内蒙古白音敖老铅银多金属矿床地质特征

Geological characteristics of Baiyin Aolao PB-Ag polymetallic deposit in Inner Mongolia

通过对白音敖老铅银多金属矿的地层特征、物探、化探异常的研究发现,该矿区内构造断裂发育,围岩蚀变普遍,热液蚀变岩型铅银多金属矿化,成矿时代为燕山期。本矿床具备很好的成矿地质与地球化学条件,具有很好的找矿前景,应通过进一步系统的地表矿体揭露和深部验证工作,以期寻找到铅锌银多金属矿床。

Based on the study of the stratigraphic characteristics,geophysical and geochemical anomalies of the Old Lead-Silver polymetallic ore deposit in Baiyinao,it is found that the tectonic fault is developed,the wall rock alteration is common,the hydrothermal alteration rock type lead-silver polymetallic mineralization,and the mineralization period is yanshan period.This deposit has good ore-forming geological and geochemical conditions,and has a good prospect for ore prospecting.Further systematic surface orebody exposure and deep verification should be carried out in order to find the pB-Zn-AG polymetallic deposit.
