Abstract In order to investigate the temporal and spatial changes of clay mineral since the Miocene in the Yangtze and Yellow River reaches and their palaeoclimate implications, the X-ray diffraction analysis(XRD)was applied to study the clay minerals in the fluvial-lacustrine sediments in the lower reaches of the Yangtze River and the red clay-loess sequences in the Chinese Loess Plateau. The results show that the clay mineral compositions of the lower reaches of Yangtze River and Chinese Loess Plateau mainly consisted of illite, chlorite, kaolinite and smectite. During each geological stage, the sediments of different deposition profiles in the two study areas have different combinations of clay minerals. In each continuous depositional profile there exists a phenomenon that illite tends to gradually increase which reflects the gradual cooling of climate. The ratios of illite to kaolinite(Ill/Kao)and illite to smectite plus kaolinite(Ill/(Sm+Kao))may serve as a proxy to evaluate the palaeoclimate.
