Objective(s): To understand the ancient marine environments recorded in rocks, and thereby to interpret this poorly known, dramatic time in North America’s tectonic evolution.

Project Description: This project seeks to understand the ancient marine environments recorded in these rocks, and thereby to interpret this poorly known, dramatic time in North America’s tectonic evolution. The areas addressed will be those that were briefly described in 1993: 1 location is in Yukon Territory (YT) and 2 are in Northwest Territories (NWT). This work will complement licensed research currently under way on slightly younger rocks exposed farther north in western NWT near the YT boundary. The sedimentary rocks will be measured with a measuring stick and described incrementally through the layers exposed at each location (only one of which is in YT). The data will be recorded by hand in a notebook. Fist-sized samples will be collected using a small rock hammer for later geochemical analyses aimed at understanding the geochemistry of paleo-sea-water (a tool for telling time in ancient rocks; total = 75 kg). The work will be undertaken by two people (principal investigator and 1 student) from a simple base camp (two 2-person tents) placed by helicopter. No motorized equipment, dangerous chemicals, or explosives will be used, and all work will be done on foot. This project will contribute basic knowledge of western NWT's bedrock geology, which is poorly known. Better geoscience knowledge permits better policy development and is essential to long-term economic development. The work will initially be presented at the Yellowknife Geoscience Forum. Eventual publication(s) in scientific journals will be forwarded to the Aurora Research Institute (approximately 1-3 years after end of field work). The fieldwork for this study will be conducted from June 25, 2013 to August 31, 2013.
