摘要
The present progress in research on mixed rock of terrigenous clastics and carbonates is reviewed in this paper, mainly including classification, terminology, depositional environment, depositional modes and petroleum-gas geological significance. It is proposed by a comprehensive analysis that the depositional facies favorable for the mixed deposition mainly cover coastal and shallow-lake facies, following by shallow-sea shelf, shore-shallow lacustrine and delta facies. The study on the depositional environment implies that the factors controlling the development of coastal mixed-rocks include tidal effect, relatively strong hydrodynamic condition and a shallow sea environment favorable for the living of lower organisms.
