摘要
银洞山铅锌矿床位于豫西南马市坪铅锌银矿集区,地处栾川—维摩寺断裂带南侧,矿体赋存于栾川群煤窑沟组,区内岩浆活动频繁,构造作用复杂,为成矿有利的地段。通过对其矿床地质特征、微量-稀土元素蛛网图、硫同位素、铅同位素地球化学特征进行分析,认为该矿床成因是与岩浆岩作用有关的岩浆热液型矿床。
Yindongshan Pb-Zn deposit is located in the Mashiping Pb-Zn-Ag ore-assembly-district,southwest Henan Provinc,in the south side of the Luanchuan-Weimaosi fault zone.The orebodies occur in the Meiyaogou Formation of Luanchuan Group.Through a study on the geological characteristics,geochemical characteristics,S-isotopes and Pb-isotopes of the deposit,it is concluded that the deposit belong to magmati-hydrothermal type deposit associated with magmatic action.
