Evidence for underthrusting beneath the Queen Charlotte margin, British Columbia, from teleseismic receiver function analysis


, : Evidence for underthrusting beneath the Queen Charlotte margin, British Columbia, from teleseismic receiver function analysis. Geophysical Journal International 171(3): 1198-1211

The Queen Charlotte Fault zone is the transpressive boundary between the North America and Pacific Plates along the northwestern margin of British Columbia. Two models have been suggested for the accommodation of the 20 mm yr-1 of convergence along the fault boundary: (1) underthrusting; (2) internal crustal deformation. Strong evidence supporting an underthrusting model is provided by a detailed teleseismic receiver function analysis that defines the underthrusting slab. Forward and inverse modelling techniques were applied to receiver function data calculated at two permanent and four temporary seismic stations within the Queen Charlotte Islands. The modelling reveals a 10 km thick low-velocity zone dipping eastward at 28 degrees interpreted to be underthrusting oceanic crust. The oceanic crust is located beneath a thin (28 km) eastward thickening (10 degrees ) continental crust.
