摘要
运用1:20万水系沉积物测量中多种元素的背景含量对浅覆盖区的主要地质体和线形构造进行尝试性划分.通过对区域化探资料的整理分析,依据地球化学示踪作用原理,运用多元素背景判别法,较好地圈定了存在元素含量差的地质体和线性构造,提高浅覆盖区区域地质填图成果的信息承载量.
The background contents of various elements obtained from 1：200000 water system measurements was applied to trial division of major geological bodies and linear structures in shallow-covered region. Through sorting and analysis of regional geochemical data, and on the basis of the geochemical tracing principle, multi-element background differentiation method has been well used to delimit geological bodies and linear structures with differences in contents of elements and enriched the information carded in the results of regional geological mapping in shallow-covered region.
