吉尔吉斯斯坦天山成矿带主要金矿类型及区域成矿规律

Major Gold Deposit Type and Regional Metallogenic Regularity on Tianshan Ore-Forming Belt,Kyrgyzstan

吉尔吉斯斯坦境内天山成矿带是整个中亚地区天山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。吉尔吉斯斯坦天山成矿带自新元古代晚期开始到古生代晚期,经历了长期、复杂的地质构造演化过程,造就其特有的成矿地质条件,产出了一系列不同类型、不同规模的金矿床。结合前人研究工作,系统梳理了吉尔吉斯斯坦天山成矿带内已知金矿床类型,通过各矿床类型中典型矿床地质特征总结、矿床成因分析,从控矿因素、主要成矿期、矿床分布等方面总结了吉尔吉斯斯坦天山成矿带金矿区域成矿规律,以期为吉尔吉斯斯坦天山成矿带开展金矿勘查工作提供理论指导;同时也为我国境内新疆天山地区寻找类似的金矿床提供新的思路。

Tianshan metallogenic belt in Kyrgyzstan is a significant component of the whore Central Asia Tianshan ore-forming belt, and also is the key section connecting the Central Asia gold belt at home and a- broad. From Neoproterozoic to Late Paleozoic, Tianshan had gone through a long and complicated geolog- ical and tectonic evolution. Tianshan belt is characterized by special metallogenic geological conditions. Dif- ferent deposit types and deposit scale for gold deposits had been found Tianshan in Kyrgyzstan. This paper systematically collects data of all known gold deposit types and summarizes, based on previous studies, re- gional metallogenetic regularities of Tianshan metallogenic belt in Kyrgyzstan through ore-controlling fac- tors, major ore-forming stages, distribution of ore deposits by the way of typical deposit model and genesis analysis. The paper offers theoretical guidance for the prospecting work of gold deposits of Tianshan met- allogenic belt in Kyrgyzstan and also provides some new ideas for the studies of similar gold deposits in Xinjiang Tianshan, China.
