Did the formation of the Great Unconformity trigger oxygenation and the Cambrian explosion?
Principal Investigator: Macdonald, Francis A
Licensed Year(s): 2019
Summary: This proposal aims to constrain the timing, magnitude, and spatial heterogeneity of erosion that lead to development of the Great Unconformity (GU) to test hypotheses for oxygenation and the Cambrian explosion. The GU is one of the most geologically significant and largest temporal gaps in the rock record, marking the boundary between Precambrian and Phanerozoic time. It has been proposed that ero...


Detailed study of the rhyolite dome and surrounding volcanic rocks at Sunset Lake, Slave craton, Northwest Territories
Principal Investigator: DeWolfe, Michelle
Licensed Year(s): 2019
Summary: This research is focused on increasing the understanding of the geological history of the Sunset Lake area through a detailed examination of ancient volcanic rocks exposed in this area. This work will be conducted mostly by hiking on foot. Zodiac boat with 25hp outboard motor or canoe will be used to reach the start of the hike each day. The hikes will be no more than 2 km from the lakeshore. D...


Uplift history of Fort Liard area
Principal Investigator: McMechan, Margot
Licensed Year(s): 2015
Summary: To determine any north south changes in the uplift history of the Fort Liard area. The research team will hike/walk to the outcrop. The team will use a 3 pound sledge hammer and rock hammer to collect hand-sized samples of rock from loose and fallen pieces. The time spent at the outcrop is about 2 hours then the team will return via foot. After, the field work samples will be sent to labs where...


Geological Mapping, Stratigraphic and Structural Analysis in the Aklavik Range and Adjacent Parts of the Northern Richardson Mountains.
Principal Investigator: Lane, Larry S
Licensed Year(s): 2001
Summary: The research team proposes three activities. Geological mapping at a 1:50,000 scale, carried out by the Geological Survey of Canada, will provide an updated and detailed geological map of the Aklavik Range, which was previously mapped at reconnaissance scale in the 1960's and 70's. Stratigraphic studies will consist of detailed measurement and description of specific rock units of Jurassic and Cr...


Collection of Silurian fishes and trilobites and articulated remains of Devonian chondrichthyans and other fishes from the Mackenzie Mountains, N.W.T.
Principal Investigator: Wilson, Mark V.H.
Licensed Year(s): 2013 1998 1996 1990
Summary: The objectives of the research are 1) to collect remains of Silurian and Devonian fishes, and 2) to collect remains of Silurian trilobites. Activities are limited to travel, residence at camp locations and collection of fossils. Helicopters will be used to access camp sites. We plan to land at Avalanche Lake on July 15, spending 6 days collecting fossils at Avalanche Lake, followed by one day of t...


Thematic Structural, Stratigraphic and Geochronological Studies of the Slave Structural Province.
Principal Investigator: Bleeker, Wouter
Licensed Year(s): 2000 1999 1998 1997 1996 1995 1994
Summary: Map and describe the various rock types and assess their role in the complex geological history of the Slave Province. Fly-in / fly-out camps with small float planes to make daily traverses by foot or by boat to study the local rocks and collect small handsamples for laboratory work....


Detailed bedrock mapping in the Indin Lake area
Principal Investigator: Pehrsson, Sally J
Licensed Year(s): 1996 1995 1994
Summary: This will be the researcher's concluding summer for this project. The detailed mapping data (structural, petrological) in combination with the geochemical and geochronological sampling will be accomplished by foot and boat traverses with occasional fixed and rotary wing support. All data will be entered digitally for computer map compilation....


Taxonomic and Biostratigraphic Studies of Silurian (about 400,000,000 years ago) Graptolites (extinct organisms) and Radiolaria (micro-organisms) of Central Arctic Islands.
Principal Investigator: Lenz, Alfred C.
Licensed Year(s): 1994 1993 1992 1991 1990 1989 1988
Summary: The researchers will collect samples of shales and limestone at regular intervals (usually about every 1 metre or less). Samples of rock of up to 1-2 kg are collected from each horizon. Samples will be bagged and shipped back to the university for further study. This study will help researchers better understand the geological history of the Arctic....


The Dubawnt Super Group
Principal Investigator: Peterson, Tony D.
Licensed Year(s): 1994
Summary: Collection of rock samples and subsequent study by examination of thin sections, geochemical analyses, and geological mapping. Work in the field is conducted by boat and foot traversing with some support by aircraft. This will be done in order to determine the geological history of Archean crystalline rocks....


Detailed Bedrock Mapping in the Winter Lake Supracrustal Belt
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....
