Summary(Plain Language Summary, not published)
This report presents preliminary results and models developed through GEM2 program on the ancient oceanic crust in British Columbia and Yukon. It details the distribution and characteristics of the various rock packages on the basis of field and laboratory analyses. It compares these data to modern analogues. The results presented herein help progress GEM2 model to ultimately redefine the regional tectonic models of the Cordillera.
