中文摘要: |
北直河银铅锌多金属矿床位于北京西部山区,矿体主要赋存于蓟县系铁岭组、雾迷山组,受断裂和层间裂隙控制。通过综合研究区域地质、控矿构造、矿床成因、矿床时空演化以及水系沉积物地球化学特征等,发现成矿元素Ag,Pb,Zn地球化学异常与矿体展布基本一致,异常带连续稳定、规模大,是有利的银、铅、锌多金属成矿远景区,且具有较大的找矿潜力。在总结该矿床的矿床特征、地球化学特征的基础上,探讨了矿床的成矿模式。 |
英文摘要: |
Beizhihe Ag-Pb-Zn deposit is located in the west mountainous area of Beijing. Ore bodies occur in Tieling and Wumishan formations of Jixian System and are controlled by fault and inter-formation fissure. Analysis of regional geology, ore-control structure, genesis and tempo-spatial evolution and geochemical characteristics of stream sediments and soil survey show that Ag-Pb-Zn anomaly is coincided with extension of ore bodies. Metallogenic model is built on basis of deposit and geochemical characteristics of the deposit. |
