| 摘 要： | 利用岩层中的地球化学差异对地层进行划分是地层学的研究方法之一。本文利用在区调工作中获得的较为系统的岩石光谱半定量全分析数据,采用有序样品最优分割法和对分移动窗口法,对新疆温都哈拉一带的古生代地层进行了化学地层划分,并与野外根据宏观岩性特征划分的岩石地层单位进行了比较。

| Abstract: | It is one of the stratigraphical methods using the geochemical differences in strata for stratigraphic division.In the present paper,the Palaeozoic strata in the Wenduhala region,Xinjiang are chemostratigraphically divided based on the systematic data of spectral semiquantitative analysis obtained from the regional geological survey by means of the optimal partitioning method and the half moving window method for the ordered sample analysis.The results of the chemostratigraphic division are comparable with those of the lithostratigraphic division based on the macrolithologic characteristics. |
