摘要
综述了国内外学者对等深流及其沉积物的研究现状。全面介绍了等深流的概念、等深流沉积物的特征以及研究意义和存在问题。等深流沉积是深水牵引流沉积中的一种重要类型。从产状、成分、结构、沉积构造、垂向层序和与海平面变化的关系等方面总结了等深流沉积的若干鉴别标志以及与其他类型深水沉积的区别。
A summary of new developments in the studies of contour currents and con-tourites,this paper introduces the conception of contour current,contour current sedimentation in modern seas,characteristics of contourites,as well as the significances and problems in the studies.A contourite is an important type of deep water traction current deposits.According to the occurrence,composition,texture,sedimentary structure,vertical succession of contourites and their relationship with the sea level,some discriminating features of contourites are summarized to distinguish them from other types of deep water deposits.
