摘要
本文描述了湘西黔东地区寒武纪沉积的等深岩类型和特征。对砂质等深岩和泥砂质等深岩层序的形成过程进行了讨论。分析了等深岩中交错层理反映的古流向资料,结合古地理背景,建立了工作区等深流沉积模式。
This paper describes the types and characteristics of contourites of Cambrian in Western Hunan and Eastern Guizhou. The forming process of sandy contourite and mud sandy contourite sequences are discussed. Based on the analysis of the palaeocurrent direction of cross-bedding in contourites and connecting with palaeogeographic setting,a sedimentary model of contourites in the study area is established.
