摘要

南盘江盆地中三叠世广泛发育一套浊流沉积

为海底扇模式:(1)具一般浊积岩特征;(2)水道沉积明显;(3)浊积岩剖面结构为推进型浊积扇剖面序列。不仅是海底扇

面且是多物源、多个浊积扇的堆积体。

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.
