Residual magnetic field: This image shows the colour-coded map of the residual magnetic field. The image has a pixel size of 42m. The area north of 65N consists of digitized data resulting from two surveys flown between 1966 and 1974. A flight-line spacing of 800
m and flight altitude of 305 m above ground were used in both cases. South of 65N, data were acquired digitally in three surveys flown between 1996 and 1997. A flight-line spacing of 800 m and flight altitude of 150 m above ground were used for these surveys. The International Geomagnetic Reference
Field for the date and altitude of each survey has been removed.
Vertical gradient of residual magnetic field: This image shows the colour-coded map of the vertical gradient of the residual magnetic field. The image has a pixel size of 42m. The area north of 65N consists of digitized data resulting from two surveys flown between 1966 and 1974. A flight-line

vertical gradient of the residual magnetic field emphasizes the magnetic effects of near surface magnetic sources and suppresses the effects more deep-seated sources. Therefore, it is an effective way of highlighting those anomalies related to surface geological variations (lithological and
structural). Compared to the residual magnetic field image, the vertical gradient image is more detailed - it contains more short-wavelength information.
Bouguer gravity anomalies: This image shows the colour-coded map of the Bouguer gravity anomalies. The gravity data used to compile this map have a spacing of 10 km, on average. All measurements were reduced to the IGSN71 datum and theoretical gravity values were calculated from the Geodetic
Reference System 1967 (GRS67) gravity formula. Bouguer anomalies were calculated using a vertical gravity gradient of 0.3086 mGal·m-1 and a crustal density of 2 670 kg·m-3. Areas on land are represented by Bouguer anomalies and areas offshore, by free-air anomalies. For this map, the data
were gridded to a 2 km interval. The image grid has a 127-metre interval.

New insights into the geological history of the basement rocks to the southwestern Athabasca Basin, Saskatchewan and Alberta
Authors: Card C D , Panã D , Stern R A , Rayner N
Published: March 2017

Much of the basement to the southwest Athabasca Basin comprises rocks of the Lloyd Domain. These include the Careen Lake Group, a melange of metasedimentary rocks, parts of which are correlative with Archean Murmac Bay Group and Rutledge River Basin rocks. These
rocks were intruded by ca. 1985 - 1968 Ma plutons of the Taltson magmatic zone. The Lloyd Domain was divided by weakly
deformed 1843 Ma granite and 2500 Ma granitic gneiss of the Clearwater Domain. To the east, supracrustal rocks of the 'Virgin schist group' are at the boundary between the Virgin River and Lloyd domains.

Most basement rocks to the western Athabasca Basin were subjected to multiple deformational and metamorphic events. The Virgin River shear zone was subjected to multiple displacement episodes under ductile, brittle-ductile, and brittle conditions. Brittle reactivation of the Virgin River shear zone,
along the Dufferin Lake Fault, played a role in concentrating uranium at the basal unconformity of the Athabasca Basin.
Topographic influences on the sedimentology of the Read and Manitou Falls formations, eastern Athabasca Basin, Saskatchewan
Authors: Long D G F
Published: March 2017

In the eastern Athabasca Basin, Read and Manitou Falls formations unconformably overlie high-grade Wollaston and Mudjatik gneiss domains. Stratal architecture and paleocurrents of basal strata at the SueCpit at McClean Lake and the Deilmann pit at Key Lake
indicate that initial deposition was strongly influenced by basement paleotopography, with early deposits confined between distinct valley walls.
Stratigraphically younger units experienced less direct basement influence on river patterns. They are likely to have formed by deposition on amalgamated braidplains, essentially at or near grade, filling a broad, nearly flat accommodation space. Drill logs at McArthur River and Cigar Lake suggest
that paleotopography there also influenced the basal lithofacies, as cobble and large pebble conglomerate accumulated in rivers that ran parallel to basin-margin faults. Some uranium ore bodies occupy low-relief, mature topographic depressions along pre-existing fault trends; others overlie basement
ridges. Systematic paleocurrent measurements in inclined exploratory cores may aid selection of exploration targets, especially where paleocurrents deviate from regional trends.
Stratigraphy and sedimentology of the Maybelle River area, western Athabasca Basin, Alberta
Authors: Post R T , Kupsch B G
Published: March 2017

Three unconformity-bounded formations of the Athabasca Group were examined in the Maybelle River - Net Lake area. The lowermost, Fair Point Formation (FP) is here subdivided into lower (FP1) and upper (FPu) conformable members. Fair Point Formation lower member
comprises local, massive to planar-bedded siltstone beds interpreted as shallow lake deposits in fault-controlled paleovalleys, interbedded and overlain by matrix- and clast-supported pebble conglomerate and pebbly sandstone deposited by high-velocity streams forming a prograding alluvial plain.
Fair Point Formation upper member (FPu) is massive to crossbedded, coarse-grained sandstone, also interpreted as a prograding alluvial plain. Manitou Falls Formation (MF) comprises a lower, crossbedded, medium- to coarse-grained sandstone (unit MFc) and an upper, ripple-crosslaminated,
medium-grained sandstone (unit MFd). These are
equated to proximal units in Saskatchewan and record relatively low-velocity, distal, braided-river-system tracts. The uppermost, incompletely preserved Lazenby Lake Formation is massive, ripple-laminated, convolute-bedded, pebbly sandstone with sedimentary characteristics as in the Manitou Falls
Formation, and records deposition by low-velocity, braided streams.
Environmental significance of oncoids and crypto-microbial laminates from the Late Paleoproterozoic Athabasca Group, Saskatchewan and Alberta
Authors: Yeo G M , Percival J B , Jefferson C
W , Ickert R , Hunt P
Published: March 2017

Centimetre-sized, concentrically laminated structures from lower Athabasca Group strata at Maybelle River and Hook Lake in southwestern Athabasca Basin are interpreted to be organosedimentary clay oncoids that grew in pools in ephemeral river systems or in
scattered lakes that developed during an erosional hiatus after deposition of the Fair Point Formation. In the Read Lake area, microscopic laminae are preserved in microcrystalline quartz that cements angular siliciclastic breccia fragments; these are also of probable microbial origin. These
observations contribute to a growing body of evidence for life in Proterozoic nonmarine environments. They also suggest a humid regional climate postdating Fair Point Formation deposition and predating deposition of the Read and Smart formations, that have characteristics of flashy braided river
deposits laid down in an arid environment. Furthermore, these rare organosedimentary features have the potential to be a unique stratigraphic marker in Athabasca Basin.
Depositional age of the Douglas Formation, northern Saskatchewan, determined by Re-Os geochronology
Authors: Creaser R A , Stasiuk L D
Published: March 2017

Rhenium-osmium geochronology of organic-rich shale of the Douglas Formation, northern Saskatchewan, yields a precise date of 1541 ± 13 Ma (2? uncertainty, Model 1 isochron), which is interpreted to be the depositional age of the samples. This result provides
a robust determination for deposition of some of the youngest sedimentary rocks within the Athabasca Basin, and extends the confirmed duration
of sedimentation by about 100 million years. The Re-Os date for the Douglas Formation (sequence 4) suggests that a substantive hiatus is recorded at the unconformity between rocks of sequence 3 and sequence 4. The Re-Os age is also similar to the oldest published ages of uranium mineralization
within the deeper basin, suggesting that the onset of mineralization was broadly contemporaneous with deposition of the youngest sediments in the Athabasca Basin.
Alteration features and geochemical signatures of the Maybelle River uranium zone, Athabasca Basin, Alberta
Authors: Kupsch B G , Catuneanu O
Published: March 2017

The Maybelle River uranium zone comprises several drill intersections up to 20.9% U3O8 over 5 m, in basal Fair Point Formation just above the unconformity with a paleoweathered graphitic mylonitic zone in gneissic basement. Detailed petrography of selected
drill-core samples documents an alteration halo with the following similarities to those surrounding polymetallic uranium deposits in the eastern Athabasca Basin of Saskatchewan: massive clay replacement, quartz dissolution and sandstone collapse, drusy quartz- and pyrite-lined fractures, chlorite
overprinting, and bleaching. Regional interstitial illite and dickite are replaced by chlorite and additional illite in strata surrounding the uraniferous zone. Lithogeochemistry of drill core reveals a polymetallic ore assemblage: uranium, arsenic, nickel, boron, phosphorus, molybdenum, and cobalt.
These studies confirm the geological environment of the western part of Athabasca Basin as favourable for major unconformity-related deposits as in eastern and central parts of the basin, and provide guides to further exploration.
Comparison of lower Athabasca Group stratigraphy among depositional systems, Saskatchewan and Alberta
Authors: Yeo G M , Jefferson C W , Ramaekers P
Published: March 2017

The ca. 1.74 - 1.64 Ga lower Athabasca Group comprises four regional formations distributed among five fluvial depositional systems that prograded into the Athabasca Basin from different directions. Understanding these deposystems should aid exploration for the
world's richest uranium deposits located at the basal unconformity with gneissic basement. Fair Point Formation conglomerate and coarse-grained lithic sandstone were transported westerly via the oldest, Fidler deposystem, preserved only in western Athabasca Basin. The Robert deposystem introduced
Smart Formation sandstone from the southwest, onlapping the Fidler deposystem. A contemporary eastern phase of the Ahenakew deposystem introduced the Read Formation conglomerate, pebbly mudstone, and sandstone from the south and east. Finally, the broadly coeval Ahenakew, Karras, and Moosonees
deposystems deposited the Manitou Falls Formation
from the east, southeast, and northeast, respectively. The five Manitou Falls Formation members become thinner, finer, and indistinct toward the west where they overlap the Robert and Fidler deposystems.
Spring geochemistry: a tool for mineral exploration in the south Nahanni River Basin of the Mackenzie Mountains, Northwest Territories
Authors: Caron M -E , Grasby S E , Ryan M
C
Published: March 2017

Geochemical data from 155 spring locations within the remote 37,000 km2 South Nahanni River basin of the Mackenzie Mountains, Northwest Territories, were used to evaluate the economic mineral potential of the region, an area proposed for a national park
designation. Trace element analyses were evaluated using three different approaches (the sum of trace element concentrations as a percentage of total dissolved solids, identifying individual anomalously high trace elements, and the inverse use of the Ficklin Diagram). Two out of the three approaches
detected the two known deposits of the area, Prairie Creek and Tungsten, but not with the same method in each case, indicating that a multi-pronged approach is best. The springs were determined to be elevated in trace elements in comparison to waters related to mining deposits around the world.
Silica geothermometry determined the average depth of circulation of the springs to be 2.1 km for warm or hot springs, and ranging from 4.7 km to less than 200 m for the entire dataset, which is indicative of the
accessibility of the predicted mineralized zones. These simple statistical and graphing methods can successfully identify mineralized zones quickly and efficiently in a largely under-explored area.
A review of the Late Cretaceous Little Nahanni Pegmatite Group and associated rare element mineralization in the Selwyn Basin area, Northwest Territories
Authors: Barnes E M , Groat L A , Falck H
Published: March 2017

The Late Cretaceous Little Nahanni Pegmatite Group (LNPG) is composed of more than 200 subvertical, lithium-cesium-tantalum (LCT) pegmatites, occurring in an area of approximately 55 km2. The pegmatite group is hosted by Selwyn Basin offshelf facies of the
Neoproterozoic to Lower Cambrian Hyland Group and is located between, and subparallel to, major regional northwest-trending structures, such as the March Fault and the Fork Anticline.

Since their discovery in 1961, these coarse-grained, mostly quartz, feldspar, and spodumene pegmatites have been investigated for economic concentrations of rare elements. Whole-rock geochemical analyses indicate granitic compositions and strong peraluminous signatures suggest an S-type affiliation.
The depletion in rare earth element (REE) abundance, enrichment of Li, Ta, Cs, Sn, Rb, and Nb, and emplacement into low-pressure metamorphic rocks is typical of LCT pegmatites.

There are similarities between the LNPG dykes and the Greenbushes pegmatite, Australia, which is rich in Sn, Ta, Nb, and Li (Wengzynowski, 2002). However, even closer geochemical comparisons can be made with examples of European late-Variscan, post-orogenic mineralized plutons and pegmatites. One
such example, the Beauvoir granite, is suggested as an analog for the plutonic source of the LNPG dykes. Comparison of the setting and ages obtained for the emplacement of the LNPG with this well studied Variscan granite suggests a period of post-orogenic collapse and extension during the late
Cretaceous period in this region of the northern Cordillera.
Modelling mineral potential for the Greater Nahanni Ecosystem using GIS-based analytical methods
Authors: Harris J R , Lemkow D , Wright D F , Falck H
Published: March 2017

Mineral potential within the Greater Nahanni Ecosystem was modelled in a Geographic Information System (GIS) for four different deposit models: 1) SEDEX -stratiform shale-hosted sedimentary-exhalative Zn-Pb-Ag, 2) 'carbonate-fault' - carbonate-hosted
zinc-lead-silver associated with major faults, 3) 'intrusion-related' - includes skarn, rare metals and gemstones), and 4) Carlin-type gold as lode and/or derived placer deposits. This mineral-potential modelling study integrates data collected during two Mineral and Energy Resource Assessment
(MERA) projects. The results have contributed to the process of determining the geographic boundaries of the proposed expansion of the Nahanni National Park Reserve.

Four mineral potential maps were produced (one for each model) using a data-modified knowledgedriven approach. A weighting scheme, based on integrated mineral deposit and regional geological knowledge, was derived for the various evidence maps for each deposit model. The four potential maps, plus a
fifth map of hydrocarbon potential based on the Nahanni MERA 1 assessment, were then combined into a final mineral-potential map using two algorithms: an additive operator and a maximum operator. Prediction plots of the four deposit models show that partial data sets provide reasonable predictions
of the remaining known data.

Several areas within the study area were identified as having very high mineral potential. For SEDEX zinc-lead-silver type deposits, five areas were identified: A) Howards Pass at the northwest end of the 'zinc corridor'; B) another strand of this corridor northwest of the Cantung mine; C) the
Meilleur River Embayment; D) Selena Creek; and E) east of Prairie Creek. For carbonate-fault zinc-lead-silver deposits, five areas are highlighted: F) Prairie Creek; G) Broken Skull Fault; H) Selena Creek; I) Howards Pass; and J) southeast of the Cantung mine. For intrusion-related deposits, three
areas stand out: K) Selena Creek; L, M, N) a broad zone intruded by the Tay River plutonic suite including Cantung; and O) O'Grady Batholith. Finally, for the Carlin-type lode and/or placer gold deposits, six areas have high ratings: P) Selena Creek; Q, R, S) a broad linear zone of intrusions
dividing and overlapping the 'zinc corridor'; T) surrounding the Mount Hamilton pluton; and U) in and around the O'Grady batholith. High natural gas potential was assessed under the MERA 1 project in the southeast corner of the study area, over the untested Etanda Dome and Twisted Mountain
Anticline, as well as over the partially explored Mattson Anticline.

Magnetotelluric monitoring of impedance in an area of induced seismicity at Manic 3, Quebec
Authors: Kurtz R D , Niblett E R
Published: March 2017

Seismic activity associated with the filling of the Manic 3 reservoir north of Baie Comeau, Quebec commenced in September 1975. Afler the magnilude 4.1 earthquake of October 23, 1975 three magnetotelluric (MT) stations were established in the area to monitor the
electrical impedance of the earth and to relate any changes with the seismic activity. Two of the stations operated for over 1.5 years. During this time it was found that if any time dependence existed, it had the nature of a linear increase in the impedance of about 113 per year. There were no
significant variations observed in the angle of polarization of the telluric fields nor were there any significant changes in the geomagnetic transfer functions. Afler the stations were installed, the seismic activity slowly decreased to very low levels. No large earthquake was predicted by the
magnetolelluric results and none occurred.
The apparent resistivity curves along the major axis of anisotropy from the three stations are nearly the same as are the minor resistivity curves from two of the stations. They are similar to other MT curves obtained in the Grenville. The major axis of anisotropy is approximately north-south at all
three stations. In addition, the transfer functions are nearly identical. The MT data are consistent with a substantial conducting layer at the base of the crust.
Case study 8. Geological mapping derived from topography
Authors: Morris W A , Ugalde H , Slavinski H , Markham K
Published: March 2017

A geological boundary is outlined by topography when the two lithologies meeting at the contact have contrasting physico-chemical characteristics. The topographic response of the contact is related to the differential response of the various rock types to local
weathering activities. Local climatic conditions may either accentuate or retard the erosion of rock types.
Derivation of topographic information comes from three types of surveys: distance ranging, stereogrammetry, and interferometry. For each of the three types of surveys, there are variations in the methods with which data are acquired. One of the most critical issues concerns the acquisition format.
If isolated elevation points are acquired, then computation of a representative Digital Elevation Model (DEM) necessitates a gridding algorithm and care must be exercised to understand the impact of the gridding. In contrast, when a swath of elevation points is acquired, the quality of the DEM is
defined by the pixel resolution of the acquisition instrument.
Examples of the use of topographic mapping of geology are given for a) flat-lying strata (Cypress Hills, Alberta); b) regional-scale folded strata (Whitefish Falls, Ontario), and c) highly deformed gneiss terrain (Grenville Province, Key Harbour, Ontario).
Eurekan fault tectonics on Judge Daly Promontory and their implications for displacements along Nares Strait
Authors: von Gosen W , Piepjohn K , Tessensohn F , Saalmann K
Published: March 2017

On Judge Daly Promontory, faults cut through a lower Paleozoic sedimentary succession and also affect small Paleocene occurrences. Structural analyses suggest that displacements were caused by a sinistral transpressive regime under north-northwest -
south-southeast to northwest - southeast compression, which led to the formation of major faults and fault zones displaying sinistral, oblique, or reverse displacements. The deformational history is interpreted to have taken place in two stages: sinistral pull-apart graben formation during the
Paleocene, followed by compression in the Eocene, and involved reactivation of former sinistral strike-slip faults. In a plate-tectonic scenario these two stages of deformation suggest that displacements along the Wegener Fault were related to 1) the sinistral displacement of the North American
plate with respect to Greenland, and 2) the northward drift of Greenland as a result of combined seafloor spreading in the North Atlantic and Labrador Sea. The amount of left-lateral movement along the Wegener Fault does not support the existence of a plate boundary in Nares
Strait.
Physical properties of clay-rich sediments: a database of Deep Sea Drilling Project results
Authors: Nobes D C

A database of physical properties for clay-rich sediments has been constructed using Deep Sea Drilling Project results as tabulated in the DSDP Initial Reports, Volumes 1 through 86. The physical properties database has been set up at the Pacifie Geoscience
Centre. The database consists of 4299 records. Each record contains a sample identification code, the depth, and whatever values of density, porosity, water content, void ratio (computed from porosity), thermal conductivity, compressional wave velocity, and shear wave velocity as may be available
for the sample. In addition, the clay, sand, and carbonate content, expressed in volume percent, the major clay mineralogy and the tectonic setting are included if available. The database may be used for studies of clay physical properties and their interrelationships. An example is presented for
the variation of water content, density, thermal conductivity, and compressional wave velocity versus porosity.

Feasibility study in the use of geothermal energy to heat large facilities
Authors:   UMA Engineering Ltd.
Published: March 2017

This study evaluates the technical and economic potential of using low temperature geothermal energy ta heat large buildings in Edson, Alberta. Geological studies have indicated the presence of low temperature geothermal energy. Saline water lying in aquifer
formations at depths of 1.5 ta 3.5 kilometres has temperature of 49°C ta 95°C respectively. A large area in the northern part of Edson was identified containing some large buildings including a hospital and 6 schools. The area is capable of accommodating at least three more large
buildings. The municipality owns land suitable for pipeline corridors ta connect these facilities ta a geothermal energy hot water distribution system. None of the geothermal systems examinéd are found ta be cost effective in terms of pay-back of capital costs by displacement of natural gas
energy use. A small scale research oriented project using low cost abandoned gas wells appears ta be a logical first step in developing a full scale prototype system.

The seismic traveltime drop in the Charlevoix region from 1979 to 1980: evidence for aligned, saturated cracks in the crust

belief that this traveltime drop was caused by the closing of wate r saturated, aligned cracks in the crustal material underneath the St. Lawrence River. This would requit-e a decrease in pot·e volume of the rock~ and so lead to subsidence in this area. However, repeatcd levellings

MOSES method is then developed and followed by numerical modelling of its response ta one and three dimensional typical arctic structures. The report concludes with the detailed proposal and budget for an Arctic experiment.
1984 geothermal investigation Prince Edward Island drilling, MacDougall, Prince County hole number EPB 345
Authors:   John A. Leslie and Associates Limited
Published: March 2017

A hole was drilled to a depth of 460 m near MacDougall, Prince Edward Island, to obtain a measurement of temperature gradient as part of an assessment of the geothermal energy potential of the region. A single temperature measurement from the bottom of a 3000 m
hydrocarbon exploration well nearby indicated a gradient of 27 mK/m (27 degrees per kilometre). The accurate temperature measurements in the shallow well showed that the gradient is in fact only 14 mK/m. There is therefore no potential for low-grade geothermal heat utilisation in the area. The
report contains details of the drilling operation, a complete lithologie log, and the initial series of temperature logs.
Expérimentation sur le gel d'un sol et d'une canalisation enterrées et refroidie dans une installation d'essai de grandes dimensions, 3e phase
Authors:   Geotechnical Science Labortatories
Published: March 2017

In 1982 a Canada-France research project to study soil freezing around a buried refrigerated pipeline began in the controlled environment test facility of the Centre de Géomorphologie in Caen, France. This report presents the results of the short thaw cycle
which followed the first freezing period (pipe at -2°C) and of the second freezing cycle (pipe at -5°C) which began in 0ctober 1983. Keasurements of the thermal and hydraulic regimes, of total soil pressure and of pipe deformation are included. A heave of 16 cm in the silt and a pipe
stress of 160 MPa were observed 250 days into the second freeze cycle. The results of soil frost heave tests performed in Carleton University laboratories and a discussion of the various methods for predicting heave are also presented, with an emphasis placed on the influence of test and sample
conditions.
