豫西卢氏县杨树沟锰矿找矿潜力分析

An Analysis of the Prospecting Potential of Yangshugou Manganese Deposit in Lushi County,Western Henan Province

豫西卢氏县杨树沟锰矿位于华北板块南缘秦岭褶皱系中,矿体严格受二云石英片岩岩层控制,总体属沉积变质型贫锰矿石。分析认为矿区具备多金属矿床综合勘查的潜力,采用EH4连续电导率剖面探测并圈定了找矿靶区,露头揭露发现F2断裂局部赋存金、铅矿体,Au品位1.88 g/t、Pb品位4.10%,证实了矿区具备多金属矿综合勘查的潜力。

Yangshugou manganese deposit in Lushi County is located in Qinling fold system on the southern margin of the north China plate.The ore-body is strictly controlled by the two-dolomite schist strata and generally belongs to sedimentary metamorphic poor manganese ore.The analysis shows that the mining area has the potential for comprehensive exploration of polymetallic deposits,and the prospecting target is detected and delineated by EH4 continuous conductivity profile.The outcrop revealed that F2 fault locally hosted gold and lead ore-bodies,the Au grade 1.88 g/t and Pb grade 4.10%,which confirms that the mining area has the potential for comprehensive exploration of polymetallic deposits.
