Abstract:

Turbidity current deposits were developed widely in Nanpanjiang Basin during the Middle Trias-sic.The sedimentary model is submarine fan.This is based mainly on that:1.They have the character-istics of turbidity current deposits.2.They have obvious channel deposits.3.The sequences of the tur-bidity are prograding turbidite fan in the texture profile.The sedimentary model of the turbidity current deposits in the area is not only submarine fan,but several fans with multi-source.
