Selwyn basin geophysics for parts of 105I, 105J, 105K, 105N, 105O, and 105P
In 2008 Exploration Syndicate Inc. contracted Geotech Inc. to fly a regional-scale ZTEM survey covering a 25,000 km2 area (1 km line spacing) in the Selwyn basin. The survey footprint straddles the Canol Road in east-central Yukon and overlaps into the western Northwest Territories. In March 2013 Yukon Geological Survey purchased the survey data, and in May we received approval to distribute the data publicly. As no interpretation was included with the purchase of the data, Condor Consulting Inc. offered to process the data and generate maps, gridded data, and a report. Condor undertook the work at no charge, and their contribution to the project is gratefully acknowledged. This Miscellaneous Report comprises a number of parts: - original survey report produced by Geotech Ltd. describing the data acquisition and processing parameters; - raw survey data acquired from Exploration Syndicate Inc.; - a report summarizing the processing and interpretation undertaken by Condor Consulting; - a series of maps in pdf and tiff formats; and - gridded data. File sizes are large. If you experience problems downloading any of the products or would like to obtain the raw data, Geotech data, Multiplots, or any of the other files please contact us at geology@gov.yk.ca. The project was funded by the Canadian Northern Economic Development Agency (CanNor) through their Strategic Investments in Northern Economic Development program.

Bedrock geology of Lansing Range map area (NTS 105N), central Yukon
공공데이터포털
Mainly schitose clastic strata of the northern Selwyn basin underlie Lansing map area. These strata form rounded mountains, although jagged ridgelines occur in the thermal metamorphic aureoles surrounding six Cretaceous granitic plutons. Major faults occupy some broad northwest-trending valleys: two of these extend eastward as the Hess and Macmillan faults (Abbott and Turner, 1990) in the Macmillan Pass area; another appears to contine westward as the Robert Service Thrust Fault. Argentiferous galena veins were intermittently mined from the east edge of the map area from 1976 to 1985; whereas the stratiform base metal and disseminated gold potential of these rocks have been investigated during the 1990s.

Geophysical Series, NTS 115K/1, Airborne Geophysical Survey Southern Stevenson Ridge area, Yukon
공공데이터포털
A quantitative gamma-ray spectrometric and aeromagnetic helicopter-borne geophysical survey was completed by Fugro Airborne Surveys. The survey was flown from September 10 to October 14, 2008. The nominal traverse and control line spacings were 400m and 2400m respectively, and the aircraft flew at a nominal terrain clearance of 125m. Traverse lines were oriented at 0 degrees with orthogonal control lines.

Geology of the Jakes Corner Geophysical Survey Area, Southern Yukon (105C/12, 105D/8 and 9)
공공데이터포털
Interpretive geology of the Jakes Corner geophysical survey, southern Yukon, (NTS 105C/5 and 105D/8,9) including one 1:50,000-scale map and an interpretive report. The accompanying geological map is designed to be overlain upon the 1:50,000 geophysical maps of Open File 1994-10(G). It incorporates published geological information which has been modified to accord with constraints provided by the geophysical data as well as from publicly available assessment reports and limited field checking. The map is highly interpretive, except for the eastern portions which benefit from mapping by Gordey and Stevens (1994b). Elsewhere, mapping concentrated on defining blocks with a uniform geophysical expression which could represent a particular rock unit. Sharp magnetic gradients between units are considered to represent faults, or where applicable, intrusive contacts. Structural relations between units are generally interpretive and may not be consistent throughout the map area. This report describes the rock units that occur in the survey area and elaborates on the mineral deposit types that might occur there.
Soil reconnaissance of the Fort Selkirk volcanic field, Yukon (115I/13 and 14)
공공데이터포털
Valley-filling basalts of the Selkirk Volcanics north and west of the Pelly River-Yukon River confluence, range in age from early Pleistocene to Holocene. Soils formed on the older surfaces have complex parent materials reflecting early Pleistocene glaciation and significant loess accumulation. A diamicton overlying the early Pleistocene basalt is covered by up to 1 m or more of calcareous loess, and shows no field evidence of weathering or soil formation. Middle Pleistocene basalt has a similar depth of loess cover and appears fresh and unweathered. Lava flows originating on the south side of the Volcano Mountain cinder cone display vegetation ranging from discontinuous lichen and moss cover to white spruce-aspen forest. Soil profile development varies correspondingly from almost nil to reddish-brown Brunisolic soils with ~30 cm of B horizon, depending on substrate age and/or the presence of lapilli deposits overlying the flows.

Data were acquired during an airborne geophysical survey (gamma ray spectrometer, magnetometer and VLF-EM) carried out by Fugro. Funding was provided by the Government of Yukon. The survey was completed between July 29 and September 21, 2000.
