内蒙古中部召河庙地区金矿成矿规律及找矿预测

总结了召河庙地区金矿的成矿规律，指出本区所发现的具一定规模的金矿（化）点在区域上主要集 分布于青灰窑子－大井－程二沟－东柜一线，矿体均为含金石英脉。容矿岩系为新太古代变质石英闪长岩、斜长岩花岗岩。成矿物质来源主要为古老的变质中基性深成侵入岩，即所谓广义的绿岩带。矿源岩中金物质的活化受深断裂作用、韧性剪切作用、退变质作用、变质流体以及岩浆热液的多重影响，其中以构造作用和岩浆热液最为重要。金矿的形成时期较长，主成矿时期在元古代。预测程二沟－白音查干－东柜一带为今后进一步寻找金矿的优选靶区。

Metallogenic regularity and prognosis of gold deposits in Zhaohemiao area, Inner Mongolia

Metallogenic regularity of gold deposits is summarized, and it is pointed out that gold deposits mainly distribute in Qinghuiyaozi-Dajing-Chengergou-Donggui belt of Zhaohemiao area. All orebodies are gold quartz vein type and hosted in New Archaean metamorphic quartz diorite and plagiogranite. The gold might come from metamorphic basic-intermediate plutons or greenstone belt. Deepseated faulting, shearing, retrograde metamorphism and magmatic hydrothermal fluid resulted in activation of gold in source rock in which tectonic process and magmatic hydrothermal fluid were the most important metallogenetic factors. Gold mineralization endured a long process,but the Proterozoic mineralization is the most important. Geological data show that the Chengergou-Baiyinchaagan-Donggui area might be the other favorable gold-mineralized area in the studied region.
