| Abstract: | Main rock types of Amushan formation in the section of Shangdan are crystalline limestone,bioaccumulated limestone,and have mound-like organic reef,rich in brachiopods,echinoderms fossils,massive bioclastic shoal.The main types of sedimentary facies are plateau facies and platform edge shallow facies.Geochemical characteristics indicate that sedimentary environments is semi-closed over salty water environment of oxic dolomite rock flats. |
