通过对矿体围岩花岗闪长岩、花岗斑岩类和隐爆角砾岩筒控矿_容矿构造及矿石组分的研究 ,将金厂矿床金矿化类型分为破碎蚀变岩型、裂隙充填型和角砾岩型 ;对矿物学和同位素地球化学的研究结果表明 ,成矿物质主要来源于深部 (岩浆源 ) ,在成矿作用早期阶段成矿流体主要为岩浆水 ,晚期阶段有部分大气水的加入。金厂金矿床是中生代火山_次火山活动的产物 ,矿床属浅成低温岩浆期后热液型金矿床。
Based on the research on ore-controlling structure and ore components of granite diorite, granite porphyry and cryptoexplosive breccia in ore body, the gold mineralization types of gold deposit are classified into crushing alteration Rock type, fissure-filling type and breccia type. The results of mineralogical and isotopic geochemistry show that the metallogenic materials mainly come from the deep (magmatic source), and the ore-forming fluid is mainly magmatic water in the early stage of metallogenesis, Late stage of some atmospheric water to join. The Jinchang gold deposit is a product of the Mesozoic volcanic-subvolcanic activity. The deposit belongs to the epithermal-type gold deposit after the epithermal magmatic epoch.
