碳酸盐岩成岩作用与层序地层学关系研究--以鄂尔多斯盆地寒武系为例

本文从准同生成岩作用、成岩作用类型及其强度、成岩环境演化等方面探讨了成岩作用与海平面升降、层序地层学的关系。研究指出，准同生期成岩作用反映海平面升降、层序界面的形成最敏感；成岩作用的类型及其成岩强度反映了海平面升降幅度、层序边界的类型：体系域的演化控制了成岩环境的演化，不同的体系域其成岩作用类型及其组合不同。成岩作用研究在白云岩地层中对层序边界及其类型的识别、体系域的划分具有重要的意义。

Carbonate diagenesis and sequence stratigraphy: an example from the Cambrian strata in the Ordos Basin

The relationship between diagenesis and sea level changes and sequence stratigraphy is discussed on the basis of penecontemporaneous diagenesis, diagenetic types and strength and diagenetic conditions. The results of research show that: (1) the penecontemporaneous diagenesis is relatively sensitive to sea level fluctuations and the formation of sequence bounding surfaces; (2) diagenetic types and strength may indicate the amplitudes of sea level rise and fall and the types of sequence boundary, and (3) the evolution of diagenetic environments may be controlled by the evolution of systems tracts. It follows that diagenesis may be of great importance to the recognition of sequence boundaries and types in the dolostone strata and to the division of systems tracts.
