内蒙古林西县北三段银铅多金属矿床成因与成矿模式

Genesis and metallogenic model of silver lead polymetallic deposit in the North section 3,Linxi,Inner Mongolia

北三段银铅多金属矿床位于内蒙古自治区赤峰市林西县官地镇,是一个以银为主,并伴生有可综合利用的铅、锌元素的低温热液型矿床。矿区内主要有上二叠统林西组第四段(P3l4)、第五段(P3l5)和第四系(Q4)出露。通过对矿区地质、矿石特征,结合区域演化过程,提出了成矿模式,为该矿床及其外围进一步的找矿工作提供理论依据和参考。

The silver-lead polymetallic deposit is located in guandi town,linxi county,chifeng city,Inner Mongolia autonomous region. It is a silver-dominated deposit accompanied by elements of lead and zinc that can be comprehensively utilized. The deposit type belongs to low temperature hydrothermal deposit. There are mainly the fourth,fifth and quaternary strata of upper Permian linxi formation. Based on geological and ore characteristics of the mining area,combined with regional evolution process,this paper puts forward the prospecting model. It provides theoretical basis and scientific guidance for further prospecting in this deposit and its periphery.
