为了研究青海省鄂拉山地区找矿远景,基于该区最新一轮1∶5万水系沉积物测量数据,提炼分析其地球化学特征之元素分布特征、元素组合特征、元素异常特征,认为该区主要成矿元素为 W,Sn,Mo,Bi,Ag,Cu,Pb,Zn,Au, Sb；并指出该类成矿元素多在元古宙和古生代的地层中明显富集；主要成矿类型为矽卡岩型和热液充填型。结合已知成矿地质条件,最终优选出4个找矿远景区,为该区域提供了较明确的找矿方向。
為瞭研究青海省鄂拉山地區找礦遠景,基于該區最新一輪1∶5萬水繫沉積物測量數據,提煉分析其地毬化學特徵之元素分佈特徵、元素組閤特徵、元素異常特徵,認為該區主要成礦元素為 W,Sn,Mo,Bi,Ag,Cu,Pb,Zn,Au, Sb；併指齣該類成礦元素多在元古宙和古生代的地層中明顯富集；主要成礦類型為矽卡巖型和熱液充填型。結閤已知成礦地質條件,最終優選齣4箇找礦遠景區,為該區域提供瞭較明確的找礦方嚮。

In order to study the prospects in Elashan area of Qinghai province,based on the latest stream sediment survey data with the scale of 1∶50000,and the study on characteristics of element distribution, assemblage and anomaly,it is regarded that major ore forming elements in this area are W,Sn,Mo,Bi, Ag,Cu,Pb,Zn,Au and Sb.It is pointed out that these ore forming elements are usually concentrated in Proterozoic and Paleozoic strata obviously,and major ore forming types are skarn type and hydrothermal vein type.Combining with the already known geological condition of mineralization,4 areas with good ore prospects have been selected.It will provide clear suggestions for the further prospecting work in this area.
