甘肃省肃北县狼查沟金矿床找矿方法及成矿潜力分析

Prospecting method and metallogenic potentiality analysis of Langchagou gold deposit in Subei County of Gansu Province

甘肃省肃北县狼查沟金矿位于加里东褶皱带南祁连区,矿体赋存于中奥陶统盐池湾组凝灰岩、凝灰质砂岩中,受NEE向断裂构造控制,志留纪闪长岩为金矿化提供了热源,也提供了部分矿质。通过对狼查沟金矿床钻孔原生晕及控矿因素的研究,认为矿区深部具有较好找矿前景。

The Langchagou gold deposit is located at the South Qilian area of Caledonian fold belt in Subei County of Gansu Province. The orebody is hosted in tuff and tuffaceous sandstone of the Yanchiwan Group of middle Ordovician system, which is controlled by NEE fracture structure. Silurian diorite provides the heat source for gold mineralization, and also provides some minerals. According to the study of borehole primary halo and controlling factors of Langchagou gold deposit, it is considered that there is a great prospecting potential in the deep part of the deposit.
