Regional bedrock mapping of the Paleoproterozoic Hill Island Lake assemblage and underlying basement rocks
chercheur principal: Canam, Rebecca
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No. 5905. The Hill Island Lake bedrock mapping project is a multidisciplinary geosciences program led by the Northwest Territories Geological Survey, in collaboration with several university researchers. The main research objective of this project is to conduct regional bedrock mapping and supporting analytical work to improve...


Evaluating earthquake geohazard using the Western Arctic Regional Network of Seismographs (WARNS)
chercheur principal: Schaeffer, Andrew
Année(s) de permis: 2024 2023 2022
Résumé: This licence has been issued for the scientific research application No.5310. This project aims to better characterize tectonic activity and evolution across the study region through improved monitoring of earthquakes and GPS motions. Using a temporary network of seismometers, the research team will produce an updated catalogue of earthquakes targeting more precise locations and depths, frequen...


Paleozoic rift history of Laurentia as recorded in Alaska, NWT and Yukon
chercheur principal: Cobbett, Rose
Année(s) de permis: 2021
Résumé: This licence has been issued for the scientific research application No.4696. The objective is to use geochemistry (composition of rocks) and geochronology (dating of rocks) to characterize volcanic rocks in order to better understand the environment that they were formed in and in turn learn about the tectonic history of western North America through Paleozoic time (~541 - 252 Million years). ...


Paleozoic rift history of western Laurentia as recorded in Yukon-NWT-Alaska
chercheur principal: Cobbett, Rose
Année(s) de permis: 2019
Résumé: The objective is to use geochemistry (composition of rocks) and geochronology (dating of rocks) to characterize volcanic rocks in order to better understand the environment that they were formed in and in turn learn about the tectonic history of western North America through Paleozoic time (~541 - 252 Million years). Results will be published in a series of Yukon Geological Survey publications, se...


Paleoproterozoic tectonometamorphic architecture of the south Rae craton
chercheur principal: Thiessen, Eric
Année(s) de permis: 2017
Résumé: The project goals are to visit an area of known exposed bedrock in southeastern Northwest Territories to produce a detailed geological map documenting rock type, structure, and metamorphic style. This work requires geological mapping and rock sample collection. A field camp consisting of single person tents will be set up as a low impact staging area for mapping. Mapping will be conducted by f...


Stratigraphy of the Hyland Group, Selwyn Mountains
chercheur principal: Turner, Elizabeth C
Année(s) de permis: 2013
Résumé: This project seeks to understand the ancient marine environments recorded in these rocks, and thereby to interpret this poorly known, dramatic time in North America’s tectonic evolution. The areas addressed will be those that were briefly described in 1993: 1 location is in Yukon Territory (YT) and 2 are in Northwest Territories (NWT). This work will complement licensed research currently under wa...


Magnetotelluric survey in northern British Columbia and the Yukon
chercheur principal: Jones, Alan
Année(s) de permis: 1999
Résumé: The objective of the study is to investigate the structure and composition of the earth's crust and upper mantle to depths greater than 60 km in northern British Columbia, NWT and BC. At eight locations along NWT hwy. 7, sensors will be lowered into small (1 m long x 25 cm wide x 25cm deep) holes dug in the ground . These sensors will measure the time variations of the Earth's natural electrical ...


Magnetotelluric Studies along the Lupin Mine winter road - Phase II
chercheur principal: Jones, Alan
Année(s) de permis: 1999 1998
Résumé: The objective of the study is to investigate the structure and composition of the earth's crust and upper mantle to depths greater than 200km along the Lupin Mine winter road east from Yellowknife to Contwoyto Lake. At approximately 20-25 locations along the 600 km winter road, sensors will be lowered through small holes drilled through the ice onto lake bottoms. These sensors will measure the tim...


Thematic Structural Studies in the Slave Province
chercheur principal: Bleeker, Wouter
Année(s) de permis: 2000 1999 1998 1997 1996 1995 1994
Résumé: Researchers will conduct routine geological research out of small mobile camps by means of traverse and boat work. The researchers will observe and describe bedrock geology at a large number of sites. This will be done in order to gain an understanding of the geological and tectonic history of the Slave structural province....


Licence #5136
chercheur principal: Lambert, Anthony
Année(s) de permis: 1985
Résumé: To measure crustal deformation in North America leading to a better understanding of earthquakes and plate tectonics. Measurements will be made by the technique of long-baseline interferometry using a mobile radio telescope. (Continued from last year.)...
