摘要:
从不同标高、不同矿化带的流体包裹体研究入手,系统地论述了七宝山铜多金属矿床成矿流体 的性质、演化过程及其与成矿的关系。黄铁矿爆裂测温表明:成矿流体温度变化在平面上以岩体为中心 向四周依次为291℃～287℃～279℃,在剖面上由下往上依次为312℃～286℃～228℃。成矿流体 成分主要为H2O,其次为CO2,H+浓度由早期到后期呈递减趋势,表明成矿热液由酸性—弱碱性演化, 同时反映了矿床由高温到中低温的形成过程。
Abstract:
Based on measures of fluid inclusion in different levels and mineralized belt, the characteristics and evolution process of ore-forming fluids in the Qibaoshan Cu-polymetal deposit are discussed systematically. Decrepitation thermomer of pyrite shows temperature of the ore-forming fluids dropped slowly from 291℃ to 279℃ around the rock body in horizontal, and varied from 312℃ to 228℃ from the lower level upward in profile. The main composition of the fluids was H2O and CO2, the concentrations of H+ decrease during evolution of the ore-forming fluids, showing tendency of the fluids from acidity to alkalescence and process of ore-forming.
