Fig. 1From: Coupled onshore erosion and offshore sediment loading as causes of lower crust flow on the margins of South China SeaSchematic strength profiles for the different types of crust in the South China Sea. a Strong crust offshore southern Hainan, b typical crust of southern China before rifting with thick weak middle crust, c crust under the Baiyun Sag at the time of low crustal flow. Strength is shown as the stress difference during deformation (σ − d). Modified from Burov and Watts (2006)Back to article page
