Research on Sedimentary Palaeoenvironments of the Sanmianjing Formation in Zhengxiangbaiqi, Mongolia

Abstract:

In Zhengxiangbaiqi, the Sanmianjing Formation of Middle Permian exposes most completely. The Lithology is mainly clastic rocks, in the lower part of the section, there are 60m gray middle-thick-bedded limestone. Based on detailed measurement of the Elitu Pasture Ⅱ, indoor research, identifications with microscope, paleontology and sequence stratigraphy studies, explored sedimtentary facies and sedimentary paleoenvironment of the Sanmianjing formation. The lower part and the upper part of Sanmianjing formation might be deposited in a shore setting with a high energy, and the middle part might be formed in an epicontinental sea with a relative low-energy. Fossils and sedimentary facies further enrich the biological face of the section, and prove new informations for contrasting between different stratigraphic and plaeoenvironment. This study proved principal geological data for further research on palaeogeography, oil and gas exploration.
