摘要:

大陆斜坡是联系浅水台地与深水盆地的枢纽地带,以包括巨大岩块在内的巨厚斜坡边缘型沉积为特征。黔南地区在中三叠世时,具有活跃的碳酸盐大陆斜坡沉积,按其性质,该期斜坡环境可分为沉积边缘型与跌积边缘型。它们主要受强烈而不均匀的断裂作用控制。在不同类型斜坡上,各种沉积作用标志也有较明显的差异。

关键词: 大陆斜坡, 沉积迎缘, 跌积边缘

Abstract:

The continental slope is the key zone connecting the shallow platform and the deep basin. It is of the feature of thick slope margin sediments including huge rock blocks. There was active carbonate continental slope sedimentation in the Middle Triaassic in south Guizhou, and according to their characteristics, the slopes could be divide into sedimentary margins and bypass margins. They were chiefly controlled by violent and non-uniform faulting. On different slopes there were obvious differences between the signs of the sedimentation.

Key words: Continental slope, Sedimentary margins, By-pass margins
