According to the sequence model, the topography is expanse and flatness, there are relative shallow water, stable structure, flattened basement in intercontinental rifting basin, and the provenances changed gradually from terrigenous clasts to intra-basin carbonate. So, there are some corresponding characteristics in sequence genetic framework:① Sequence material components are carbonate rocks, and mixed sedimentary series of carbonate rocks and clastic rocks.

就层序模型来讲，陆内裂陷盆地地势宽缓，具有水体相对浅、构造稳定、基底平缓、物质来源由陆源碎屑逐渐向盆地内的碳酸盐转化，因此，其相应的层序成因格架具有如下主要特征：①在层序物质构成方面，主要由碳酸盐岩构成，其次是碳酸盐岩—碎屑岩的混合沉积岩系。
