Geology, Blanchfield Lake, Baffin Island, Nunavut
Authors: St-Onge M R , Scott D J , Corrigan D
Published: November 2010

The purpose of this database is to provide a complete, digital, internally consistent, and georeferenced collection of spatial data that will assist interested parties in mineral exploration, environmental studies, land use planning, and other investigations
requiring up-to-date earth sciences information.

The geoscientific data included, and the bedrock geological interpretations presented, are the result of a third and final summer of field work (July and August 2002) of a three-year, integrated geoscientific project in the central portion of Baffin Island which is supported by the Geological Survey
of Canada and the Polar Continental Shelf Project (Earth Sciences Sector, Natural Resources Canada) in partnership with the Canada-Nunavut Geoscience Office (Iqaluit, Nunavut). Subsequent databases and geoscientific interpretations released by the Central Baffin Project will feature results derived
from continued bedrock compilation and synthesis activities, as well as publications stemming from surficial mapping, 3D structural modelling, teleseismic, magnetotelluric and gamma-ray surveys, geochronological and geochemical sampling, and 9 BSc, 5 MSc, and 2 PhD theses being completed in the
greater project area.
A GIS dataset of geological features for the Brown Lake map area (95 C/7), Yukon Territory
Authors: Khudoley A K
Published: November 2010

The geological map and database are derived from regional mapping in the Brown Lake (NTS 95C/7) 1:50 000 scale map area, as part of the Geological Survey of Canada's Central Foreland NATMAP project. Geological features represented by attributed points, lines, and
polygons have been compiled into a GIS dataset suitable for stand-alone use, or integration with other data sets. User-defined attributes provide traditional geological map information with greater detail and enhancements such as explicit orientation data and lithologies.
The Brown Lake map area is situated to the west of the southern end of the Franklin Mountains in a foothills physiographic setting. The geology of the area is characterized by sedimentary strata with the predominance of terrigenous rocks of Late Devonian to Early Cretaceous age. Three subparallel
unconformities at the base of Permian, within Permian, and at the base of Triassic successions are recognized. Lower Cretaceous rock units overlie Triassic and Permian rock units with low-angle unconformity at the base. Predominant structures are regional-scale, north-trending box-like folds with
narrow limbs and wide hinge zones with sub-horizontal bedding. Locally, the east limb of the Fantasque Syncline is cut by west-verging thrust fault of minor displacement. Stratigraphic improvements include recognition of the informal Permian Tika map unit above the Mattson Formation, assignment of
Triassic strata to the Toad Formation, and local recognition of the Chinkeh Formation at the base of Lower Cretaceous succession.

Le feuillet cartographique de Lac Matagami 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 a 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.
SHRIMP U-Pb detrital zircon geochronology of Athabasca Group sandstones, northern Saskatchewan and Alberta
Authors: Rayner N M , Stern R A , Rainbird R H
Published: November 2010

Detrital zircon geochronology was conducted on five sandstone units from the Athabasca Group of northern Saskatchewan and Alberta using the SHRIMP II ion microprobe. In ascending stratigraphic order, the youngest zircons from the Fair Point Formation and from
members B and D of the Manitou Falls Formation yielded maximum ages of deposition of 1810 ± 15 Ma, 1819 ± 21 Ma, and 1814 ± 23 Ma,
respectively. The overlying Wolverine Point Formation yielded three zircons with a mean age of 1662 ± 17 Ma. Among the five samples studied, these zircons are the youngest encountered and provide the best constraint on the maximum age of the upper part of the Athabasca Group. The youngest
zircons from the uppermost Douglas Formation range in age from 1775 to 1765 Ma. The key age modes identified from the five samples are 1780 Ma, 1850 Ma, 1900 Ma, 2530 Ma, 2580 Ma, 2610 Ma, and ca. 2700 Ma.

Surficial geology, McKellar Bay, Baffin Island, Nunavut
Authors: Hodgson D A
Published: November 2010

This surficial materials map is one of seven describing central and western Meta Incognita Peninsula as well as the head of Frobisher Bay, at the southeast extremity of Baffin Island. The communities of Iqaluit and Kimmirut lie within these seven maps. Weathered
to unaltered rock is the most extensive surficial material; it is divided on the basis of decreasing susceptibility to weathering into five units. Mappable till covers a minority of the map area; elsewhere, pockets of thin till overlie bedrock. The single till unit is clast supported with an acidic
silty sand matrix, though a silty matrix-supported till is discontinuously present on the southeast coast. Clasts are boulder and cobble Shield rocks of local origin. Thickest till is in the Frobisher Bay Moraine System (FBM) which is composed of multiple end moraine ridges on the flanks
of Frobisher Bay (linear on the north side, where ice pushed upslope, convoluted on the south side in ridges and valleys) and a thick till belt farther west (looping down the regional slope). The area southeast of Markham Bay also has a thick till cover.
Subglacial and proglacial aqueous deposits and landforms are prominent locally. The most common are sand and gravel subaerial glaciofluvial deposits concentrated in the FBM adjacent to Frobisher Bay; farther west, valley trains follow preglacial valleys to Hudson Strait. Raised glaciomarine deposits
in the form of proglacial deltas are present where FBM intersects coasts (Frobisher and Markham bays) and where valley trains terminate. Thick, silty marine deposits are patchy around Frobisher Bay; on the southeast Hudson Strait coast calcareous silty till indicates source ice was in the strait.

There is no terrestrial record of glaciers predating the last (Late Wisconsin) glaciation other than cirques. Striations, rock and till drumlins and till lineations indicate last glacial ice flowing from local, Foxe Ice Dome, down-Hudson Strait and cross-strait sources. The dominant flow was
generally southeast across Baffin Island from the Foxe Ice Dome and this was also responsible for the late glacial readvance into the head of Frobisher Bay (to FBM).

Fluid evolution and pressure regimes in the Campbell - Red Lake gold deposit, Red Lake mine trend, Red Lake, Ontario: fluid-inclusion evidence for a protracted, highly dynamic hydrothermal system
Authors: Chi G , Dubé B , Williamson K
Published: November 2010

Fluid inclusions were studied in quartz grains assigned to pre -, syn -, and post - main-stage gold mineralization (Q1, Q2, and Q3) in the Campbell-Red Lake gold deposit. Carbonic fluid inclusions, dominated by CO2 with variable amounts of CH4 andN2, are
predominant in all stages. Aqueous inclusions are rare in Q1 and Q2, but common in Q3. Using homogenization temperatures of 350º, 390º and 320ºC for
aqueous inclusions in Q1, Q2, and Q3 respectively, fluid pressures of up to 2706, 2574, and 1000 bars (corresponding to lithostatic loads of 10.2, 9.7 and 3.8 km) have been obtained from the isochores of carbonic fluid inclusions. Large fluctuations in fluid pressure within individual stages are
attributed to variation between lithostatic and subhydrostatic regimes in relation to structural evolution. The extreme scarcity of aqueous inclusions in Q1 and Q2 suggests a 'dry' (water-deficient) carbonic-rich hydrothermal system with CH4 and N2, whose gold transporting capacity needs further
examination.
Preliminary interpretations of mid-Jurassic volcanic and sedimentary facies in the east Telegraph Creek map area
Authors: Simpson K A , Nelson J L
Published: November 2010

On the basis of regional-scale and reconnaissance mapping, strata similar in age and character to those hosting the Eskay Creek precious-metal-rich, volcanic-hosted massive sulphide deposit are considered to project northward into the east Telegraph Creek map
area. Detailed volcanic- and sedimentary-facies mapping in that area in 2003 has identified a variety of subaqueous volcanic and sedimentary facies of probable Lower or Middle Jurassic age. Subaqueous volcaniclastic and nonvolcanic clastic rocks dominate the field area. Coherent volcanic and
associated volcaniclastic facies occur in several areas and are considered to indicate proximity to volcanic centres. The presence of marine fossils, sediment gravity-flow deposits, and pillow basalt provide evidence for a submarine environment; the lack of shallow-water sedimentary structures
indicate that the environment of deposition was below wave base.
Transport and attenuation of arsenic, cobalt and nickel in an alkaline environment (Cobalt, Ontario)
Authors: Percival J B , Kwong Y T J , Dumaresq C G , Michel F A
Published: November 2010

Understanding the behaviour of arsenic in natural waters is important because arsenic and its compounds are toxic to humans and aquatic organisms. The Cobalt area, once renowned for its bonanza silver deposits, is now characterized by numerous deposits of
arsenic-rich tailings, waste rock piles and remnant historic mine workings. Very limited mitigation has been undertaken since the cessation of mining. Thus, despite its slightly alkaline character, the surface drainage system continues to be contaminated from leaching of the widespread mine wastes.
This Open File documents the transport and attenuation of arsenic and associated elements in the surficial environment from mine wastes (tailings and waste rock) through surface waters to wetlands of the Farr Creek drainage basin in Cobalt, Ontario.
Pontypool 'golden spike' borehole digital data compilation: sedimentology and geophysical data
Authors: Russell H A J , Sharpe D R , Hunter J
Published: November 2010

The Pontypool borehole was drilled by Golder and Associates for the municipality of Kawartha Lakes. The Ontario Ministry of Environment provided funding for the initial drilling and geophysics. The borehole was terminated in bedrock at ~171 m depth and
core was collected in 114 runs. The GSC completed bed-by-bed sediment logging of the core, grain size and total organic carbon analysis (TOC), and downhole geophysical logging. The core description consists of 405 individual units ranging from 0.01 to 1.2 m thickness with an average thickness of
0.35 m. The core description is presented in three formats, a typed entry of the logging sheet in MSExcel, a synthesized MSExcel spreadsheet for entry to the database, and the MSAccess database. The core is also documented by 739 photos that have also been combined in 113 photo mosaics. Grain
size analysis was completed on 192 samples and TOC analysis on 241 samples. Downhole geophysical logs on this CD include: conductivity, natural gamma, magnetic susceptibility, temperature, and p-wave. Data files are presented in the following, text, MSExcel, MSAccess, Adobe Acrobat, and jpg file
formats. The GSC data forms the main content of this CD-ROM. The data has been summarized on the poster "Pontypool 'Golden Spike' Borehole Data Compilation" published as GSC Open File 1746. This Open File is also on this CD as an Adobe Acrobat pdf file.

This Core is located within the Pontypool wedge of the Oak Ridges Moraine. It intercepts Oak Ridges Moraine to a depth of ~96 m and is predominantly silt and sand. Below this depth is 74 m of Lower sediment that is predominantly diamicton and silt - clay. Bedrock was intercepted at ~169
m depth. The Oak Ridges Moraine sediment has infilled and buried a tunnel channel.
Stratigraphy of the Mesoproterozoic Society Cliffs Formation (Borden Basin, Nunavut): correlation between northwestern and southeastern areas of the Milne Inlet Graben
Authors: Turner E C
Published: November 2010

The existing stratigraphic nomenclature does not adequately portray the complex facies architecture and temporal relations in the upper Arctic Bay Formation - Society Cliffs Formation interval in the Milne Inlet Graben. The Society Cliffs Formation in the
southeastern area is a carbonate ramp divided into lower and upper members on the basis of upward-declining terrigenous content. The lower member grades westward into basinal shale belonging to the upper Arctic Bay Formation, and, in scattered locations, deep-water carbonate mounds that formed
topographically pronounced edifices rising from the basin floor. The upper member passes westward to deep-water carbonate laminite, which is the host rock for most base-metal showings in the region and for the Nanisivik orebody; although deep-water mound growth had ceased, the relict topography of
mounds remained significant throughout laminite deposition. These temporal equivalencies should be taken into consideration in matters concerning basin evolution, fluid flow, and diagenetic patterns in the Milne Inlet Graben.
Wisconsinan stratigraphy at northern margin of Strait of Georgia, southern Cortes Island and vicinity, British Columbia
Authors: Trettin H P
Published: November 2010

About 130 m of Wisconsinan strata, exposed on the northern margin of the Strait of Georgia record climate-controlled, cyclical, predominantly marine deposition. Position below sea level of the base of the sediments (>80min a well) is attributed to
pre-Wisconsinan glacial erosion within the strait. The early Wisconsinan Semiahmoo Glaciation produced advance deposits (Cortes Sand, new formation) and glaciomarine sediments and till (Marina Island Diamict, new). The middle Wisconsinan Olympia Nonglacial Interval is represented by the upper member
of the Cowichan Head Formation, which unconformably overlies the diamict. The late Wisconsinan Fraser Glaciation generated advance deposits (Quadra Sand); glaciomarine sediments (Mansons Landing Diamict, new); inferred till and glaciomarine sediments represented by boulder lag only; subaqueous delta
sediments; and again inferred glaciomarine sediments, winnowed to boulder lag during the isostasy-driven final emergence.
Scotian Shelf regional surficial geology compilation
Authors: Fader G B J , Lynds T , Miller R O , Parrott D R , Hynes S , Sherin A
Published: November 2010

This compilation is a GIS-ready data set of a compilation of the surficial geology of the Scotian Shelf from Georges Bank to the Laurentian Channel. The data set defines the boundaries of surficial geology map units (formations) of Quaternary age. It was
digitized from previously published paper maps of the Geological Survey of Canada. Accompanying the original paper maps were scientific reports that described mapping methods, control, detailed descriptions of the map units, applications and references relating to a systematic regional mapping
program that was conducted by the GSC over a period of approximately 20 years. Five surficial sediment units (formations) were mapped and a chronology of geological history was proposed. The most important contribution of these maps to an understanding of the geology of the continental shelf is
their portrayal of sediment type, classification and distribution in a conceptual formational model framework.

The Committee Bay belt is a 600 km long belt of northeast-striking, Archean supracrustal rocks and granitoid plutons that form part of the
Rae Province in central Nunavut (Fig. 1). The Archean supracrustal rocks of this belt belong to the Prince Albert group (PAg; Heywood, 1961), and are host to a number of gold and base metal occurrences. This map is a product of the 2000-2003 Targeted Geoscience Initiative that was instigated by the
Canada - Nunavut Geoscience Office in partnership with the Geological Survey of Canada and university researchers, as a stimulus for mineral exploration of this remote area. The project involved an aeromagnetic survey, helicopter-supported, 1:100,000 scale bedrock and surficial mapping of NTS map
sheets 56K, 56J (north), 56O (south) and 56P, supporting geoscience studies and a drift prospecting survey. The aeromagnetic survey covered 85,300 line km and was flown along 400 m spaced, northwest - southeast flight lines (perpendicular to strike) on a pre-calculated drape surface with a mean
terrain clearance of 150 m (Kiss et al., 2002a-g). The results of the bedrock mapping and related petrological/structural studies are presented in the following: 1) Laughland Lake area (56K) - Johnstone (2002), Johnstone et al. (2002), MacHattie (2002) and Sandeman et al. (2001a-c); 2) Walker Lake

This map is part of a series depicting the surficial geology of Central Baffin Island. The mapping of Quaternary deposits, measurement of ice flow indicators, interpretation of glacial and post-glacial history, and geochemical sampling of the till in this area
are part of an integrated multi-component mapping project led by Marc St-Onge and supported by the Geological Survey of Canada, the Canada-Nunavut Geoscience Office, and the Polar Continental Shelf Project. Field work related to the surficial geology component was conducted in 2001 and 2002. Field
traverses and air photo interpretation provided information on the nature and distribution of surface materials shown on the map, which was constructed using 1:60,000 scale aerial photographs compiled onto a 1:100,000 scale base.
Postglacial marine deposits and marine limit determinations, inner Wager Bay area, Kivalliq region, Nunavut
Authors: Dredge L A , McMartin I
Published: November 2010

This paper discusses postglacial marine features, including raised beaches and deltas, marine plains, and wave-erosion trimlines near the marine limit. Marine-limit measurements indicate that postglacial seas regionally inundated the area to an elevation of
110min the inner part of Wager Bay, and to about 95 m west of Brown Lake. Sporadic marine-limit elevations as low as 50 m correspond to areas with
late-glacial ice. Marine shells at an elevation of 60 m yielded radiocarbon ages of about 5800 years.
Feasibility study for using high-resolution seismic methods to estimate kimberlite deposit volumes at the Snap Lake diamond mine, Northwest Territories
Authors: Snyder D , Bellefleur G
Published: November 2010

Anovel, ultra-high-resolution application of crossborehole seismology was tested at the Snap Lake diamond mine of De Beers Canada Inc. to assess whether the relatively thin kimberlite dyke that hosts the diamonds could be mapped underground with sufficient
resolution to estimate accurately its volume and to guide mining. Subsequent mining and geological mapping within the test panel demonstrated that the technique was able to map the top and bottom surfaces of the dyke and to identify ramps and pinch-outs of the dyke as well as crosscutting fracture
planes. In planning of the present test, De Beers Canada Inc. was advised to also trial two other geophysical methods beside the explosive sources used here. Comparison with higher frequency vibrating seismic and radar sources suggests that radar is the most effective technique in this specific
application.
Major Quaternary mass-transport deposits in southern Orphan Basin, offshore Newfoundland and Labrador
Authors: Campbell D C
Published: November 2010

Orphan Basin is a deep-water basin off the northeast coast of Newfoundland that is currently an area of active hydrocarbon exploration. The Geological Survey of Canada has conducted regional high-resolution seismic-reflection and seabed sampling surveys during
2003 - 2004 to improve understanding of the Quaternary geology and identify potential geohazards. Evidence of past instability includes thick, stacked mass-transport deposits on the basin floor and seabed failure scars on the continental slope. Most of the mass-transport deposition through the
Quaternary occurred in the northern part of the study area, although there has been a shift towards the northwest during the Pleistocene. Recurrence of large-scale seabed failure through the Quaternary is on the order of 75 000 - 100 000 years, but it is not clear if there is a correlation with
global sea-level change and glaciations or if the distribution is random.
Preliminary results from water-isotope characterization of groundwater, surface water, and precipitation in the Wilmot River watershed, Prince Edward Island
Authors: Liao S L , Savard M M , Somers G H , Paradis D , Jiang Y
Published: November 2010

Agricultural activity, especially the application of fertilizers, is believed to be a major source of nitrates in groundwater and surface water in Prince Edward Island. Analyses of 107 groundwater and 17 surface-water samples from 4 seasonal field operations in
the Wilmot River watershed, and 13 precipitation samples, indicate that average annual nitrate concentrations in groundwater are 6.5 mg/L N-NO3, with 22%
of domestic wells exceeding the health guideline of 10 mg/L N-NO3. Concentrations in surface water average 6.2 mg/L N-NO3, but all are below 8 mg/L N-NO3. Stable isotopes of oxygen and hydrogen help delineate interactions between precipitation, groundwater and surface water. Groundwater values fall
on or near the meteoric-water line for Charlottetown, indicating that groundwater may be derived entirely from modern local precipitation, although additional precipitation sampling is needed for confirmation. Surface waters have average isotope values similar to those for groundwater, implying that
surface water is derived almost entirely from groundwater.
A GIS dataset compilation of lead and zinc occurrences for the Targeted Geoscience Initiative project: potential for carbonate-hosted Pb-Zn (MVT) deposits in northern Alberta and southern Northwest Territories (NTS blocks 74, 84, 85)
Authors: Hannigan P K
Published: November 2010

The Targeted Geoscience Initiative project area is located within NTS 1:250 000 map sheets 74 D,E,L,M; 84 A through P; and 85 A through H in Alberta and Northwest Territories, Canada, an area that extends from Fort McMurray and Peace River (east of Fort St. John,
British Columbia) in the south to the west shore of Great Slave Lake in the north. The northeast portion of the project area is occupied by the Canadian Shield. Sedimentary host-rocks for Mississippi Valley-type (MVT) mineralization occur within the Phanerozoic wedge in the Plains and Foothills of
the Western Canada Sedimentary Basin and in the Rocky Mountains of the Cordilleran Orogen. Carbonate-hosted lead and zinc occurrences in the project area are located within the cratonic platform succession beneath the Plains of the Western Canada Sedimentary Basin. MVT deposits and occurrences are
not found in high-temperature metasedimentary rocks of the Canadian Shield. The project area also encompasses the world-class Pine Point Mississippi Valley-type lead-zinc mine-site near the southern shore of Great Slave Lake as well as subsidiary orebodies found in the Great Slave Reef property
located immediately west of Pine Point, NWT.
This GIS dataset is a comprehensive compilation of information for 822 lead and/or zinc occurrences each interpreted to represent an orebody, showing or anomaly occurring within drillhole core or cuttings, rock outcrop, lake or stream sediment or soils. In the supplementary Alberta database, there
are 89 lead and/or zinc occurrence entries.
Distribution of "anomalously thick sandstone bodies" in the Middle Triassic of the Western Canada Sedimentary Basin
Authors: Dixon J
Published: November 2010

Isolated, thick sandstone bodies in the Middle Triassic Doig Formation have been termed "anomalously thick sandstone bodies" (ATSBs) and are present in west-central Alberta and northeast British Columbia. They occur at several stratigraphic levels within the Doig
Formation, over a limited geographic area. The ATSBs tend to become younger to the west and southwest, reflecting the direction of progradation for Middle Triassic sediments. Their distribution closely parallels the Peace River Embayment, a basin-scale depression that originated in the Carboniferous
and continued to subside during the Triassic.
The ATSBs formed in translational and rotational slumps on muddy prograding siliciclastic sediment lenses during periods of relative sea-level fall. Lower and middle shoreface deposits filled in these slumps during base-level fall and were subsequently capped by a thin layer of transgressive
sandstone when sea-level began to rise.
Geological assessment of known Zn-Pb showings, Mackenzie Mountains, Northwest Territories
Authors: Dewing K , Sharp R J , Ootes L , Turner E C , Gleeson S
Published: November 2010

The Mackenzie Mountains have more than 100 Zn-Pb showings. The objectives of the 2005 fieldwork were 1) to assess showings from a wide geographic area and stratigraphic range, 2) verify the assessment files, and 3) rank the showings on exploration potential.
TIC, ART-EKWI, BEAR, ICE, KEG, RAIN, TAP, AB, and GAYNA were visited. Most of the showings are hosted in fractures with minor brecciation and very rarely, carbonate replacement. The main economic minerals are sphalerite and galena, but copper sulphide minerals are commonly present. Gangue minerals
include dolomite, calcite, quartz, barite, and fluorite. The best targets for further exploration are considered to be showings hosted in strata that were limestone (at the time of mineralization) rather than dolostone; that exhibit strong chemical interaction between the host rock and fluid
resulting in carbonate dissolution or replacement; and that have multiple generations of sphalerite and galena. BEAR, GAYNA, AB, and TIC are considered the most attractive exploration targets.

NTS map sheets. The interaction between high relief, steep slopes, heavy precipitation, complex tectonic and glacial history, and the range of surficial deposits and bedrock along the Mackenzie River valley transportation corridor has resulted in a variety of landslide types. Earth materials most
susceptible to failure are colluvial, glaciolacustrine, alluvial, and organic deposits containing discontinuous permafrost. Till and glaciofluvial outwash are the most stable earth materials. Channel migration has triggered numerous complex landslides along the Mackenzie River. Removal of
stream-side vegetation and soil also leads to retrogressive-thaw flows and slides in ice-rich terrain.

As part of the Northern Energy DevelopmentMackenzie Valley Project, an inventory of terrain, landforms, and geomorphic processes is currently being compiled for the Camsell Bend (NTS 95 J), Root River (NTS 95 K), Dahadinni River (NTS 95 N), and Wrigley (NTS 95-O)
1:250 000 scale map sheets. This work aims to provide government agencies, industry, and the public access to secure and reliable geoscience information. The regional surficial geology is being examined to improve understanding of the limits to glaciation, subglacial processes, meltwater-drainage
patterns, glacial-lake history, landslide hazards, and aggregate and groundwater resources. Outputs from this study can be used in environmental risk and impact assessments, and will provide calibration for future predictive mapping and hazard analyses in the Mackenzie River valley transportation
corridor. Other possible outcomes include the attraction of new investment and reduction of risks for exploration and development of aggregate, groundwater, and mineral resources.
Electrochemical double-layer capacitance of graphite electrodes: preliminary results
Authors: Scromeda N , Katsube T J
Published: November 2010

Spectral--induced-polarization (spectral-IP) characteristics of 12 pairs of graphite electrodes (diameters of 5.74 and 3.77 cm), used in the two-electrode system for taking electrical measurements of rock and soil samples, have been measured to determine their
electrochemical double-layer capacitances. This is a repetition of previous measurements of similar types. The purpose was to determine if specific capacitance values can be assigned to graphite electrodes so that their effect can be subtracted from the two-electrode measurements for increased
accuracy.

Electrode characteristics, represented by capacitance over electrode surface area (CE/A) and frequency-dependence coefficient (alphaE), are 1.61± 0.5 x 10-4 to 2.94 ± 0.93 x 10-4
F/cm2 and 0.23 ± 0.02 to 0.23 ± 0.07, respectively, for the pairs of electrodes with different diameters. These variations are too large to assign single values to each diameter of electrode. Nevertheless, the repeatability of individual electrode sets with previous measurements is
extremely good with almost no errors, so values can be assigned with confidence to each specific set of electrodes.
Petroleum Resource Assessment, Peel Plateau and Plain, Yukon Territory, Canada
Authors: Osadetz K G , MacLean B C , Morrow D W , Dixon J , Hannigan P K
Published: November 2010

The Peel Plateau and Plain in the Yukon is a potentially prospective petroleum province that lies north of the Mackenzie Mountains and east of the Richardson Mountains up to the inter-territorial boundary. The area contains a Lower Cambrian to Upper Cretaceous
stratigraphic succession up to approximately 4.5 km thick. Nineteen exploratory wells have been drilled within the region without economic reserves or production, but with some petroleum shows. A probablilistic petroleum resource assessment suggests that there is a significant potential for natural
gas throughout the region with a summed mean play potential of approximately 83.428 x 109 m3 initial raw gas in place (~3 Tcf) in approximately 88 pools. The largest expected pool of 3.36 x 109 m3 gas is expected to occur in Mesozoic clastic rocks of the Peel Plain. In general, petroleum
potential is inferred to decrease both westward, and with increasing depth and stratigraphic age. The small size of gas pools will be an impediment to their development because of their location. No crude oil potential can be estimated due to an inferred lack of oil-prone sources in strata of
suitable maturity. Where previous work speculated that the history of petroleum systems in the Peel Plateau and Plain was distinctive from that of surrounding regions that are suitably characterized, this work finds no justification for such a distinctive petroleum system history. The resulting
undiscovered potential is, therefore, considered to be consistent with the results of the exploration history.

In 2002, the Geological Survey of Canada began to replace stand alone strong motion instruments with new Internet Accelerograph instruments as part of the upgrade of the strong motion network in southwestern British Columbia. From 2002 to 2004, the Internet
Accelerograph instruments have recorded four minor to moderate sized earthquakes; consisting of the MW 3.9 29 November 2002 Georgia Strait earthquake, the MW 4.2 25 April 2003 Olympic Peninsula, Washington, earthquake, and two offshore Vancouver Island earthquakes (MW 5.8 15 July 2004 and MW 6.4 19
July 2004). This open file report documents the early history of the Internet Accelerograph instruments and presents processed acceleration time series and peak ground acceleration values for the 2002 and 2003 earthquakes. The shaking levels for these smaller earthquakes are at or just above the
noise level of the instruments, reaching peak horizontal ground acceleration values of 1.85 cm/s2 and 7.79 cm/s2 for the 2002 and 2003 earthquakes, respectively.
Geology, Mount Martin, Yukon Territory-Northwest, Territories-British, Columbia
Authors: Fallas K M
Published: November 2010

The Mount Martin 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 Carboniferous to Paleogene age, exposed in a series of box folds whose
geometry is controlled largely by the competence of the Carboniferous Mattson Formation. Permian strata formerly included in the upper member of the Mattson Formation have been mapped separately as the Tika formation. Upper Paleozoic and Triassic strata are overlain unconformably by Lower Cretaceous
rocks of the Chinkeh Formation and younger units. Sub-Cretaceous erosion is a major control on the distribution of upper Paleozoic and Triassic units within the map area. Paleogene conglomerate and sandstone, interpreted as representing a syn- to post-orogenic fluvial system, is locally preserved in
the La Biche River valley. The sinuous appearance in map view of major structures is largely due to en echelon linkages of smaller culminations involving interfering northeast- and northwest-trending folds. The east limb of the Mount Martin anticline is cut by a reverse or thrust fault of minor
displacement (tens to hundreds of metres). The Kotaneelee gas field produces from Middle Devonian carbonate units in a structural culmination associated with the Mount Martin Anticline.
Gamma-ray gradiometry for point-source location

Published: November 2010

A method to extract the location of a point source, from the counts obtained by two gamma-ray detectors at different distances from the source, has been developed. With two 4 litre NaI crystals at a separation of approximately 2 m from each other, only a few
seconds of data are necessary to reconstruct the distance with a precision of better than about 20%, to a 600 µCi 137Cs source, up to 10 m away.

Published: November 2010

Northeast Baffin Island, in the region of Conn Lake and Buchan Gulf, is an area having high exploration potential for precious metals, base metals, and diamonds; however, much of the region is extensively covered by thick glacial deposits that hinder traditional,
bedrock-focused exploration techniques. A better understanding of glacial deposits, transport, and history is essential to reduce exploration risk in the region. This study presents the results of fieldwork in 2005 focused on glacial deposits and complex ice-movement history (four phases are
proposed) of northeast Baffin Island. This paper provides a review of previous work; it also includes a summary of field operations and presents a glacial chronology based on geomorphology and ice-movement indicators.
Rocks and minerals for the collector: Ottawa to North Bay and Huntsville, Ontario; Gatineau (Hull) to Waltham and Témiscaming, Quebec
Authors: Sabina A P
Published: November 2010

Occurrences of minerals, rocks, and fossils are described from about 200 easily accessible localities on either side of the Ottawa River from Ottawa - Gatineau (Hull) to North Bay. They are reached by following Highway 17 in Ontario and Highway 148 in Quebec.
Most of the collecting localities are in Renfrew County, Ontario. A wide variety of minerals are found in this area, and some localities are known for the museum-type specimens collected from them. The earliest mines were the apatite and iron mines that were operated in the 1880s. Other deposits
were subsequently worked for corundum, molybdenite, zinc, celestine, garnet, pyrite, beryl, marble, limestone, feldspar, rare-element minerals, and dolomite.
Numerous former feldspar mines as well as deposits of kyanite, garnet, muscovite, niobium, and brucite occur in the Nipissing District. Some of these deposits are accessible only by boat.
The region north of the Ottawa River between Gatineau (Hull) and Waltham was formerly mined for iron, mica, feldspar, apatite, uranium, molybdenum, lead-zinc, and limestone. A dolomite deposit is currently (2005) being operated. Occurrences of brucite, pyroaurite, szaibelyite, cordierite, scapolite,
and asbestos are also known. Farther west, in the Témiscaming - Kipawa area, a wide variety of minerals include garnet, kyanite, and amazonite, and the rare-mineral suite of the Kipawa complex. In recent years, the Témiscaming area has been the scene of exploration for diamonds, and some
diamonds have been reported from a location south of Lake Beauchêne.
Minerals and/or rocks that could be used for lapidary purposes include feldspar (peristerite, sunstone), rose quartz, graphic granite, and corundum from Renfrew County; feldspar (peristerite, amazonite), jaspilite, and graphic granite from the North Bay area; peristerite and cordierite from the
Quebec side of the Ottawa River. Ordovician fossils may be collected from numerous roadcuts, rock outcrops, and quarries in the Ottawa - Pembroke and Aylmer areas.
