摘要
通过分析银川盆地 Y1孔地球化学元素含量及其分布规律 ,参考地层岩性等因素 ,确定了该盆地第四系地层地球化学元素的分带。依据地球化学元素分布 ,结合孢粉分析成果探讨了银川盆地第四纪中、晚期以来的沉积环境和古气候及其演化规律。
From an analysis of the contents of geochemical elements and their vertical distribution of the core samples from Yinchuan Basin and the stratigraphic lithologies a zonation of the geochemical elements has been determined. Combining this with spare pollen data,a discussion of the paleoclimate and paleoenvironment and their evoluation in the basin. Since the middle and late Quaternary has been maded.
