Magmatism along Dawson Fault

Project Lead:  Maurice Colpron

Location:  Hart River and Coal Creek inliers

This study investigates the timing and style of Paleozoic magmatism along the Dawson fault corridor. Recent studies at the east of the Dawson fault (in the Rackla belt) have documented at least 4 distinct episodes of volcanism, but it is currently unclear how volcanic rocks to the west compare with those at Rackla. Establishing a more detailed framework for magmatism along the Dawson fault corridor will help refine interpretation of the evolution of this major structure and regional metallogenetic models. The new data will also help refine the bedrock geology compilation.
