Neoproterozoic stratigraphy, Mackenzie Mountains
Principal Investigator: Turner, Elizabeth C
Licensed Year(s): 2019 2018 2017
Summary: 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...


Yukon-Northwest Seismic Network: Characterizing Earthquakes and Earth Structures
Principal Investigator: Audet, Pascal
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013
Summary: The objectives of this research project are: 1) to continue the detection and characterization of earthquakes occurring within the northern Canadian Cordillera (Mackenzie Mountains) and surrounding areas, which are one the most seismically active areas of Canada; and 2) to study the Earth structures at large depths (0 to 100 km) to understand the formation and evolution of the Cordillera. To this ...


Global and regional environmental signals of the Mississippian/Pennsylvanian strata in the Liard Basin Northwest Canada
Principal Investigator: Fedorowski, Jerzy A.
Licensed Year(s): 2019 2018
Summary: The principal aim of this project is to examine the settlement, development and decline of the fossil corals as a response to environmental conditions in the Liard region during Mississippian to Early Pennsylvanian times (358.9 to 314.6 million years ago). The study will be conducted against the background of the worldwide expansion of corals in the Viséan age (346.7 - 330.9 million years ago) and...


The Mackenzie Mountains Earthscope Project
Principal Investigator: Schutt, Derek L
Licensed Year(s): 2019 2018 2017 2016 2015
Summary: 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...


EarthScope Transportable Array
Principal Investigator: Busby, Robert W
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013
Summary: This project consists of a large deployment of ground motion sensors (~270 total) throughout Alaska and western Canada; 28 located in Yukon Territory and 5 in the Northwest Territory. Each station senses the ground movement from distant earthquakes and sends data via satellite or radio modem to a central receiving point in San Diego. The purpose of collecting these data is to study deep geologic s...


Marine Geohazard and Environmental Studies in the Southern Beaufort Sea
Principal Investigator: Dallimore, Scott R
Licensed Year(s): 2019 2018
Summary: 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 ...


Obtaining a strength profile of an exemplary lower crustal fault segment — the Great Slave Lake shear zone, Northwest Territories Canada.
Principal Investigator: Dyck, Brendan
Licensed Year(s): 2018
Summary: 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...


Shale Basin Evolution 2
Principal Investigator: Fiess, Kathryn M
Licensed Year(s): 2018
Summary: 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...


Structural Framework for the Cantung Tungsten Deposit and its Relation to the Regional Deformation History
Principal Investigator: Salmabadi, Ehsan
Licensed Year(s): 2018
Summary: 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, ...


2018 Richardson Mountains
Principal Investigator: Hadlari, Thomas
Licensed Year(s): 2018
Summary: 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...
