青海省牛苦头铁矿区滩间山群火山沉积岩中层状富铅锌矿体的发现及其地质意义

The Discovery and Geological Significance of Rich Lead-Zinc Orebody in the Volcanic Sedimentary Rocks of Tanjianshan Group in Niukutou Mining Area, Qinghai Province

通过详细的野外地质填图及室内岩相学研究,初步确定牛苦头矿区M2磁异常区出露地层为早古生界奥陶系滩间山群,布设钻孔首次在滩间山群火山沉积岩中揭露到层状富铅锌矿体,证明该区滩间山群中具有寻找厚大的富铅锌矿体的潜力。

Through detailed field geological mapping and petrography study, it’s preliminarily determined that the outcropping layer of M2 magnetic anomaly area in the Niukutou mining area is Tanjianshan Group. Through the drilling, it found layered rich lead-zinc orebody in the volcanic sedimentary rocks of Tanjianshan group. The research proves that it has the potential to find thick and rich lead-zinc ore bodies.
