青海省兴海县拉届亥地区矿体特征及成矿分析

Analysis of the Orebody Characteristics and Metallogenic in Lajiehai Area,Xinghai County,Qinghai Province

青海省兴海县拉届亥地区属昆秦接合部造山带,位于东昆仑造山带和西秦岭造山带的交汇部位,属鄂拉山华力西期—印支期铜、铅、锌、锡、金、银(钨、铋)成矿带。在对区内物、化探特征分析的基础上,着重探讨了区内成矿类型、控矿要素、找矿标志以及找矿方向,为区内找矿工作提供参考。

Lajiehai area of Xinghai county,Qinghai province is belongs to oroegne belt in the joint of Kunlun-Qinling,it is located the intersection part of east Kunlun orogenic belt and west Qinling oro-genic belt,which is belongs to the Cu、Pb、Zn、Sn、Au、Ag（W、Bi）metallogenic belt of variscan period -in-dosinian period.Based on analyzing the geophysical and geochemical characteristics of the research area, the metallogenic types and ore-controlling factors are discussed,besides that,the prospecting marks are summarized and the prospecting direction of the research area are also researched in depth.The above re-search results in this paper can provide some reference for the prospecting work in this area.
