The Grand Forks Complex and Kettle River Fault Zone, SE British Columbia: metamorphic contrast, timing and tectonic significance
For his PhD Joel examined the Kettle River Fault, an Eocene normal fault that bounds the east margin of the high grade Grand Forks - Kettle Dome complex, one of several metamorphic core complexes that comprise the Shuswap domain of SE BC. He examined the metamorphic P-T conditions and age of metamorphism of the hangingwall and footwall to the fault, the depth contrast across the fault, the nature of the fault zone, and its broader significance in the context of the tectonic evolution of SE BC. His study expanded on a smaller scale study by Pattison's MSc student Justin Laberge on the Granby Fault, which bounds the west margin of the Grand Forks complex.
