The faulted terrace type steep slope break belt controlled the development of the fan-deltas and sub-aqueous fan system.

断阶型陡坡坡折带控制着扇三角洲或近岸水下扇及前方的湖底扇体系的形成和分布；

But in the north part of the sub-sag, controlled by the syn-sedimentary fault, steep fault-step was developed with mainly deposition of sub-aqueous fan, turbidity fan, and front of fan-delta.

北部为受生长断层控制的陡坡断阶带，以典型的水下扇、浊积扇和扇三角洲近端前缘沉积为主。
