... margin of the Aldan–Stanovoy shield and the Mongol–Okhotsk orogenic belt at their junction with the Sikhote-Alin orogen. The Sikhote-Alin orogen is recorded as a gradual west–east decrease in lithospheric thickness from 100 to 80 km, except in the Lower Amur region, in which the lithosphere thickens...
