Principal Investigator: Corcoran, Patricia
Licensed Year(s): 1997
Summary: Research involves mapping and sampling of rocks for geological study. Equipment and all crew members will be transported to and removed from base camps by float plane (twin or turbine otter). A zodiac with 10-20 hsp motors will be used to travel within the study area. Rock samples (5-15 lbs) will be collected, small and large-scale maps will be compiled. The study will provide information about...

Principal Investigator: Clowes, Ron M.
Licensed Year(s): 1997
Summary: This refraction seismic project is part of larger transect which extends from Yellowknife to Stewart on the west coast of BC. Part of the sequence of Earth & Ocean Science studies to provide an in-depth image of the deep structure of the Earth throughout the region and will help to define the sequence of emplacement of various types of rock formations in the region. Pre-experiment: 1) Flag reco...

Principal Investigator: Perks, Matthew
Licensed Year(s): 1996 1995
Summary: Examination of the temporal and genetic relationship between metamorphism and granitoid magmatism will be achieved through detailed mapping of granite-metasediment contacts to examine the thermal effects of granite intrusion. This will rely on a detailed documentation of the mineral assemblages, textures, metamorphic grade, and relative timing of the meta-sedimentary and meta-igneous rocks in the...

Principal Investigator: Stubley, Mike
Licensed Year(s): 1996 1995 1994 1993 1992 1991 1990
Summary: The researchers will examine, document, and sample surface outcrops in the study area. The information will be recorded on a map which will summarize the geological rock-types and mineral resources of the area. The researchers will camp at two separate sites during the field season. The work will consist primarily of daily walks from wherever they can get their inflatable boat. Airplane suppor...

Principal Investigator: Pehrsson, Sally J
Licensed Year(s): 1996 1995 1994
Summary: This will be the final summer of work for this phase of mapping in Indin Lake. The mapping data (including structural, petrological, geochemical &geochronological) will enable a detailed geological history of the project area to be constructed. This will include timing of major events, including volcanism, plutonism and sedimentation, and subsequent deformation. The results will be presented in...

Principal Investigator: Eaton, David
Licensed Year(s): 1999 1996
Summary: Since the region of investigation (down to a depth of 50 km or more) is inaccessible, geophysical techniques will be used. One technique will be seismic reflection profiling, a method adapted from the oil industry. Large vehicles are use to generate seismic waves, which travel downwards and reflect off boundaries. These echoes are recorded by surface instruments, and the data are processed to p...

Principal Investigator: Thompson, Peter H.
Licensed Year(s): 1994 1992
Summary: This is the concluding summer of a regional scale bedrock mapping project, with associated geochronology sampling. The researcher will accomplish this by boat, foot and occasional fixed wing and periodic helicopter support. All the data will be digitally entered for computer map compilation and generation....

Principal Investigator: Kjarsgaard, Bruce
Licensed Year(s): 1994 1992
Summary: This will be the final field season of this bedrock mapping project, which is being done to update geological knowledge in the Lac de Gras area (which was last mapped in the 1940s). Detailed mapping, geochemical and geochronologcical studies will be used to help understand the geological evolution of this area. Mapping will be accomplished by foot and boat traverse with fixed and rotany wing sup...

Principal Investigator: Hrabi, Blair
Licensed Year(s): 1994
Summary: This will be the final summer of field work for this project. The detailed mapping data in combination with geochemistry will enable the researcher to gie a detailed geological history of the area, including timing of certain geological events (age of volcanism and granite plutons) as well as a deformational history....

Principal Investigator: Groat, Lee A.
Licensed Year(s): 1995 1994 1993
Summary: The researchers will continue their study, begun in 1993, on the pegmatites found in the Selwyn Mountains and other western Canadian locations. Pegmatites contain rare elements such as lithium, beryllium, rubidium, niobium, cesium and talalum. This study will result in a summary of information on pegmatites, including detailed information on their classification, origins and economic potential....
