... was taking place. Intra-oceanic subduction appears to have produced a mature island arc built on oceanic crust in some places (Luobusa), but resulted in lithosphere extension and the formation of ophiolites elsewhere (Xigaze), perhaps at the same time. The newly formed island arcs were probably the regions...
