| 摘 要： | 辽宁五龙金矿含金石英脉中石英晶体的塑性变形显微裂隙和熔融现象普遍发育,在无矿石英脉中上述现象则不发育或缺失.气液包体在含金石英脉中数量多.成矿温度阶段性明显,沸腾现象也较发育.而在无矿石英脉中则反之.据包体化学成分推测成矿溶液化学成分属CO2-H2O-Cl-Na-Ca型,而无矿石英脉热液成分为CO2-H2O-F(Cl)-K-Ca(Mg)型,石英中微量元素浓集克拉克值(Ck)及相关系数表明Au、Sb、Bi、W、Ag为本区主要成矿元素.且含金石英脉的Ck值均大于无矿石英脉.热发光曲线在含金石英脉中主要为双峰和多峰型,而无矿石英脉则为单峰型,上述石英标型特征作为五龙金矿床石英脉中找金的重要标志.

| Abstract: | In Wulong gold deposit of Liaoning, the ductile deformation, microcrack and corrosion in quartz crystals is common in gold quartz vein and uncommon or lacking in barren quartz vein. Fluid inclusion is characterized by abundance, clear stages of mineralization temperature and development of ebullition in gold quartz vein and on the contrary in barren quartz vein.The chemical composion of inclusions lead us to infer that the ore fluid is of CO2-H2O-Cl-Na-Ca type and the hydrothermal solution of barren quartz vein is of CO2-H2O-F ( Cl) -K-Ca(Mg) type. Concentration clarke (Ck) of trance elements in quartz and correlation coefficents show that Au.Sb.Bi.W.Ag are major ore-forming elements and the Ck is richer in gold quartz vein than in barren quartz vein. The thermoluminescence curve shows double peaks or multiple peans for gold quartz vein, but single peak for barren quartz vein.
Above typomorphic characteristics of quartz are important indicators for gold quartz veins in the Wulong gold deposit. |
