通过河北石湖金矿野外产出的地质现象及矿脉间的穿插关系,结合显微镜和电子探针进行综合分析。本矿区主要为两个矿化阶段,即石英-黄铁矿阶段和石英-多金属硫化物阶段:石英-黄铁矿阶段主要产出矿物:石英、黄铁矿、银金矿和金银矿等;石英-多金属硫化物阶段主要产出矿物:石英、黄铁矿、闪锌矿、方铅矿、黄铜矿、银金矿、金银矿、硫碲银矿、辉银矿和自然银等。本文着重对这两个阶段产出的含Au、Ag矿物特征进行了探讨性研究。其中两个矿化阶段中都产出银金矿与金银矿,随着温度的下降Au的含量呈下降趋势Ag含量呈上升趋势,Au与Ag呈负相关性,类质同象替代。本区产出的硫碲银矿是前人研究中未见有报道的矿物,产出于晚期多金属脉中并与闪锌矿、黄铁矿和黄铜矿共生。Ag含量与Te含量成弱负相关性。
Through the geological phenomenon of the output of Hebei Shiju goldfield and the interlacing relationship between the veins, a comprehensive analysis was made with the combination of microscope and electron probe. The mining area is dominated by two mineralization stages, quartz-pyrite stage and quartz-polymetallic sulphide stage: Quartz-pyrite stage Main outputs Mineral: quartz, pyrite, silver-gold mine and gold-silver mine Etc. Quartz-polymetallic sulphides Main outputs: Quartz, pyrite, sphalerite, galena, chalcopyrite, silver and gold ores, gold and silver ores, sulfur and silver silver ores, silver ores and nature Silver and so on. This paper focuses on the characteristics of Au, Ag minerals produced in these two stages. Silver and gold mines and gold and silver mines were produced in two mineralization stages. The content of Au decreased with the decrease of temperature, while the content of Ag increased with the decrease of temperature. Au and Ag were negatively correlated and the isomorphism replaced. Sulfur telluride silver ore produced in this area is not reported in the previous study of minerals, produced in the late polymetallic pulse and with sphalerite, pyrite and chalcopyrite symbiosis. Ag content and Te content into a weak negative correlation.
