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