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界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。
It is one of the stratigraphic methods of using geochemical difference in stratigraphic division. The Palaeozoic strata of the Wenduhala area, Xinjiang, is chemostratigraphically divided based on the systematic data of spectral semiquantitative analysis obtained from the regional geological surveying, using the method of optimal cut for orderly samples and the method of half moving windows. The results of the chemostratigraphic division are compared with the lithostratigraphic units based on the lithologic character.
