Summary: For this research the Principal Investigator (PI) propses an innovative combination of quaternary geology, isotope geochemistry, and Precambrian geochronology that will identity previously unmapped outcrops of ancient continental crust in the Acasta Gneiss Complex (AGC). An age range and bedrock composition will be generated for the research area and used to help further the understanding of the p...

Principal Investigator: Lee, Seung-Gu
Licensed 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 ...

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...

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...

Principal Investigator: Komiya, Tsuyoshi
Licensed Year(s): 2015
Summary: The objectives are to conduct a geological survey and rock sampling in the Acasta Gneiss Complex to investigate evolution of the early earth. The Acasta Gneiss is the oldest rock in the world, and uniquely records the early earth. The Acasta Gneiss has many generations and a complex history including not only the magmatic formation with different ages but also deformations. Comprehensive works on ...

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) ...

Principal Investigator: Pepper Henry, James
Licensed Year(s): 2003
Summary: The goal of this project is to collect a sample of the Acasta Gneiss from the Slave Craton to be used to represent the peoples and indigenous communities of Canada on the grounds of the Smithsonian Institution's National Museum of the American Indian in...

Licensed Year(s): 2000 1999 1998 1997 1996 1995 1994
Summary: Map and describe the various rock types and assess their role in the complex geological history of the Slave Province. Fly-in / fly-out camps with small airplanes and small campsites to make daily traverses by boat or foot to study the local rocks. Small samples will be taken of interesting rocks; samples are fist sized....

Principal Investigator: Relf, Carolyn
Licensed Year(s): 1994 1993 1992
Summary: In this ongoing study, the researcher will examine the nature of the rocks found in the volcanic belt of the Avialik River area. This work will help to determine the amount of base metals and precious metals found in this belt of rocks. In addition, the movement of rocks (in the past) along a fault will be examined. Geological mapping (field work) will be done in the summer while analyses of the r...
