摘要
敖包山铅锌矿区位于华北陆块北缘 ,少郎河多金属成矿带的东段 ,已发现有敖包山、大孤山、双山子等三处矿床。敖包山矿床矿脉呈对称状分布于敖包山倒转背斜两翼 ,志留系下统水泉沟组为主要含矿地层 ,矿脉均受石英绿片岩、绿片岩控制。为“沉积 -变质 -热 (气 )液改造型”矿床。矿床向 NE方向应有相当长度的延伸 ,矿区进一步找矿方向应是
Aobaoshan lead zinc ore field is located in the north margin of north China continent and eastern part of Shaolangshan polymetallic ore zone. There are three known ore deposits such as Aobaoshan, Dagushan and Shuanshanzi deposit. Aobaoshan deposit is symmetrically distributed on both wings of Aobaoshan reversed anticline with Shuiquanguo formation of Lower Silurian as main ore bearing stratum. The ore veins are controlled by quartz greenschist and greenschist rock. The ores belongs to 'sedimentation metmorphism hydrothermal (gas) reformation' type deposit. It should extend further northeastward in a long distance and the further prospecting target should be the anomaly area of D3 polorization ratio.
