摘要:

吉尔吉斯斯坦布丘克金矿区萨济托尔金矿床为岩浆热液蚀变岩型金矿床,其围岩蚀变种类多、组合复杂。为进一步研究其成矿富集规律,提供找矿线索,在对萨济托尔矿段围岩蚀变类型研究的基础上,总结了围岩蚀变分带规律,并对围岩蚀变与金矿化的关系进行了讨论。结果表明:硅化、钾化和黄铁矿化与金矿化关系密切,而绢云母化和绿泥石化对金的富集成矿也起着重要作用;围岩蚀变带自矿体(化)向外由黄铁矿化-硅化-钾化带向外过渡为黄铁矿化-硅化-绿泥石化带,最外侧为绿泥石化-碳酸盐化带;围岩蚀变组合复杂、种类多的地段,往往矿化好,可以形成矿(化)体。

Abstract:

Sazitor Gold Deposit located on Buchuk Gold Ore Belt in Kyrgyzstan is an magmatic hydrothermal fluid altered rock type gold deposit.The wall alteration types are various and in complicated combination.For further understanding of the ore-forming and enrichment rules and prospecting indications,the paper summarized the zonation rules of wall rock alteration and discussed the relation between wall rock alteration and gold mineralization based on the study of wall rock alteration type in Sazitor Ore Section.The results show that silicification,potassic alteration and pyritization are closely related to gold mineralization while sericitization and chloritization also play important roles in the gold enrichment; From the ore (mineralization)bodies in out,wall rock alteration transits from pyritization-silicification-potassic zone to pyritization-silicification-chloritization zone,and outermost is the chloritization-carbonatization zone; the spot where the wall rock alteration combination is complicated and the types are various usually bears good mineralization and is likely to form ore(mineralization) bodies.
