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...

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. This project team will establish small 2-3 person camps on or near a mountainside which is already known, based on previous work, that the rocks they are interested in will be exposed. E...

Année(s) de permis: 2009
Résumé: This year, the research purpose is to investigate potential geological localities for work next year, so direct involvement with local communities and guides will be minimal. The researcher intends to identify and talk with people who have outfitting and guide businesses, and those who have knowledge of potential research areas for next summer’s research. The objectives of the proposed researc...

Résumé: The Sekwi Mapping Project is aimed at defining the structural, stratigraphic, metallogenic and geochronological characteristics of the bedrock of a segment of the Mackenzie Mountains. The project will also involve assessment of the mineral, diamond and hydrocarbon potential of the area. This information will provide an updated geological database that will include a GIS-based compilation of bedroc...

Année(s) de permis: 2002 2001 2000
Résumé: The research team will resume mapping bedrock and surficial geology at 1:50,000 and 1:250,000 scales, continuing a project begun in the summer of 2000. The base of operations will be either at Fort Liard, or at an existing base camp on the southeastern La Biche River. Fly camps will be accessed by helicopter. Fly camps will be visited by 2-4 crew members for about 1 week. From the fly camps the ...

Année(s) de permis: 1997
Résumé: 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...

Année(s) de permis: 1996 1995
Résumé: The researchers will achieve detailed mapping of granite- metasediment contacts by relying on detailed documentation of mineral asseblages, textures, metamorphic grade, and relative timing of the meta-sedimentary and meta-igneous rocks in the MacNaughton Lake area. Isotope U-Pb studies of granite and metasediment minerals will be used to constrain the absolute timing of intrusion and metamorphism....

Année(s) de permis: 1994 1992 1991
Résumé: Rock samples will be collected for processing in the lab. Some of these rocks will be processed for fossils (primarily silicified trilobites) which will be photographed and described for classification purposes. The data gathered will then be used for understanding the ancient (350-450 million years ago) ecology and the correlation of these rocks. Levels where there are extinctions followed by e...

Année(s) de permis: 1994 1993
Résumé: The bedrock geology of this area preserves a record of geological processes which occurred over 2 billion years ago, a collision of the continental margin (including Lake Harbour rocks) with another continental block and this resulted in a mountain belt. The eroded ancient mountain belt (the Lake Harbour rock) will be examined to determine the age of the rock to better understand the continental m...

Année(s) de permis: 1996 1994 1993 1992 1991
Résumé: The research will involve measuring the thickness of the rocks, identify the rock types, observe the structures within the rocks and collect samples for additional laboratory analyses. Most of the work will be conducted using helicopter support out of Inuvik and Tuktoyaktuk, visiting the sites on a daily basis. If some sites require more than one day's work I will set up a small two-man camp for t...
