地球化学分析方法在吉尔吉斯斯坦库姆托尔金矿邻区找矿潜力预测中的应用

摘要

库姆托尔金矿是吉尔吉斯最大的金矿，是中亚著名金矿之一。应用吉尔吉斯斯坦9幅1∶5万化探资料（3万条数据）进行系列地球化学编图和地球化学信息提取，结合在吉尔吉斯天山成矿带成矿规律研究所取得的认识，建立了库姆托尔金矿的地质地球化学模型。在相似类比理论指导下，借助计算机技术对吉尔吉斯斯坦中天山成矿带库姆托尔型金矿的找矿潜力进行科学评价，在吉尔吉斯库姆托尔地区圈定库姆托尔型金矿找矿预测区2个。%The Kumtor gold deposit, one of the most famous gold deposits in Asia, is the largest gold deposit in Kyrgyzstan. In this study, geochemical maps were compiled, and geochemical information was extracted from about 30000 geochemical data obtained from nine sheets at the scale of 1∶50000. On the basis of the results obtained from the Tianshan metallogenic belt in Kyrgyzstan, the geological and geochemical model of the Kumtor gold deposit was built. Guided by similar analogy theory and computer technology, the authors evaluated the resources potential of the Kumtor gold deposit in middle Tianshan belt in Kyrygzstan scientifically and delin⁃eated two prospecting prognostic areas.
