| 摘 要： | 昌平组下部角砾状碳酸盐岩有两类成因,分别为风化残积角砾岩和重力流角砾岩,其成因机制为由台地向斜坡过渡的缓坡重力流形成。

| Abstract: | The genesis of breccia carbonate rocks in lower part of Changping Formation can be divided into 2 types, which are separately 1. the weathering sedentary breccia; 2. the gravity flow breccia. The genetic mecha- nism is the gentle slope gravity flow in transition from platform to slope. |
