摘要
成矿带位于北秦岭北部晚元古代-早古生代裂谷带南缘的变质火山岩区,受油房-皇台断裂的次级分支断裂及燕山-印支期的侵入岩体及次火山岩脉的联合控制,成矿地质条件与甘肃白银厂铜-铅-锌矿田相类似,成矿带内地表已发现多条铜-铅-锌矿(化蚀变)体,找矿潜力较大,只要进一步深入开展工作,有望找到与白银厂铜-铅-锌矿田相类似的大型-超大型铜-铅-锌多金属矿床。
The ore belt is located at the southern fringe of the upper proterozoic to early Palaeozoic rift zone, in the metamorphic volcano rock area, within the northern part of the North Qinling Mountain.Mineralization is jointly controlled by second order fractures of Youfang-Huangtai fault and Yanshanian-Yindosinian intrusion rocks and sub-volcanic dyke. The metallogenic condition is similar to that of the Baiyinchang copper, lead and zinc ore field. Several copper, lead and zinc mineralization-alteration zones have been found on the surface in the ore belt which show ore hunting potential and it is expected to find large to super large copper, lead and zinc polymetallic deposit similar to the Baiyinchang copper, lead and zinc ore field through further work.
