| 摘 要： | 为了认识中新世以来长江、黄河流域沉积物中黏土矿物的时空变化及古气候意义,利用X射线衍射方法分析了中新世以来长江下游河湖相沉积物、黄土高原红黏土和黄土-古土壤的黏土矿物组成.结果表明:中新世以来长江下游、黄土高原沉积物的黏土矿物组成都为伊利石+绿泥石+高岭石+蒙脱石;各地质时期长江下游和黄土高原不同剖面沉积物由不同的黏土...

| 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 consist... |
