Figure F10. Change in plate geometry over time. A. Effect of subduction erosion (from von Huene and Lallemand, 1990). B. Overall estimation of plate geometry relative to the Asian continent (locations of the VF [volcanic front] relative to arbitrary origin on the Asian continent are given at bottom right) assuming constant (~100 km) depth to the subducting plate boundary from VF and past VF locations (Fig. F9, ). The VF and TA (trench axis) for each period are shown with their age. Plate geometry at 25 Ma is not certain, and two probable geometries are shown.
