| Abstract: | The Middle Jurassic Buqu Formation in Zaring,Qiangtang,Xizang consists mostly of a succession of carbonate rocks in which brachiopods,bivalves and foraminifera occur on a wide range of scales.The present paper deals,in details,with the sedimentary facies analysis,correlation and mapping of individual sections,vertical sedimentary sequences and lateral variations in sedimentary faices belts,and palaeogeographic evolution of the Middle Jurassic Buqu Formation in Zaring,Qiangtang,Xizang. |
