内蒙古翁牛特旗大新铅锌矿地质特征及找矿标志

Geological characteristics and prospecting mark of Daxin lead-zinc deposit in Wengniute Banner of Inner Mongolia

大新铅锌矿位于内蒙古自治区东部,赤峰市翁牛特旗政府所在地乌丹镇南西。该区域是内蒙古赤峰地区著名的硐子—荷尔勿苏—梧桐花铅锌多金属矿床集中区,区内岩浆活动频繁,褶皱、断裂发育,具有良好的铅锌多金属矿床的成矿条件。文章详细论述了翁牛特旗大新铅锌矿床地质特征,认为矿床成因类型为受构造裂隙控制的中低温热液充填型铅锌矿,并总结了找矿标志,为下一步勘探和采矿提供了依据。

Daxin lead-zinc deposit is located in the southwest of Wudan Town,where is the seat of Wengniute Banner government in Chifeng City,in the east of Inner Mongolia Autonomous Region.It is the famous Dongzi-Horwusu-Wutonghua lead-zinc polymetallic deposit concentration area in Chifeng City,Inner Mongo-lia.There are frequent magmatic activities,folds and faults are developed in the area.It has the good metal-logenic condition for lead-zinc polymetallic deposit.This paper discusses the geological characteristics of the Daxin lead-zinc deposit in Wengniute Banner in detail,and analyzes the ore controlling factor preliminarily.It is considered that the genetic type of the deposit is a middle and low temperature hydrothermal filling lead-zinc deposit controlled by structural fissures,and the prospecting signs and directions are summarized,which provides a basis for further exploration and mining.
