摘要：

湖南石门杨家坪下寒武统存在两种沉积组合:其一由正常原地沉积、重力流沉积组成深水沉积组合;其二以牵引流为特征的浅水沉积组合。从早至晚由深海盆地→盆地边缘→台地前缘斜坡、台地边缘浅滩→潮坪构成一个由深变浅的沉积序列。

Abstract:

Two sedimentary complexes developed in the Lower Cambrian at Yangjiaping,Shi-men,Hunan Province.The first is a deep-water association constituted by marine au-tochthonous deposits and gravity flow deposits.The second is a shellow-water association constituted by tractive current deposits and algal stromatlite deposits.According to the se-quence of the section,it is concluded that the Early Cambrian from early to late period underwent the evolution process of deep sea basin→basin margin→platform foreslope→shallow beach→tidal flat,and formed a sedimentary sequence from deep to shallow water.
