these units were deposited on equivalents of the Silver Creek Formation implies a stratigraphic connection to the Eagle Bay assemblage.
Detailed mapping in the vicinity of the Northeast Arm of Upper Arrow Lake characterized an assemblage of phyllite, limestone, quartzite, and greenstone that is interpreted as resurfacing of the Index Formation along the western limit of the Lardeau Group.
Pehdzeh Ki Ndeh area of interest hydrocarbon assessment summary report
Authors: Morrow D W , MacLean B C
Published: November 2010

Pehdzeh Ki Ndeh area of interest embraces parts of four physiographic regions that are characterized by distinctive subsurface geology. The Great Slave and Great Bear Plains of east-central Pehdzeh Ki Ndeh and the Mackenzie Plain of western Pehdzeh Ki Ndeh have
low to moderate potential for natural gas and low oil potential. Quantitative estimates indicate that the ultimate potential of the Pehdzeh Ki Ndeh area of interest is probably less than 0.5 trillion cubic feet of natural gas. Sandstone of the Mount Clark Formation in the Great Bear Plain is the
most prospective gas reservoir unit. Oil potential is not significant and is probably less than 1.0 million barrels.

Five Lakes area of interest hydrocarbon assessment summary report
Authors: Morrow D W
Published: November 2010

Five Lakes area of interest comprises two small areas in the western part of Great Slave Plain near the community of Jean Marie River. This area is underlain by an undeformed succession of Devonian carbonates and siliciclastics, which unconformably overlies
Precambrian strata. Devonian reef mounds of the Horn Plateau Formation are the most prospective potential petroleum reservoirs and some nearby wells had Horn Plateau gas shows. The potential for undiscovered gas in the Five Lakes area of interest is rated low to moderate. Oil potential is not
significant. Regional quantitative estimates indicate that the ultimate potential of the Five Lakes area is about 5 billion cubic feet of natural gas. The strong dependence of this estimate on the presence of Horn Plateau reefs within, or very close to, the Five Lakes area of interest indicates that
interpolation from regional quantitative gas potential estimates of even this small gas resource may be optimistic.
Hydrocarbon assessment summary report of Willow Lake, Kelly Lake, Bear Rock, and The Smokes areas of interest
Authors: Lemieux Y
Published: November 2010

The purpose of this report is to present a hydrocarbon resource potential assessment of Willow Lake, Kelly Lake, Bear Rock, and The Smokes areas of interest. The four areas examined here are located in the central Mackenzie Valley, and together cover an area in
excess of 1000 km2. The central Mackenzie Valley is underlain by a succession of folded and thrust-faulted resistant Paleozoic carbonate and siliciclastic rocks overlain by a thin veneer of Mesozoic and Tertiary clastic units; some of the units are prospective for oil and gas. Two exploration
wells have been drilled within Willow Lake area of interest. No exploration wells have been drilled within Kelly Lake, Bear Rock or The Smokes areas of interest. This report suggests that the overall petroleum potential of Willow Lake, Kelly Lake, Bear Rock, and The Smokes areas is probably low to
moderate.

The objective of this report is to present a hydrocarbon resource potential assessment of Mountain River, Keele River, Ravensthroat/Redstone River, and Drum Lake areas of interest. The four areas examined here are located in the Mackenzie Mountains, and together
cover an area in excess of 25,000 km2. The geology of the Mackenzie Mountains is characterized by uplifted, faulted and folded Proterozoic, Paleozoic and Mesozoic carbonate and siliciclastic rocks. Although adequate potential source and reservoir rocks are present throughout the Mackenzie
Mountains, their overall hydrocarbon potential is low. Because much of the potential reservoirs are exposed at surface, there is an increased risk of reservoir breaching, or flushing and/or degradation of hydrocarbons by meteoritic or ground water. Much of Mountain River, Keele River,
Ravensthroat/Redstone River, and Drum Lake areas of interest have low hydrocarbon potential; the potential is higher where the areas of interest are underlain by the Plateau Overthrust play.
Preliminary report on the Triassic and Jurassic stratigraphy and paleontology of the Sinwa and Takwahoni formations near Lisadele Lake, Tulsequah map area, northwestern British Columbia

Asouthwestern outlier of the Whitehorse basin strata in central Tulsequah map area (NTS 104 K/11) includes interbedded fossiliferous conglomerate, sandstone, siltstone, and mudstone of the Lower to Middle Jurassic Takwahoni Formation (Laberge Group) that
unconformably overlies Upper Triassic limestone of the Sinwa Formation. The refined age and provenance of several episodes of coarse clastic input into the basin show that the character of the dominant clasts in the conglomerate changes upsection. Immediately above the unconformity, breccia and
conglomerate contain sedimentary clasts derived from the Sinwa Formation. Clast dominance changes to volcanic near the base of the section, plutonic (in Pliensbachian-Toarcian strata), metamorphic (in uppermost Toarcian rocks), and finally, after an interval of fine-grained sedimentation, to chert
in the Middle Jurassic strata of Early Bajocian age. The uppermost
chert-pebble conglomerate and the underlying black mudstone beds are tentatively placed in the Bowser Lake Group.
Ice-flow studies in Boothia mainland (NTS 57A and 57B), Kitikmeot region, Nunavut

Published: November 2010

Mapping surficial macroforms and glacial striations in the Boothia Mainland area of central Nunavut has unveiled a complex, four phase ice flow history. From oldest to youngest, the ice flow history consists of: Phase 1 to the north, Phase 2 to the northeast,
Phase 3 to the east, and Phase 4 to the north. Glacial transport studies established by petrographic counts of erratics indicate that all four phases had an influence on dispersal trails from up-ice bedrock sources. Erratics of Paleoproterozoic orthoquartzite were particularly useful to illustrate a
palimpsest-shaped dispersion train, wherein orthoquartzite eratics were carried more than 175 km from source. These dispersal train studies are vital for mineral exploration programs utilizing kimberlite indicator minerals, kimberlite debris, or till geochemistry in this
region.
HYBRID: a wellhead protection delineation method for aquifers of limited extent
Authors: Paradis D , Martel R
Published: November 2010

Delineating wellhead protection areas around existing wells can be difficult due to the complexity of the architecture and material that constitutes the aquifer. For example, the unconsolidated aquifers of the St. Lawrence Lowland often have a stripped shape, and
simple analytical methods alone are usually inappropriate to define the wellhead protection areas. In this context, a HYBRID method was developed. This proposed method uses field observations and/or simple analytical methods to delineate the upgradient and downgradient boundaries of the wellhead
protection areas.Asimple water balance between the aquifer recharge rate and the pumping well discharge rate serve to constrain the size of the elliptic wellhead protection areas. Not only is the method useful for the delineation of the zone of contribution, but also for the zone of
travel.
Geology of Hans Island and adjacent parts of Kennedy Channel, northwest Greenland (Kalaallit Nunaat) and northern Nunavut (Canada)
Authors: Harrison J C , Dewing K , Mayr U
Published: November 2010

Hans Island lies in the middle of Kennedy Channel, a segment of Nares Strait which is the submarine valley that lies between eastern Ellesmere Island in northernmost Nunavut and coastal northwest Greenland. This island is the exposed part of a
glacially-sculptured and, mostly, submerged bedrock hill that rises to a height of 168 m above sea level from channel sea floor that locally exceeds 400m depth. Other partly or entirely submerged bedrock hills are located elsewhere in Kennedy Channel. The largest and closest of these is associated
with Franklin Ø which is located 20 km southwest of Hans Island.

Bedrock of Hans Island is unmetamorphosed fossiliferous limestone, laid down in warm shallow seas during mid-Silurian time, about 430 million years ago. These are stratified rocks, about 195 m thick, best exposed in cliffs along the south coast but also on the tilted upland surface of the island.
The island is ice-scoured and draped in a discontinuous till veneer comprised of locallyderived limestone gravel and some gneiss and granitoid material, almost certainly derived from a former north northeasterly-flowing valley glacier originating in Greenland.

Marine geophysical profiles from the Hans Island region indicate that much of central Kennedy Channel is underlain by gently north-west dipping bedrock strata, not unlike that exposed on western Washington Land in northwest Greenland. The thickness of undeformed strata, down to the base of the Lower
Cambrian, probably exceeds 3000 m. In contrast, northeastern Ellesmere Island is a Cenozoic mountain belt featuring giant mapscale folds in deformed Neoproterozoic to Devonian and Paleogene strata and a Paleogene array of sinistral strike slip and reverse faults. Commodities that might be considered
for exploration purposes in the Hans Island and central Kennedy Channel region include sediment-hosted zinc, lead, copper and hydrocarbons. However, the potential for a commercial resource is not considered significant.
Correlation to Middle to Upper Triassic strata in the Wembley area of west-central Alberta

Published: November 2010

Correlation of Middle to Upper Triassic strata in the Wembley area of west-central Alberta illustrate the stratigraphic setting of "anomalously thick sandstone bodies (ATSBs)" in the Doig Formation as well as confirming the presence of an unconformity between
Middle and Upper Triassic strata.
Seismic stratigraphy of the lower St. Lawrence River estuary (Quebec) Quaternary deposits and seismic signature of the underlying geological domains
Authors: Duchesne M J , Pinet N , Bolduc A , Bédard K , Lavoie D
Published: November 2010

The lower St. Lawrence River estuary is a narrow Quaternary basin filled with several stacked sedimentary units. Recently, high-resolution seismic-reflection surveys conducted in the lower St. Lawrence River estuary permitted identification of eight seismic units
overlying three lithotectonic domains with different seismic signatures. Units 1 and 2 have highly variable thickness and fill most of two major bedrock depressions that exist in the study area. Unit 3 is present over the entire lower St. Lawrence River estuary basin, partly infilling ponded basins
found on the shoulders of the estuary. Units 4 and 5 have a more constant thickness, suggesting that they were deposited in a hemipelagic setting. Units 6, 7, and 8 result from local processes like the sedimentation of submarine fans, mass-wasting deposits, and contourite drifts occurring along the
flanks of the Laurentian Channel. The thickness of the Quaternary succession shows a strong correlation with the bedrock topography, indicating that the lower St. Lawrence River estuary was an effective sediment trap.
Géologie des formations en surface et histoire glaciaire, Rivière Harricana, Québec

Published: November 2010

Le feuillet cartographique de Rivière Harricana constitue l'une des dix cartes à l'échelle 1/100 000 de la série des cartes des formations en surface de l'Abitibi québécois. Sous le vocable "Abitibi" sont regroupées six cartes
qui s'étendent au territoire de la municipalité de
la Baie-James et quatre qui couvrent la majeure partie de quatre municipalités régionales de comté (MRC) de l'Abitibi. En plus de montrer la répartition des dépôts superficiels, ces cartes indiquent les diverses directions d'écoulement glaciaire, la limite de
submersion glaciolacustre, la répartition des sillons d'icebergs, des dépressions annulaires (anneaux forestiers) et les positions probables de formes profilées enfouies. Dans des blocs occupant la partie supérieure du feuillet, des cartes thématiques accompagnées de
courts textes descriptifs ainsi que de figures et de photos pertinentes abordent de façon succinte l'histoire glaciaire de la région. Les thèmes choisis traitent de la géologie du substratum rocheux et des propriétés magnétiques de celui-ci pour le feuillet, et des
écoulements glaciaires et de leur ordre de succession, du transport glaciaire et de la submersion glaciolacustre pour l'ensemble des dix cartes. La stratigraphie des dépôts quaternaires, illustrée par une colonne synthétique, montre que ceux-ci ont été mis en place
selon une séquence logique et prévisible, qui permet l'application rationnelle des méthodes d'inventaire et de prospection. Des photographies prises sur le terrain complètent la description des unités cartographiques de la légende et une liste de références
présente les travaux jugés les plus pertinents pour le feuillet. En fournissant une vision globale sur l'histoire glaciaire de l'ensemble de la région entourant le feuillet de Lac Matagami, nous espérons en faciliter la compréhension et mettre en évidence les liens
entre les dix cartes de la série. La présentation des grands traits de l'histoire glaciaire et des textes descriptifs a été conçue de façon à atteindre le plus grand nombre possible d'utilisateurs.
