Earthquake damage in the Ottawa-Gatineau region between 1830 and 2008
Authors: Lamontagne M , Sheshpari M , Khan K
Published: January 2011

Based on its earthquake hazard and population, the seismic risk of the OttawaGatineau region ("the region '') ranks third in Canadian urban areas. As part of a research activity that aims at defining microseismic zoning for the region, the historical earthquake
damage was examined The available written documents were searched for iriformation on damage related to some eighteen events that were most likely to have had some impact in the region. It was found that between years 1830 and 2008, thirteen of these earthquakes reached or exceeded the Modified
Mercalli Intensity (MMI) V level (fallen smalt abjects). Being located within the Western Quebec Seismic Zone, the region was subjected to some moderate earthquakes (magnitude between 5.0 and 6.2) at less than 300 km epicentral distance. The local earthquakes of 1856, 1861, 1908, 1909, 1913, 1914,
1917, 1924, 1933, 1935, 1944 and 1983 Jal! in that category. More distant earthquakes had some impact in Ottawa in 1870, 1924 and 1925 (epicenters in the Charlevoix Seismic Zone at about 450-525 km epicentral distance), in 1929 (Attica, N Y. at about 350 km distance) and in 1988 (Saguenay region at
about 470 km distance). The impact of these earthquakes in the Ottawa-Gatineau region was assembled in a database. For each earthquake, the database provides a description of damage together with ifs geographic coordinates, ifs corresponding MMI and the supporting document as scanned images.
Historically, certain wards sustained higher levels of ground motions due to moderate to large earthquakes.We found that the 10-50 m thick basin centered on the Museum of Nature had most instances of MMI VI and VIL In contrast, areas with thin veneer of unconsolidateddeposits, such as the Parliament

Published: January 2011

The hydrocarbon potential of the northern mainland sedimentary basin is the focus of a Northern Energy project under the Secure Canadian Energy Supply program of the Geological Survey of Canada (GSC). The main objective of this multidisciplinary study is to
assess the hydrocarbon resource potential of the underexplored Mackenzie Corridor using quantitative and qualitative geoscience data. The petroleum assessment approach developed by the GSC requires the definition of exploration petroleum plays and compilation of reservoir parameters, such as
distribution, size, and number of prospects. The present report compiles individual shapefiles outlining 19 established-immature and conceptual exploration plays located in the Mackenzie Valley and Mackenzie Mountains that are the focus of the GSC petroleum assessment study. A series of companion
shapefiles identifying individual prospects have been constructed from available geophysical maps and include information such as the size, number, distribution, and vertical closures of the prospects. Prospect statistics presented in this report are based on 215 geophysical (time and depth
structure, isopach) maps generated by the petroleum industry. This GIS compilation includes lines, polygons, attributes and raster images representing faults, exploration plays and associated prospects, geophysical maps and associated footprints. Results are presented using ArcReaderTM software
which allows the user to build maps by selecting appropriate layers.
Triassic stratigraphy in the subsurface of the plains area of Dawson Creek (93P) and Charlie Lake (94A) map areas, northeast British Columbia
Authors: Dixon J
Published: January 2011

Triassic strata in the plains of map areas 93P and 94A thicken from about 325 m in the northeast to over 1100 m in the southwest, and comprise the Montney, Doig, Halfway, Charlie Lake, Baldonnel, and Pardonet formations. The Montney, Doig, and Halfway formations
are predominantly siliciclastic, and include shale, siltstone, and sandstone beds. Charlie Lake strata consist of interbedded shale, dolostone, anhydrite and sandstone, with some locally preserved salt beds. Dolomitic limestone to calcareous dolostone is present in the Baldonnel Formation and
calcareous shale to argillaceous limestone make up the Pardonet Formation.
Montney, Doig and Halfway strata represent a series of westerly to southwesterly prograding transgressive-regressive sequences, deposited as marine-shelf to shoreface beds. Charlie Lake strata are dominated by lagoonal to sabkha-type deposits, whereas the Baldonnel and Pardonet formations are the
open-marine deposits of a carbonate shelf.
A number of basin-scale unconformities are present in the Triassic succession, cutting down to the east. These are interpreted as the result of basin-margin uplift caused by fault activity. Most of these unconformities have been recognized previously, but one identifi ed in the upper part of the
Charlie Lake Formation may be equivalent to the Jedney unconformity that was fi rst recognized in the Foothills. Also, correlations clearly show that the base of the Charlie Lake Formation is a major unconformity.
Stratigraphy and Late Pleistocene-Holocene history of Effingham Inlet, B.C., results from MONA core MD02-2494 and GSC freeze cores

Published: January 2011

The sedimentary record of Effingham Inlet, British Columbia, Canada (Appendix 1) is contained in: a 40.9 m giant (Calypso) piston core (MD02-2494; 49° 04.28 N/ 125° 09.55 W) raised from 120 m water depth in the inner basin, in June 2002, during the
2002 MONA (Marges Ouest Nord Américaines) campaign aboard the French ship RV Mariane Dufresne, and in four Geological Survey of Canada freeze cores (TUL99B04,VEC007-FC01, VEC007-FC02 and VEC007-FC03) which contain the surface sediments and were also raised from 120 m water depth in the inner
basin in October, 1999, and April, 2005, from the CCGS John P. Tully, and the CCGS Vector . The piston core MD02-2494, spans from 14,000 14C yr BP (16,700 cal yr BP) to about nine centuries before present, and the freeze cores represent from ~ AD 1992 to ~ 850 y BP.

These cores archive changes in sedimentation (Table 1)(Appendix 1 and 2) and relative sea-level immediately following deglaciation of the Late Wisconsin Fraser Glaciation, which peaked about 15,000 14C yr BP. The presence of the Mazama Ash in the MD02-2494 piston core, anchors a detailed
chronology (Fig. 1) based on forty-nine radiocarbon dates and seven Pleistocene paleo-magnetic secular variation correlations. Diatom assemblages (Table 2) identify a marine-freshwater transition in the basin, which occurred 11,631 14C yr BP (13,503 cal yr BP). At this time a bedrock sill,
presently at 46 m depth, was briefly exposed as sea-level fell. The relative sea level rose again during isostatic crustal adjustments, with a brackish-freshwater-full marine transition at 9,851 14C yr BP (11,165 cal yr BP). These data constrain a new sea-level curve for the outer coast of
Vancouver Island covering the past 12,000 14C yr BP (14,000 cal y BP) providing new information on the nature of deglaciation along the west coast of Canada, and informing interpretations of regional paleoceanographic records, and mantle viscosity models.

Published: January 2011

Triassic strata in the Beatton River area (map-area 94H) of northeast British Columbia are described and characterized largely through a series of stratigraphic cross sections and isopach maps. The Montney, Doig, Halfway, Charlie Lake, and Baldonnel formations
are present, although the latter only occurs in the south-westernmost corner of the map-area. Hydrocarbons, mostly in the Halfway Formation, are an important economic asset in this part of British Columbia.
Landslide susceptibility maps of the Sea to Sky Corridor, British Columbia - a qualitative approach
Authors: Blais-Stevens A , Kung R
Published: January 2011

Historically, the Sea to Sky Corridor has witnessed 155 reported landslide events in the last 154 years. As part of the Public Safety Geoscience Program at the Geological Survey of Canada, a preliminary landslide susceptibility mapping activity was undertaken.
The resulting maps are presented as work-in-progress. The method used was a qualitative parametric approach based on the available landslide inventory and baseline information (Journeay and Monger, 1998; Riopel et al., 2006; Blais-Stevens, 2007; 2008abc; Blais-Stevens and Septer, 2008; Couture and
Riopel, 2008). We divided the landslide susceptibility thematic mapping activity into producing two separate maps based on the more frequent types of landslides in the area and the fact that the parameters causing these types of landslides are very different from one another. One landslide
susceptibility map was created for rock falls/rock slides and the other, for debris flows. In each map, a series of information layers (Fig. 1) was compiled from available documentation and/or derived from DEMs (Riopel et al., 2006; Couture and Riopel, 2008). From this information, a parametric
equation was defined where the information layers served as parameters with each parameter being given a weight. The units within each layer of information were also given a rating (See examples of rating in Tables 1 and 2). The resulting equation gave a Susceptibility Index (SI) ranging between 0-1
for each (25 m x 25 m) pixel. For the final products, SI units were divided into four colour-coded categories, from Low (green), Medium-Low (yellow), Medium-High (orange), and High (red).
North American Soil Geochemical Landscapes Project (NASGLP): Database of GRTS sample sites with notes on the sampling design and site selection procedure
Authors: Garrett R G , Kettles I M
Published: January 2011

The North American Soil Geochemical Landscapes Project is a tri-national initiative between the United States, Canada and Mexico. It was established to develop a useful set of soil geochemical data for North America generated using a consistent set of protocols.
It involves collecting samples at a 40 km spacing and will result in more than 10 000 samples for North America, including more than 6 100 for Canada.
In 2006, a panel was convened at the U.S. Geological Survey in Denver to finalize the sampling scheme for continental coverage. The choice of a geographically based stratified random sampling plan was confirmed. The consensus was to implement the US-EPA Generalized Random Tessellated Stratified
(GRTS) design procedure to determine the locations of potential sample sites.
Detection of decadal and interdecadal oscillations and temporal trend analysis of climate and hydrological time series, Canadian Prairies

Published: January 2011

To better understand the natural modes of discharge from the Athabasca River and perform an appropriate trend prediction for the sustainability study of the oilsand development in Alberta, long term instrumental records of annual river discharge, temperature, and
precipitation time series from Canadian Prairie provinces were collected and analyzed for decadal and inter-decadal oscillation. Three types of methods, auto-correlation, composite method and spectral analysis, were applied to extract the long-term natural variation. Synthetic time series,
consisting of known periodic components of different cycle length and magnitude, mixed with linear trend and red noise, were simulated and examined to help gain a better understanding of the behaviours of the quasi-periodic variation in the acquired real time series.

Published: January 2011

Glacial history studies and analysis of heavy mineral separates from glacial sediments (till and eskers) were undertaken in theBoothia mainland area of central Nunavut. Mapping of surficial macroforms and glacial striae has shown a complex, four phase ice-flow
history. From oldest to youngest, the ice-flow history entails: Phase 1 to the north, Phase 2 to the northeast, Phase3 to the east, and Phase 4 to the north. Late-stage, localized ice-flows were determined in some areas, especially around the Harrison Uplands. All of the regional ice-flow phases
impacted on the final distribution of glacial erratics in till, but with varied influence, wherein Phase 2 to the NE and Phase 4 to the N in the southern part of Boothia mainland were the most significant glacial dispersal events. During Phase 2, glacial transport distances of greater than 100 km
were determined for Paleozoic carbonates and Paleoproterozoic members of the Chantrey Group siliciclastic (pelites, orthoquartzites), and at least 20 km for the Paleoproterozoic marble member of the Chantrey Group. Kimberlite indicator minerals (including mantle ilmenite, forsterite, Cr-diopside,
eclogitic and peridotitic (G9) garnets, chromite, perovskite and lyndsleyite) and visual gold grains were found in glacial sediments. Prospective zones for kimberlites or gold mineralization are outlined herein from heavy mineral analysis and knowledge of the ice-flow
history.
Halifax Harbour extreme water levels in the context of climate change: scenarios for a 100-year planning horizon
Authors: Forbes D L , Manson G K , Charles J , Thompson K R , Taylor R B
Published: January 2011

A Halifax Harbour Plan is being developed within the context of the 25-year Regional Municipal Planning Strategy in the Halifax region of Nova Scotia. This strategy recognizes the importance of climate change and the need for a precautionary approach to minimize
negative impacts of rising sea level. Airborne LiDAR data were acquired in 2007 to produce a high-resolution digital elevation model (DEM) as a basis for mapping flood limits. The selection of flood levels for adaptation planning required an understanding of present and future sea-level rise (SLR),
vertical land motion, extreme water levels (combined tide and surge), harbour seiche and wave runup. Relative sea level in Halifax Harbour has risen at 3.2±0.13 mm/a since 1920 through a combination of regional subsidence (1.6±0.3 mm/a) and local SLR (~1.6 mm/a). Scenarios of future
extreme water levels were developed using (1) current local SLR, (2) the upper limit of the 2007 IPCC projections, and (3) a higher projection based on a growing scientific consensus that the IPCC upper limit may have been overly conservative. These projections of SLR (0.16, 0.59, and 1.3 m over
~100 years) were combined with regional subsidence and extreme water levels for 2-, 10-, and 50-year events derived from a generalized extreme values distribution of annual extreme water levels in Halifax Harbour. The resulting water levels were applied to the LiDAR DEM to visualise the extent
and depth of flooding for each event. A plausible upper limit with very low probability was developed by superimposing the record storm surge on the highest tide with a sea-level rise of 1.3 m. A buffer ranging from 1 to 2 m was considered to account for observed values of seiche and wave runup in
various parts of the harbour. This study provides the scientific basis for a set of plausible scenarios for a 100-year planning horizon, but the choice of water level for planning purposes is a policy decision.

Petrology and Mineralogy of Lower Cretaceous sedimentary rocks, Dauntless D-35 well, Scotian Shelf
Authors: Pe-Piper G , Piper D J W
Published: January 2011

The sedimentary petrography of the Lower Cretaceous (2160 - 3600 m) in the Dauntless D-35 well has been studied from cuttings samples and one short conventional core. The 3.5 m long conventional core was logged sedimentologically and sampled for petrographic thin
sections. 37 cuttings samples were studied in detail and a "heavy mineral" fraction was separated. Detrital minerals diagnostic of provenance were analysed by electron microprobe and their chemical composition compared with elsewhere in the Scotian basin and with bedrock in the hinterland.
Diagenetic minerals were characterized by scanning electron microscopy of rock chips, backscattered electron images of thin sections, and electron microprobe analysis.
The conventional core from the upper Missisauga Formation consists of medium-coarse grained sandstone beds deposited as river-mouth turbidites. These beds are cut by liquefied sandstone sills. Sandstones in the conventional core are largely silica cemented, but in places silica overgrowths were
inhibited by the presence of chlorite rims. Kaolinite was an earlier pore-filling cement. Halite is interpreted as a later diagenetic cement. Lithological characterization of the cuttings samples shows substantial down-hole contamination. The "heavy mineral" fraction is dominated by carbonate
cemented chips and few diagnostic detrital minerals or lithic clasts were found. The cuttings samples contain sideritecemented mudstone and siderite or calcite - Fe-calcite cemented muddy sandstone, both probably formed during sea-floor diagenesis. As in the Sable sub-basin, siderite with high Ca
and Mg is most abundant in the Logan Canyon Formation. Late carbonate cements are rare.
In both cuttings and conventional core, K-feldspar makes up 3 - 5 % of the framework grains. Almandine garnet is sourced principally from (meta)mafic igneous rocks. All analysed tourmaline and most analysed biotite is of metasedimentary provenance. Chromite and chrome spinel indicates an
ophiolitic source and is distinctive in the presence of ferrian chromite and the absence of boninitic chromite. Identifiable lithic clasts are principally of granite and volcanic rocks, the latter perhaps from Cretaceous volcanic rocks in Orpheus graben. The detrital assemblage is similar to that in
the Peskowesk A-99 well, but differs in important respects from wells in the Sable sub-basin, notably the abundance of K-feldspar and different assemblages of garnet and chromite.
Chemical fingerprinting of detrital minerals in the Upper Jurassic - Lower Cretaceous sandstones, Scotian Basin
Authors: Pe-Piper G , Tsikouras B , Piper D J W , Triantaphyllidis S
Published: January 2011

Understanding the provenance of sandstones in the Scotian basin using detrital petrology is a petroleum exploration tool because of the importance of Upper Jurassic - Lower Cretaceous sandstone reservoirs. Furthermore, detrital petrology is an important influence
on diagenesis and thus reservoir quality. The chemistry of 25 types of detrital minerals (excluding quartz) has been determined by electron microprobe using samples from the Upper Jurassic - Lower Cretaceous interval in 26 wells across the full extent of the Scotian basin. Variations in mineral
chemistry that can be related to provenance have been analysed for tourmaline, garnet, spinel/chromite, feldspar, muscovite, biotite, amphibole, clinopyroxene, chlorite, epidote and apatite. These mineral chemical compositions are compared with analyses from rocks in the Appalachians and Grenville
province and where necessary the wider literature. Identification of sources for most of the minerals is tentative, due to insufficient analytical data from potential sources on land. Differences in mineral assemblages are found between the following groups of wells: La Have platform, extreme
western Sable sub-basin, main Sable sub-basin, western Abenaki sub-basin, eastern Abenaki sub-basin and SW Grand Banks. Stratigraphic variation is less prominent than geographic variation and is partly masked by diagenetic loss of minerals at burial depths > 2.7
km.
Surficial geology, Deka Lake, British Columbia
Authors: McCuaig S J
Published: January 2011

The Deka Lake map area (92P/10) lies within the Fraser Plateau of south central British Columbia. It is a region of rolling topography with an average elevation of approximately 1200 m above sea level. Most of the region drains to the west via Bridge Creek which
ultimately turns to the north and east and drains into Canim Lake, Mahood Lake, Clearwater River, and North Thompson River. The region is predominantly underlain by till which consists of a poorly sorted diamicton with clasts of all size. Bedrock outcrops are rare and limited in extent. Till is
overlain in places by glaciofluvial sediments which were deposited in meltwater streams at the end of the last glaciation. Glaciolacustrine sediments, deposited in glacial lakes which formed at the end of the last glaciation, were mapped in the Bridge Creek and Deka Lake valleys as well as in the
tributary valleys of Sheridan and Bridge lakes. Lacustrine sediments are present at the periphery of modern lakes throughout the map area. These were deposited at a time when the lakes occupied a higher level. Modern streams sediments (alluvium) are present in extent large enough to be mapped in
some of the valleys. Colluvial deposits including a few large landslides are mapped on steep slopes throughout the map area. During the last glaciation, probably at glacial maximum, ice was dominantly moving to the south southeast as recorded by flutings, crag-and-tails and drumlins (see for
instance the region north and northwest of Bridge Lake). However, an earlier phase of ice flow to the southwest is recorded from the glacial striations. During deglaciation, the drainage through Bridge Creek was dammed and a glacial lake developed in that valley and its tributaries. Part of the
region drained in a subglacial setting, as indicated by the corridor of glaciofluvial sediment, including eskers, east and northeast of Sheridan Lake.

Published: January 2011

The seismic shothole drillers' log database provides baseline, shallow (10-50 m) lithostratigraphic geoscience information on surficial and bedrock geology, hydrogeology, permafrost geology, and geohazards. The revised version 2 database is a greatly enlarged
compilation of 275 871 individual, augered shothole drillers' log records collected from 1954 to present. Originally published as Open File 5465, and containing 76 000 records, the version 2 database has been bolstered by tremendous Industry support, wherein the archival holdings of 16 companies
have been made available for inclusion. Compiled in a Microsoft Access database, the shothole data span the length and breadth of the Mackenzie corridor, Mackenzie Delta, and adjoining petroleum exploration regions of the Northwest Territories and northern Yukon. Data extends across parts of NTS
areas 85, 95, 96, 97, 106, 107, 116, and 117 (fifty-eight 1:250 000 map areas in total). The database has been designed in a manner that allows it to be easily viewed, sorted, and queried. A simple GIS that geographically displays the location of all individual shothole points is included; each
point can be selected in order to see the full litholog record and accompanying metadata. More advanced, thematic GIS based on different data queries, interpretations and mathematical models, have been, or are in the process of being released as companion publications, including: potential granular
aggregate resource assessments, drift isopach models, till isopach models, till facies reconstructions, bedrock outcrop and subcrop maps, geohazard identification, muskeg thickness, massive ground ice occurrence and thickness, extent and depth of permafrost, and reconstructions of bottomfast ice
extents in the offshore Mackenzie Delta region. Information rendered in these various GIS, stemming from the data provided in this publication, will benefit a wide variety of users (e.g., industry, government, aboriginal groups, communities, land and water boards, regulators, and scientists), and
applications (e.g., resource management, land use planning, environmental assessments, infrastructure development, and seismic exploration).
The setting, age, alteration and mineralization at the MAX molybdenum Mine
Authors: Lawley C , Richards J , Anderson R , Creaser R , Heaman L
Published: January 2011

MAX is a porphyry Mo deposit at the northern end of the Kootenay Arc and located near Trout Lake village in southeastern British Columbia (5609565N, 457374E, NAD 83, Zone 11). Molybdenite is hosted by the Late Cretaceous Trout Lake stock (80.2 ± 1.0 Ma; see
below) in a well developed quartz vein stockwork. Intrusive phases range in composition from granodiorite to tonalite and quartz diorite. They intruded multiply-deformed phyllite, schist, and marble of the Paleozoic Lardeau Group which are regionally and contact metamorphosed. Previous studies
demonstrated that many giant porphyry deposits possess long-lived histories characterized by repeated pulses of magmatism and hydrothermal activity. MAX is a relatively small, but locally high-grade porphyry Mo deposit, which lacks multiple long-lived overprinting hydrothermal events. Consequently,
the detailed relative history of small-scale intrusive (dike emplacement) and hydrothermal events (vein paragenesis) can be clearly established. In this study, we attempted to resolve the absolute timing of these intrusive and hydrothermal events by utilizing multiple geochronometers.
Lithogeochemistry and fluid inclusion results were then interpreted within this temporal framework. This poster is a summary of Lawley (2009). MAX is typical of low grade, arc-related deposits associated with fluorinepoor and calc-alkaline magmas (Carten et al., 1997) typical of most porphyry Mo
deposits in British Columbia Low salinity MAX fluids are also typical of porphyry Mo deposits globally. The results of the U-Pb (80.9 ± 1.6 Ma and 80.2 ± 1.0 Ma) and Re-Os dating (80.5 ± 0.4 Ma, 80.2 ± 0.4 Ma, and 80.1 ± 0.4 Ma; average = 80.3 ± 0.2 Ma) of early and
late dikes and molybdenite all overlap within analytical error, showing that magmatism and Mo mineralization occurred on a time scale shorter than the resolution of these methods. 40Ar/39Ar plateau ages for igneous and hydrothermal biotite, and hydrothermal muscovite from Mo veins range from 80 - 76
Ma, and are consistent with cooling ages or minor 40Ar-loss following a short-lived magmatic - hydrothermal event at ~80 Ma
Surficial geology, Louis Creek (west half), British Columbia
Authors: Bednarski J M
Published: January 2011

The Louis Creek (west half) is a rugged upland lying 1200 to 1800 m above sea level. The eastern half of the map area is underlain by Paleozoic volcanic, metamorphic and sedimentary rocks. The west is dominated by Mesozoic batholiths and Tertiary plateau lavas.
Glacial till blankets most of the area, but till cover is thin on local uplands and bedrock outcrops are prevalent. Drumlins and flutings show that during the last glaciation the dominant ice flow was from the northwest in the western half of the map area. Nevertheless a former ice flow from the
north dominates the eastern half of the area. This is part of the southward flow directed by the North Thompson River valley immediately to the east of the map area. Based on till provenance and mapping in adjacent areas, there was a gradual swing in flow direction as the Cordilleran Ice Sheet
flowed in from the northeast and deflected south west flowing glaciers originating from the Cariboo Mountains east of the map area. Moraines and the orientation of meltwater channels indicate that deglaciation progressed to the northwest across the map area.

Permafrost science at ESS: a workshop on GSC/CCRS scientific opportunities
Authors: Wolfe S A
Published: January 2011

The permafrost region occupies approximately half of Canada's land mass. Knowledge of the distribution of permafrost and its physical properties is critical for understanding terrain stability in Arctic environments and is required information for any sort of
infrastructure development (community, transportation or natural resource sector). This knowledge is becoming increasingly important as climate changes, since the distribution and characteristics of permafrost are highly correlated with climatic conditions.
The Earth Science Sector (ESS) provides Canada with multi-disciplinary permafrost expertise. Researchers at Canada Centre for Remote Sensing (CCRS) apply information and data from a range of satellites to assist in mapping and better understanding permafrost environments as well as conducting
change-detection studies. Researchers at the Geological Survey of Canada (GSC) employ a variety of field-based and thermal monitoring techniques to characterize permafrost and better understand terrain processes that may result under a changing climate. Both groups utilize various numerical
modelling techniques to explain observed phenomena and to predict future conditions.
This workshop on Permafrost Science was convened to highlight the various types of permafrost expertise in ESS. In addition, this workshop identified gaps and possible opportunities for new collaborative permafrost research.
Compilation of Sm-Nd isotope analyses of igneous suites, western Churchill Province

Published: January 2011

A compilation has been made of 523 analyses of Sm-Nd isotope ratios of intrusive and extrusive rocks, and presumed orthogneisses, within the western Churchill Province. The data indicate that the region is dominated by juvenile crust extracted from the upper
mantle at 2.7-2.8 Ga, emplaced over older crustal domains with extraction ages clustering at 2.9-3.1 Ga, 3.3 Ga, and possibly 3.5-3.6 Ga. Despite extensive Proterozoic igneous activity within the region, there is very little evidence for emplacement of juvenile magmas younger than 2.6
Ga.
Detailed outcrop measured sections of the Colorado Group in the Foothills of the Calgary region, Alberta, with
reference to shale gas potential
Authors: Hamblin A P
Published: January 2011

In recent years, mudstones of the Colorado Group (and equivalents) have garnered attention as potential reservoirs for shale gas resources. However, the detailed stratigraphy, sedimentology and fracture patterns of most of this clastic wedge are currently not
well known, and further geological research would enhance the outlook for potential resource identification and characterization. This report includes measured sections from three outcrops near Calgary and descriptions of the facies present. These facies, and their potential significance, include 1)
dark grey laminated mudstone (the most likely potential shale gas reservoir), 2) grey bioturbated mudstone (possible shale gas reservoir), 3) thin siltstone to very fine grained sandstone (potential permeable carrier beds), and 4) ironstone horizons (possible permeability
barriers).
Paskapoo groundwater study part VIII: Detailed core measured sections of the Paskapoo Formation in two cores at Sylvan Lake, Alberta
Authors: Hamblin A P
Published: January 2011

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 final subsurface core work in central Alberta, from two wells located at Sylvan Lake, which display strata from the upper portion of the Paskapoo. These latest two cores
were cut during a recent joint project between Geological Survey of Canada and University of Calgary. In this report, the information is presented as standard measured sections, with text descriptions of units. The upper Paskapoo is characterized by thick, multi-storied fluvial channel sandstones
and thinly interbedded siltstones and sandstones. This report is the final installment of basic stratigraphic/sedimentologic information on the Paskapoo, complementary to other Open Files (GSC OF 5392, 5445, 5535, 5536, 5537).
Detailed outcrop and core measured sections of the Kettle Point formation, southwestern Ontario, with reference to shale gas potential
Authors: Hamblin A P
Published: January 2011

The Upper Devonian Kettle Point Formation of southwestern Ontario is an organic-rich, thermally immature, black shale with potential for shale gas resources. The objective of this report is to review the relevant literature, present several outcrop and core
measured sections of this unit, describe the facies present, and speculate on the shale gas potential. Facies, observed in four small outcrops and four cores, include 1) predominant black, laminated, organic-rich mudstone, 2) greenish-grey silty mudstone with sharp bases and ripples, and several
minor facies. The geology and successful shale gas production of the correlative Antrim Shale of adjacent Michigan state is reviewed and compared to the geology of the Kettle Point. Both the Kettle Point, and the coeval, gas-productive Antrim shale of adjacent Michigan, are characterized by a) thick
units of organic-rich mudstone with thin coarser carrier beds deposited in an anoxic, low-energy, distal marine setting, b) high TOC (up to 15% for the Kettle Point and 37% for the Antrim) resulting in a high content of biogenic methane derived from thermally immature Type II/III organic
matter, c) well-developed orthogonal fracture sets, d) shallow drilling depths and consequent low drilling costs. With further study and drilling, the Kettle Point strata of southwestern Ontario may yield economically-significant shale gas resources.
Climate change geoscience program year end report 2009-2010
Authors: Rencz A N
Published: January 2011

The Climate Change Geoscience Program (CCG) at the Earth Science Sector (ESS) contributes to adapting to environmental impacts from climate change through the provision of critical earth science information to support policy and regulation decisions. The
interaction between the development of a scientific knowledge base and the development of appropriate policy decisions is fundamental to achieving meaningful outcomes.
The program's fundamental role lies in providing a suitable base of geoscience knowledge, accomplished by identifying the knowledge needs and gaps through collaboration with stakeholders. Specifically the geoscience in the CCG Program focuses on those environmental variables that will be most
impacted and altered by a changing climate namely the cryosphere (permafrost, glaciers and snow cover), water (availability trends and impacts as well as water level changes) and vulnerable landscapes (particularly coastal areas and northern ecosystems). Significant changes to these components of
the environment will affect Canadians, their prosperity and ability to benefit from their environment.
Scientific activities will quantify the environmental impacts using leading edge techniques that provide excellent knowledge and predictive insights. The scientific knowledge base is being delivered through a mix of earth observation, both remote and in-situ, and quantitative assessments of
landscape and ecosystem response. Projects are multi-disciplinary respecting the multi-dimensionality of environmental issues and the need to study the interaction between variables.
Northern vulnerability is particularly highlighted in the program as evidence for more rapid climate change and accelerating impacts in northern Canada has been cited as a critical driver in the government's Northern Strategy which also recognizes environmental degradation, vulnerable
infrastructure, and transportation as areas requiring attention. The outcome will be achieved through engagement in the current round of national and international assessments, in particular through the Intergovernmental Panel on Climate Change (IPCC) as well as the International Polar Year
(IPY).
Using the open Web as an information resource and scholarly Web search engines as retrieval tools for academic and research purposes
Authors: Naude Filistea , Rensleigh Chris , Du Toit Adeline S.A.
Published: January 2011

This study provided insight into the significance of the open Web as an information resource and Web search engines as research tools amongst academics. The academic staff establishment of the University of South Africa (Unisa) was invited to participate in a questionnaire survey and included 1188 staff members from five colleges. This study culminated in a PhD dissertation in 2008. One hundred and eighty seven respondents participated in the survey which gave a response rate of 15.7%. The results of this study show that academics have indeed accepted the open Web as a useful information resource and Web search engines as retrieval tools when seeking information for academic and research work. The majority of respondents used the open Web and Web search engines on a daily or weekly basis to source academic and research information. The main obstacles presented by using the open Web and Web search engines included lack of time to search and browse the Web, information overload, poor network speed and the slow downloading speed of webpages.
An evaluation of the functionality and delivery of websites of political parties in South Africa
Authors: Crossland Maria , Chigona Wallace
Published: January 2011

The political communication environment worldwide has been transformed by the Internet with websites providing opportunities for affordable information dissemination and reception. Internationally, a party contesting an election without a website seems impossible today. This exploratory study examines the use of websites by political parties during the 2009 South African elections and investigates the functionality offered by the websites as well as how effectively this functionality is delivered. The study analysed the websites of both large and small political parties. It is worth noting that in spite of the lower Internet penetration rates in South Africa, the majority of political parties contesting the 2009 elections had websites. The study shows that the websites of the larger parties generally offer more functionality than those of the smaller parties, supporting the view of ‘normalisation’ of party competition in cyberspace. However, an analysis of the delivery of the content does not confirm the normalisation effects.
Agribusiness Skills Required by Agriculture Students as Perceived by Nebraska -Vocational Agriculture Instructors and Agribusiness Managers

Dr. Tracy Kitchel presented the 2020 AAAE Distinguished Lecture as an online presentation that included break-out room discussions during the Annual Meeting of the American Association for Agricultural Education (AAAE) hosted virtually in May 2021. The 2020 Annual Meeting of AAAE moved to a virtual format and was modified shortly after the COVID-19 pandemic in March 2020; one modification included moving the 2020 Distinguished Lecture to the 2021 Annual Meeting of AAAE. The article is a philosophical work based upon the author’s experiences in the profession and as a higher education administrator.
Farmers' Preferences for Methods of Receiving Information on New or Innovative Farming Practices
Authors: Riesenberg Lou E. , Gor Christopher Obel
Published: January 2011

The mission of Land Grant Institutions (LGIs) and Cooperative Extension has always included the concepts of educational access and inclusion, but not all communities have equitable access to Extension programs. Specifically, Extension is currently only serving about 10% of Indigenous communities. Given the complicated history of Indigenous land dispossession that created LGIs, it is imperative that Indigenous communities have equitable access to the benefits of Extension’s educational and agricultural programs. Despite these challenges, there are 1862 Extension educators that collaborate with Indigenous communities. Through a transformative convergent mixed methods study, I investigated the Western Region of Extension to learn about the characteristics that help to make Extension programs in Indigenous communities successful. The interviews and survey responses revealed these characteristics, including centering the community’s goals, having an Insider Collaborator, and creating culturally relevant programming and pedagogy. From the findings of this study, my participants and I co-constructed implications and recommendations to help make these programs successful and provide equitable support to Indigenous communities.

AG*SAT: An International Distance Education Alternative
Authors: Bowen Blannie E. , Thomson Joan S.
Published: January 2011

Numerous changes occurring within the profession of agricultural education are prompting agricultural educators to explore the advantages of delivering credit instruction via distance education technologies. In this regard, the Agricultural Satellite Corporation (AG*SAT), a consortium of primarily land grant universities, commissioned a study to assess the opportunities for institutions to deliver more agricultural and natural resources instruction via the AG*SAT network. The findings of this assessment indicate that these institutions want to deliver more instruction via satellite. This instruction focuses primarily upon emerging topics and areas in which the universities have limited capacity to fulfill. The findings provide numerous implications and opportunities for agricultural educators.
