Neoproterozoic stratigraphy, Mackenzie Mountains
Principal Investigator: Turner, Elizabeth C
Licenced Year(s): 2017
Summary: This continuing research addresses the history of Earth-surface environments between about 1 billion and 700 million years ago. The objective for 2017 is to complete the sample suite being used by a PhD student (most of the required samples are already in-hand). A base-camp of two people will be deployed by helicopter, and all work done on foot. Working on mountainside rock exposures, the resea...


Geology of the Tunnunik impact structure, Victoria Island, NWT
Principal Investigator: Osinski, Gordon
Licenced Year(s): 2015 2012
Summary: 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...


Seawater and depositional variations across the Slave craton: insight from banded iron formation and associated rocks
Principal Investigator: Haugaard, Rasmus RH
Licenced Year(s): 2013 2012
Summary: In the previous year, research work were started on some of the new occurrences of 2.9 - 2.6 Ga old banded iron formations in the NWT. This opened an exceptional opportunity to study ocean chemistry directly preceding the Great Oxidization Event (GOE). In this regard, the research group has been engaged with the Northwest Territories Geoscience Office (NTGO) to undertake field and laboratory studi...


Petrogenesis of the Acasta Gneiss Complex: Ancient Rocks Revisited
Principal Investigator: Reimink, Jesse R
Licenced Year(s): 2014 2013 2012 2011
Summary: 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) ...


CaHiGeo Caribou Hills Geological History
Principal Investigator: LABROUSSE, Loic
Licenced Year(s): 2013
Summary: The objectives of the CaHiGeo project are to sample paleogene rocks for sedimentological and stratigraphical analysis and dating; to sample the underlying rocks for correlation with equivalent formations in Northern Yukon and dating; and to measure the possible deformation of the paleogene rocks at the inferred location of sealed faults (Eskimo Lake Fault Zone). The methods used in the field fo...


Reconstructing Pliocene Environmental Change and Landscape Dynamics using the Beaufort Formation on Northwest Banks Island, NT
Principal Investigator: Gosse, John C
Licenced Year(s): 2013
Summary: 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...


Stratigraphy of the Misty Creek Embayment
Principal Investigator: Turner, Elizabeth C
Licenced Year(s): 2013 2012
Summary: 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...


Environmental change at Duck Hawk Bluffs, SW Banks Island: from a forested to glaciated Arctic
Principal Investigator: England, John H
Licenced Year(s): 2012 2010 2009 2008 2007 2006 2005 2004 2003 2002
Summary: 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 ...


Geology of the Hornby Bay Basin
Principal Investigator: Rainbird, Robert H
Licenced Year(s): 2007
Summary: 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...


Sedimentology and Stratigraphy of Upper Devonian Strata around Hay River, NWT
Principal Investigator: MacNeil, Alex
Licenced Year(s): 2003 2002
Summary: 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...
