摘　　要：尚丹剖面阿木山组,以结晶灰岩、生物灰岩为主,其中有丘状生物礁体,含丰富的腕足、棘皮类生物化石,生物碎屑滩规模大,主要发育碳酸盐岩台地相及台缘浅滩相。地球化学特征显示沉积环境为富氧的海相云坪半封闭超咸水环境。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.
