摘要

通过归纳丹玉金铜多金属矿的成矿期次,为该矿床的下一步找矿工作提供依据。本文结合区域成矿背景,分析了矿区地质特征,归纳总结了该矿床的成矿规律。研究表明:①金铜多金属矿主要产于石炭系托库孜达坂组的大理岩-片岩中;②矿化蚀变以褐铁矿化、绿泥石化、硅化、黄铁矿化、绢云母化为特征;③丹玉金铜多金属矿分为沉积变质期、热液成矿期和表生期三个成矿期,矽卡岩、氧化物、硫化物及碳酸盐四个成矿阶段。
        By summarizing the metallogenic stages of Danyu gold-copper polymetallic deposit, this paper provides the basis for the next prospecting work of the deposit. Based on the regional metallogenic background, this paper analyzes the geological characteristics of the ore area, and summarizes the metallogenic regularity of the deposit. The results show that:(1) the gold-copper polymetallic ore mainly occurs in limestone and shale of the Tokuz Daban formation of Carboniferous;(2) the mineralization alteration include limonitization, chloritization, silicification, pyritized and sericitization;;(2)Danyu gold-copper polymetallic deposit is divided into three metallogenic stages: sedimentary metamorphic period, hydrothermal metallogenic stage and epigenetic stage;and skarn, oxide, sulfide and carbonate metallogenic stages.
