青海赛什塘铜矿区深部找矿前景浅析

Prospective of copper deposit deep exploration in Saishitang Mining Area,Qinghai Province

赛什塘铜矿目前保有资源储量保证程度已达中度危机,通过分析矿区成矿地质条件和矿床特征,发现铜矿体主要分布在大理岩、变质粉砂岩与岩体的接触带上,矿体在走向和倾向上均有向深部延伸的趋势,且矿体在垂向上具有多层分布的特点。深部已施工的见矿钻孔和地质资料分析结果对应,反映矿区深部找矿前景良好。

The retain reserves has reached moderate crisis for further mining in Saishitang Copper Deposit. Based on data of geological characteristics and metallogenetic factors, it revealed that copper orehodies mainly occurred in the contact zone between intrusion and marble or metamorphic siltstoae. And features of spatial distribu- tion of the orebodies display not only a tendency to extend along the strike and dip, but also multi-layer distributed in the vertical variation. Combined with the deep drilling data, it＇s suggested that there is a good potential in deep exploration of Saishitang Copper Deposit.
