Résumé: This licence has been issued for the scientific research application No.4723. The main object of this research project is to determine the strength of Earth's lower crust and how this portion of the crust responds to tectonic forces. Two weeks of fieldwork will be carried out at the Great Slave Lake Shear Zone to acquire the appropriate samples to explore stress across a fault zone. The majo...

Résumé: Sedimentary rocks of Cambrian age (~500 million years old) are the oldest Phanerozoic strata in the Mackenzie River valley region and record the spread of a shallow sea over much older strata. The approximate age of these rocks is known via trilobite fossils based on reconnaissance collections made in the 1960s and 2010s. The purpose of the project is to make more closely spaced fossil collections...

Année(s) de permis: 2019
Résumé: The objective of this research is to addresses the history of Earth-surface environments between 1 billion and 700 million years ago. The objective for 2019 is to complete a sample suite used by a Master of Science student. Each base-camp of 2 people will be deployed by helicopter, and after that, all work will be done on foot, with no motorised equipment. Working on mountainside exposures, the...

Année(s) de permis: 2018
Résumé: This year’s objective is to complete the work at the selected locations by obtaining a full suite of rock samples for analysis, photograph each location, and measure natural radiation. At each site, the rock exposure will be photographed in detail. Natural radiation will be measured every half meter using a sensor without major disturbance of the rock face. At each location, rock samples weigh...

chercheur principal: Rainbird, Robert H
Année(s) de permis: 2017
Résumé: Fieldwork is proposed to acquire geological observations and collect rock samples for laboratory analysis. Results of fieldwork in the area will contribute to acquiring state-of-the-art data, updated maps, and related publicly available publications. Work consists of visual examination, description, measurement, and photography of rock outcrops. GPS units and satellite imagery will be used to l...

chercheur principal: Lee, Seung-Gu
Année(s) de permis: 2017
Résumé: The objective of this project is to collect rock samples from the Acasta Gneiss Complex, the oldest terrestrial rock on Earth, and to find a geochemical proxy which can shed light on the studies of early Earth rare earth element geochemistry and cosmochemistry. The field research will be carried mostly spot to spot based on the published geologic maps of previous researchers. The research team ...

chercheur principal: Hickey, Kenneth A
Année(s) de permis: 2017 2016 2015
Résumé: The objective of this research project is to map the March Fault and the structures in the rocks that it cuts through to look for evidence of when it formed, how it formed, and how much relative movement has occurred along it. This research is primarily a field-based involving detailed geological mapping by foot along a series of traverses across the March Fault. The research team will use rock...

chercheur principal: Fiess, Kathryn M
Année(s) de permis: 2016
Résumé: To characterize the source rock potential of Devonian to Cretaceous age shales in the southern Peel Plateau. At each site, the rock exposure will be described in detail and photographed. Natural radiation will be measured every meter using a sensor. A small amount of rock (equivalent to size of a fist) will be sampled every meter. Additional samples of 1-2 kg may be collected for dating the age...

Année(s) de permis: 2016 2015 2014 2012
Résumé: This work is part of NRCan’s Geo-mapping for Energy and Minerals Program, designed to upgrade the geoscience knowledge base in Canada’s North to modern standards. A team of 10-15 scientists set up a temporary camp in the area of interest. Float planes, helicopter and boats are used to access remote areas. The research team will walk on the land and make observations, take notes and draw sketche...

chercheur principal: Belosevic, Mike
Année(s) de permis: 2016 2015
Résumé: This study is designed to encompass the following goals: 1) Collect samples from the expanded Acasta Gneiss Complex (AGC) study area; 2) Perform field mapping and general exploration of the expanded study area; 3) Perform age dating and isotopic analysis of the collected samples along with whole-rock geochemistry to compare data with those in the extensively studied AGC body adjacent to the Acasta...
