摘要
青岗坪金矿矿体的产状、形态受层状滑脱蚀变破碎带的控制,且与太华群与熊耳群主拆离带近平行产出,呈近东西向展布。矿区内矿石自然类型可分为强硅化蚀变岩型金矿石和绢云绿泥蚀变岩型金矿石,金品位的变化与硅化、黄铁矿化、方铅矿化关系密切,矿体厚度与硅化、黄铁矿化、方铅矿化蚀变范围有关,蚀变越强,矿体厚度越大。
The attitude and shape of the Qinggangping gold ore body are tightly controlled by layered decollement crushed zone,which is near parallel with main detachment zone of the Taihua Group and Xionger Group, showing nearly eastwestern distribution. The natural types of ores in ore district can be divided into chloritization and sericitization of altereds type gold ore. The changes of the gold grade is closely related to silicification, pyritization and galena. And the thickness of orebody is related to the range of alteration of the silicification, pyritization and galena. The stronger the alternation, the thicker ore body will be.
