摘要
本文在岩石地层单位划分的基础上，应用微量元素特征研究为依据．讨论了沙尔布尔地区1：50000区调地质填图中地层组段划分的合理性，分析了各组间的相互关系，沉积环境变迁和沉积物源小性质．
On the basis of rock-stratigraphic units, rationality of dividing formations and members in regional geological surveying and mapping in shaerbuer area is discussed, relationship among different formations,change of depositional environmcnts and property of material resources are analysed with the characteristic of trace elements.
