奔都-汤满地区水系沉积物地球化学特征及找矿

Stream Sediment Geochemical Characteristics and Prospecting in the Bendu-Tangman Region

对奔都-汤满地区16个元素水系沉积物测量地球化学特征研究,贫乏元素有Sn、Bi、Mo、W;正常元素有Pb、Ag、Hg、Au;富集元素有Zn、Cr、Sb、As;强富集的元素有Cu、Ni、Co、Cd。通过各元素时空分布研究,对主要地球化学异常进行推断解释,指出区内蛇绿混杂岩带、冈达概组二段是寻找Cu、Pb、Zn、Au、Ag等多金属矿的有利层位。

Stream sediment survey shows that the Bendu-Tangman region is rich in Zn,Cr,Sb and As,and highly rich in Cu,Ni,Co,Cd and depleted in Sn,Bi,Mo and W.The stream sediment geochemical anomalies show that the Second Member of the Gangdagai Formation and ophiolitic mélange are favorable mineralized horizon to search for Cu,Pb,Zn,Au and Ag ore deposits.
