摘要：

湖北荆门海慧沟上三叠统由九里岗组及王龙滩组组成,厚逾1100m,为一套层序清楚的河流沉积体。从下向上分别由辫状河→曲流河→辫状河→曲流河两个沉积旋回构成,其中,辫状河沉积物占绝对优势。

Abstract:

Upper Triassic at Haihuigou,Jingmen,Hubei Province consists of Jiuligang and Wanglongtan Formations which have a total thickness of more than 1100m.The sediments show clearly a set of fluvial deposit sequence constituted of braided river→meandering river→braided river→meandering river cycles from bottom to top.Among them,the braided river facies is dominant.
