In this paper, the sedimentary, geochemical and coal petrographic characteristics of the Upper Paleozoic Taiyuan and Shanxi Formations in Huanghua Depression are systematically analyzed. It is found that the formation process of Taiyuan Formation coal seam is greatly influenced by sea water. The overlapping relationship between limestone and its floor rock is a typical progressive transgressive sedimentary type. Geochemical data show that the limestone roof and floor strata are also formed in high salinity sedimentary environment, similar to the limestone development environment, which also shows that the transgression process in the study area is gradual, not sudden transgression.
