摘要
马地金矿位于中秦岭陆缘盆地华力西造山带北亚带,属临潭~徽县铅-锌-铜(铁)-金(银)-钼-锑-汞成矿亚带~温家沟-马泉金-银矿集区,具有良好的成矿地质条件和找矿潜力。本文通过对马地金矿区的地质特征、矿体特征的总结及控矿因素的分析,认为马地金矿床产于特定的构造内和岩性层位,并与围岩蚀变及岩浆活动紧密相关,被控于特定的地质构造背景,有利的成矿地质条件控制了马地金矿的形成,金矿成因属岩浆热液型,以期对在中秦岭陆缘盆地和礼(县)~岷(县)金成矿带内寻找同类型的金矿有所帮助。
Mati gold deposit is located in the north sub-zone of Hualixi orogenic belt in the continental margin basin of the Central Qinling Mountains.It belongs to lintan-Huixian pb-Zn-Cu(Fe)-Au(Ag)-Mo-Sb-Hg metallogenic sub-zone to Wenjiagou-Maquan au-Ag ore concentration area,which has good metallogenic geological conditions and prospecting potential.This article through to the geological characteristics of gold mine area,the summary of the features of ore bodies and the ore-controlling factors analysis,thought the horse to within the structure of the gold deposits originated from a particular strata and lithology,and closely related to alteration of surrounding rock and magma activity,accused in the particular geological structure background,favourable metallogenic geological conditions to control the horse to the formation of gold mine,belong to magmatic hydrothermal type gold deposit formation,In order to find the same type of gold deposits in the continental margin basin of the Middle Qinling and in the Lixian-Min gold metallogenic belt.
