摘要
小宛南山金矿集中区包括2个矿床和3个矿点,矿石类型有4种:石英脉型,蚀变糜棱片岩型,钠长石岩型,次生石英岩型。矿化规模大,品位较低。金矿化集中区受中晚元古代绿岩带控制,金矿床、矿点的定位受绿岩带中火山岩机构及次火岩体控制,含金矿化带的定位受次火山岩岩体周围的韧性剪切带控制,韧性剪切带中的脆性构造控制金矿体。根据上述控矿规律,选出2个成矿远景预测区。
There are two gold deposits and three gold mine areas in the Xiaowannanshan gold deposit, which has two characteristics of larger mineralization and lower quality. There are four mainly types of gold deposit, quartz vein type, slacking alteration rock-quartz vein type, albitite type and secondary quartz. The mine mineralization is controlled by the Greenstone Belt of the Middle Proterozoic Period. The exact location of gold deposits and gold mine areas is controlled by Volcanic and Subvolcanic Rock Body. The gold deposit is controlled by brittle structure of ductile shear zones. Two gold deposits was chosen.
