摘　　要：吉尔吉斯斯坦境内天山成矿带是整个中亚地区成矿带的重要组成部分,也是连接境内外“中亚金腰带”的核心部位,产出了大量金矿床,库兰德金矿床就是其中之一。矿体受北东向及近东西向矿化蚀变带控制,含黄铁矿化石英脉为直接找矿标志。目前共发现主要金矿体6条,主要赋存明特金组下段,矿体主要受南北奥科托尔克伊断裂控制,矿体最大延长852 m,倾向135°~240°,倾角54°~72°。本矿床属于含金蚀变岩型金矿床。The Tianshan metallogenic belt in Kyrgyzstan is an important part of the metallogenic belt in the whole Central Asia.It is also the core part of the“central Asian gold belt”connecting China and abroad,producing a large number of gold deposits.The Kurland gold deposit is one of them.The ore body is controlled by the NE and near east-west mineralized alteration zone,the presence of pyrite mineralized quartz veins is a direct indicator for mineral exploration.At present,a total of 6 major gold ore bodies have been found,mainly located in the lower section of the Mingtejin Formation,the ore bodies are mainly controlled by the North South Okotorkyi fracture.The maximum extension of the ore body is 852 metres,with a tendency of 135°-240°,and the inclination angle is 54°-72°.This deposit belongs to a gold-bearing altered rock type gold deposit.
