主　　题：In With a Discussion of the Lowermost Marine Horizon of the Cretaceous in the Western Tarim Basin The Depositional Environment of the Cretaceous Kizilsu Group in Xinjiang 

摘      要：In this paper. it is demonstrated that there exist marine horizons in the upper part of the lower subcycle and the upper subeycle of the Kizilsu Group in Xinjiang. based on new evidence of authigenic glauconite. boron content. carbon and oxygen stablc isotopic analyses. and lithological and sedimentary features. The up- per part of the lower subeycle is the lowermost marine horizon of the Cretaceous in the western Tarim Basin, which is inferred to be of Barremian age.
