| Abstract: | Clay minerals in the outcropped sandstone from Lower Cretaceous Chengzihe Formation and Muling Formation in Jixi Basin were analyzed by X-ray diffraction.The results show that the clay minerals mainly consist of illite,kaollinite and illite/smectite,which can be divided into two types: kaolinite-and illite/smectite types.The outcropped sandstone occurred in middle diagenetic stage-A on the basis of the clay mineral composition.The development factor of the formation of kaolinite type clay mineral is caused ... |
