THE GEOCHEMICAL ELEMENT CHARACTERISTICS AND PALEOSEDIMENTARY ENVIRONMENT OF THE QUATERNARY DEPOSITS IN YINCHUAN BASIN
-
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。

Abstract: 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. -
