Résumé: This licence has been issued for the scientific research application No.5354. The research team aim to conduct a detailed paleomagnetic study of the 2.7-billion-year-old Kam Group at the Giant section, ~ 5 km north of the city of Yellowknife. The intention of the project is to constrain the paleogeographic location of the Slave craton in the Archean and its relationship with other coexisting cr...

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...

Résumé: This continuing research addresses the history of Earth-surface environments between about 1 billion and 700 million years ago. The objective for 2019 is to obtain field measurements and samples. A base-camp of two people will be deployed by helicopter, and all work done on foot. Working on mountainside rock exposures, the research team will collect fist-sized samples for later geochemical anal...

Année(s) de permis: 2015 2012
Résumé: This project seeks to carry out the first detailed study of the newly discovered Tunnunik impact structure, located on Victoria Island, NWT. The research team will carry out field mapping and conduct gravity, ground magnetic, and seismic surveys, and sample for paleomagnetic studies. They will also ground-truth a remote predictive map generated with Radarsat-2 and other satellite data. The goal...

Résumé: The present study aims to obtain information with the following objectives: 1) further describe, sample, and document field relationships and structures present in areas that were sampled and found to be significantly old (>3.8 billion years); 2) explore and sample other units which based on field relationships and mineralogy are likely to be as old or older than previously documented samples; 3) ...

Année(s) de permis: 2013
Résumé: The primary objectives are to i) collect fossils (i.e. peat, bone, wood, and other sedimentary proxies) for paleoenvironmental reconstructions and, ii) document the age of the Beaufort Formation (Fm) at Ballast Brook, northwest Banks Island using a new approach based on the exposure of quartz sand grains to cosmic radiation: terrestrial cosmogenic nuclide (TCN) burial dating. The cosmogenic nuclid...

Année(s) de permis: 2013 2012
Résumé: This is a Masters of Science research project aimed at understanding the geological evolution of a deep-marine environment that existed in the northern Mackenzie Mountains between 500 and 450 million years ago. The project team will establish small 2-3 person camps on or near a mountainside where we already know, based on previous work, that the rocks they are interested in will be exposed. Eac...

Résumé: The research team proposes to revisit Duck Hawk Bluffs (DHB), southwest Banks Island, the “type section” for the formerly reported subsurface record. DHB offers an exceptional exposure along the north shore of Thesiger Bay, measuring 8 km long and up to 60 m high. Previous work assumed that the bluffs were composed of an undeformed “layer-cake” stratigraphy recording discrete depositional events ...

chercheur principal: Rainbird, Robert H
Année(s) de permis: 2007
Résumé: This study aims to describe the formation of a very large depression that covered most of north-western Canada 1.7 billion-years ago. This will be helpful to understand the geological evolution of the Canadian Shield, and ultimately, how Earth formed, how it changed through time and how it will evolve in the future. The researchers will be using transportation (helicopter and fixed wing aircr...

Année(s) de permis: 2003 2002
Résumé: The purpose of this study (2003 component) is to examine the fossilized types of corals that are found in the regional geological formations. Locally these corals coalesced to form mini-reefs, with interesting ecological characteristics. From the study...
