Transpression between two warm mafic plates: The Queen Charlotte Fault revisited

Creator:

Rohr, Kristin M. M., Scheidhauer, Maren, and Tréhu, Anne Martine

Abstract:

The Queen Charlotte Fault is a transpressive transform plate boundary between the Pacific and North American plates offshore western Canada. Previous models for the accommodation of transpression include internal deformation of both plates adjacent to the plate boundary or oblique subduction of the oceanic plate; the latter has been the...

An Abrupt Transition in the Mechanical Response of the Upper Crust to Transpression along the Queen Charlotte Fault

Creator:

Tréhu, Anne M., Scheidhauer, Maren, Rohr, Kristin M. M., Tikoff, Basil, Walton, Maureen A. L., Gulick, Sean P. S., and Roland, Emily C.

Abstract:

The Queen Charlotte Fault (QCF) is a major strike-slip fault that forms the boundary between the Pacific and North American plates from 51° to 58° N. Near 53.2° N, the angle of oblique convergence predicted by the Mid-Ocean Ridge VELocity (MORVEL) interplate pole of rotation decreases from >15° in the...
