摘要
滩间山金矿产于柴北缘成矿带中,是一个由岩性控制产出层位、构造控制产出形态的金矿床。矿区内产出有炭质糜棱片岩型矿石和岩脉型矿石2种矿石类型,并且这2种矿石类型是在2个不同的成矿期内形成的。通过对矿区内的主要构造分析研究认为,华力西期形成的近南北向褶皱控制了主要矿体的产出规律。
The Tanjianshan gold deposit is located in the northern margin of the Qaidam basin, whose orebody horizons are controlled by lithology, and orebody shapes are tcctonically controlled. Two types of ores were developed in the deposit, i.e., the carbonaceous mylonite ores and dyke type ores, and they were formed in two different mineralization periods. Through analysis of the main structures within the deposit, it is inferred that the Variscan nearly NS-trending folds control the occurrence regularity of the main orebodies.
