Geochemical and isotopic studies of Acasta Gneiss Complex, the oldest terrestrial rock on Earth
Principal Investigator: Lee, Seung-Gu
Licenced Year(s): 2017
Summary: The objective of this project is to collect rock samples from the Acasta Gneiss Complex, the oldest terrestrial rock on Earth, and to find a geochemical proxy which can shed light on the studies of early Earth rare earth element geochemistry and cosmochemistry. The field research will be carried mostly spot to spot based on the published geologic maps of previous researchers. The research team ...


Examining the Acasta Gneiss Complex: A Broader Scope
Principal Investigator: Belosevic, Mike
Licenced Year(s): 2016 2015
Summary: This study is designed to encompass the following goals: 1) Collect samples from the expanded Acasta Gneiss Complex (AGC) study area; 2) Perform field mapping and general exploration of the expanded study area; 3) Perform age dating and isotopic analysis of the collected samples along with whole-rock geochemistry to compare data with those in the extensively studied AGC body adjacent to the Acasta...


Tracking environmental change in the Neoproterozoic Sheepbed and Keele Formations, Mackenzie Mountains, Northwest Territories, Canada
Principal Investigator: Sperling, Erik A
Licenced Year(s): 2014
Summary: The objective is to collect high quality and high resolution stratigraphic and sedimentological data of the Sheepbed and Keele Formations at their type localities, along with accompanying samples for geochemical and petrological analysis. Specifically, the overall goal is to understand how these formations at their type sections relates to their correlatives throughout northwestern Canada, and det...


Reconnaissance Study of Smoking Hills
Principal Investigator: Dunfield, Peter F
Licenced Year(s): 2013
Summary: The objective of this work is to conduct a one day reconnaissance study of the Smoking Hills area. Mineral, rock, water and soil samples will be collected. Geochemical properties and microbial communities will be analysed in the laboratory in order to characterize any potential features unique to this site that would warrant future, more detailed research. The site will be accessed by helicopt...


Mineralogy, Geochemistry, and Fluid Inclusions of the Caribou Lake Layered Mafic-Ultramafic Intrusion
Principal Investigator: Neyedley, Kevin
Licenced Year(s): 2013
Summary: The purpose of the study is to examine the rocks near Blachford lake lodge to gain a better understanding of how they formed and why there are there. Initial mapping has shown that they are unusual with more iron and nickel in them than would be normally expected and we would like to look at them to better understand their history. There have been exploration companies interested in these rocks an...


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) ...


The Search for Early Fossil Sharks in Lower Devonian rocks of the Mackenzie Mountains, NWT
Principal Investigator: Wilson, Mark V.H.
Licenced Year(s): 2013 1998 1996 1990
Summary: The 2 objectives of this research project are: 1) to recover some of the oldest-known body fossils of sharks and their relatives as well as other associated fossils. The anatomy of the fossil species will be described in detail and published in international journals. These fossils will allow identification of fragments of related species found at other sites worldwide, and will allow the researc...


The cumulative impacts of rapid environmental change in the northwestern NWT: Investigating the impacts of mega-slump disturbances on terrestrial and aquatic ecosystems in the lower Peel watershed, NW
Principal Investigator: Lacelle, Denis
Licenced Year(s): 2013 2012
Summary: This is a multidisciplinary project involving communities, governments and academic researchers. The goals are to : 1) inventory and track broad scale changes in landscape disturbances; 2) determine the impacts of natural and anthropogenic disturbances on the physical and chemical characteristics and ecology of streams and rivers; 3) determine disturbance thresholds relevant to the health of strea...


Geochemical and mineralogical controls on the low-temperature aqueous mobility of rare earth elements (REE) in mine waste from the Nechalacho deposit, NWT
Principal Investigator: Purdy, Colin
Licenced Year(s): 2012
Summary: The objective of this study is to determine what controls whether rare earth elements are mobile under low temperature and moderate to high pH conditions. Four 55 gallon barrels cut in half will be set up at Thor Lake with mine tailings in them. The tailings will be allowed to weather in the local environment. Samples of the tailings and waters in them will be sampled at the beginning, and then...


Investigating the Influence of Archean Seawater Composition on the Evolution and Diversity of Microbial Metallo-Enzyme Evolution Through the Chemistry of Archean Banded Iron Formation
Principal Investigator: Mloszewski, Aleksandra M
Licenced Year(s): 2011 2010
Summary: The recent discovery of new occurrences of Neoarchan (2.8 Ga to 2.6 Ga) banded iron formations (BIF) in the Northwest Western Territories have opened an exceptional opportunity to study ocean chemistry. In this regard, the research group has been engaged by the Northwest Territories Geoscience Office (NTGO) to undertake field and laboratory studies of Archean and Proterozoic Banded Iron Formation ...
