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。
昌平組下部角礫狀碳痠鹽巖有兩類成因，分彆為風化殘積角礫巖和重力流角礫巖，其成因機製為由檯地嚮斜坡過渡的緩坡重力流形成。

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.
