Fig. 7From: Coupled onshore erosion and offshore sediment loading as causes of lower crust flow on the margins of South China SeaCartoon representation of lower crustal flow driven by coupled on shore erosion and offshore loading. Offshore basin structure from Sun et al. (2008), showing reflectors at 10, 21, 30, and 36 Ma and basement at 45 Ma. Crustal thickness is derived from seismic refraction data of Nissen et al. (1995). Black arrows indicate laminar flow in the quartz-bearing mid crust while gray arrows show slower ductile flow in the feldspathic lower crustBack to article page
