Sedimentary Characteristics and Geological Implications of the Middle Permian Tempestite in Moyang Section, Luodian, South of Guizhou
摘要
The Maokou Formation of Middle Permian in Moyang Section, Luodian, South Guizhou Province is mainly composed of marine shelf carbonates. Storm deposits include bottom erosional surface A and four sedimentary units: B,C,D,E. Four successions of storm deposits can be distinguished,correspondent to the water-depth and storm flow involved. The sedimentary characteristics, types and sequences of the Moyang storm deposit suggest that the preservation of the storm sedimentary sequence closely related to the sedimentary environment, providing a reference for understanding the evolution of the southern margin of the Yangtze carbonate platform.
