Objective(s): To determine the strength of the lower crust, and to investigate how stress varies across a typical lower crustal shear zone.
Project Description: The two main objectives for this project are to a) determine the strength of the lower crust, and b) investigate how stress varies across a typical lower crustal shear zone. These objectives will be achieved by examining a transect through an ancient lower-crustal shear zone. Two weeks of fieldwork will be carried out at the Great Slave Lake Shear Zone to acquire the appropriate samples to explore stress across a fault zone. The majority of the time will be spent collecting small (hand-sized) rock samples. Key sites, based on previous mapping of the area have been identified. Only a small amount of rock material is required, and no trace of the activities will be left behind. After the field work is complete, detailed microstructural analysis will be undertaken at the University of Oxford. This information can then be used to determine the strength of the lower crust, which will help to make more accurate models of ear... Show more
