The Mackenzie Mountains EarthScope project (MMEP) is funded under the EarthScope program of the U.S. National Science Foundation. This project is collaborating with the larger EarthScope USArray project, which will be studying seismicity (earthquakes) and earth structure in the broader northwestern Canadian and Alaskan regions, and with Canadian researchers from several agencies including the Yuko...

Résumé:
The research goals are to ascertain the formation of marine pock marks, which are circular depressions on the sea floor thought to have formed from the release of methane gas. The hypothesis is that these features are actively releasing gas to the atmosphere and that they are formed from the release of methane from degrading or thawing offshore permafrost. The research team intend to document the ...

Résumé:
The two main objectives for this project are to a) determine the strength of the lower crust, and b) investigate how stress varies across a typical lower crustal shear zone. These objectives will be achieved by examining a transect through an ancient lower-crustal shear zone.
Two weeks of fieldwork will be carried out at the Great Slave Lake Shear Zone to acquire the appropriate samples to exp...

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...

Résumé:
The objective is to conduct a structural analysis of the Cantung Tungsten Mine and its geological environment to: 1) reconstruct the deformation history responsible for fold geometry that hosts the Cantung tungsten deposit; and 2) understand how the deformation at Cantung is linked to deformation history of the surrounding area.
Research will be conducted through field mapping using a compass, ...

Résumé:
Some models for opening of the Arctic Ocean place Alaska against the Canadian Arctic Islands before Cretaceous time. Other models using orthogonal continental drift place the counterpart to the Canadian Arctic Islands in northern Russia. The two models predict very different structural dynamics at the potential hinge point of rotation and so the Richardson Mountains are a critical area for resolvi...

2017 Résumé:
The objective of this research is to improve the public understanding of bedrock geology of two regions of the Mackenzie Mountains, including folding and faulting, stratigraphic relationships, tectonic history, and economic mineralogy. This objective includes sharing geoscience information with all interested parties through the production and publication of bedrock geology maps and reports on the...

20172016 Résumé:
The objectives of this project are to update and increase the understanding of the geological history of an area along the Beaulieu River.
The work will be conducted mostly on foot with access to the shore provided by canoe and zodiac boat. Notes on the geology will be taken and entered into a database. Holes up to 1m in depth will be dug to make observations and take samples of the till, the h...

2017 Résumé:
Recent evolving thoughts on the geological history of the East Arm of Great Slave Lake require the area to be re-evaluated with respect to its structural and metamorphic history as well as to explain its metal endowment. This study seeks to evaluate the structural and metamorphic history of the area, and its potential to host economic mineralization.
Field investigations will examine exposures ...

Résumé:
This research will provide the geological information needed to correlate Cretaceous (<140 Ma) and younger geology of the Smoking Hills with that on Banks Island and elsewhere in the Canadian High Arctic and Mackenzie-Beaufort region. This will provide a greater understanding of the age and evolution of the offshore Canada Basin (Arctic Ocean). Studies of kimberlite indicator minerals will provide...
