摘要
在1︰5万水系沉积物测量的基础上,对西藏妥坝地区的地球化学特征进行了初步研究。对元素的分散聚集特征、元素的组合特征、异常元素的综合特征进行了研究,发现Ag、Pb、Cu、Mo为区内具有一定找矿潜力的指示标志。根据元素地球化学特征,结合地质条件,圈定元素综合异常8处,对重点综合异常HS18和HS20进行评述,并据此划分3个找矿靶区,为下步找矿工作提供基础资料。
A preliminary study on geochemical features of stream sediments in the Tuoba area of Tibet,China has been carried out in this paper,based on the 1：50000 stream sediment survey,through analyzing characteristics of dispersion and aggregation of elements,combination features of elements,and comprehensive features of abnormal elements. Results show that Ag,Pb,Cu,and Mo are potential indicative elements for mineral exploration in the area. Based on the elemental geochemical characteristics of stream sediments and the geological background of the area,eight comprehensive geochemical anomalies have been outlined. In addition,two important comprehensive geochemical anomlies of HS18 and HS20have been checked and assessed and three favorable prospecting targets have been outlined. These work has provided good basic data for the further mineral exploration in the area.
