Exploration of the Earliest Crust Forming Events on Earth
Principal Investigator: Reimink, Jesse R
Licensed Year(s): 2016
Summary: This project will use radioactive isotope systems, whole rock isotopic measurements, and isotope data for zircons to investigate the role Hadean (> 4 billion year (Ga) old) crust played in the genesis of the Slave craton of the Northwest Territories, Canada. Data of this nature for rocks from the best-studied locality in the Slave craton, the Acasta Gneiss Complex, show that these circa 3.8-4.02 G...

Examining the Acasta Gneiss Complex: A Broader Scope
Principal Investigator: Belosevic, Mike
Licensed 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...

Petrogenesis of the Acasta Gneiss Complex: Ancient Rocks Revisited
Principal Investigator: Reimink, Jesse R
Licensed 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) ...
