摘要

内蒙西南部石炭系广泛发育碎屑岩-碳酸盐岩混合沉积

可划分出五种类型

其形成的陆源物质供给量、海岸性质、泻湖开放程度、事件作用的特点均不相同

其中事件性作用是贯穿整个混合过程的主线

致使滨海、内陆架浅海和外陆架浅海的混合沉积又各具特色

以内陆架浅海区的混合沉积发育最佳.

Abstract

Mixed siliciclastic and carbonate sediments are distributed extensively in Carboniferous strain in Inner Mongolia and could be divided into five types. Their formation related to sediment sources

the openness of lagoon

coastal feature and the effect of events. The effect of events continued throughout the whole mixing process

and thus causing the mixed sediments that formed in beach-shallow marine environment

inner continental shelf and outer the shelf to differ from each other. The best one is the mixed sediment formed in inner continental shelf environment.
