摘要
经过对 4个金矿区带的系统调查研究 ,发现脉状热液金矿由早而晚具有磁黄铁矿 -石英、黄铁矿 -毒砂、黄铁矿 -石英大脉、金 -脉状黄铁矿、金银 -多金属硫化物、金银 -碲化物、黄铁矿 -石英-碳酸盐 7个阶段。矿床之间的差异只是成矿阶段系列发育的完整程度和成矿阶段发育的强度不同。在矿床、矿带和矿田范围内 ,都具有由上而下、由早而晚的金矿化垂向相对分带 ,Au、Cu、Zn、Pb、Ag存在明显的时空变化趋势。
According to the systematic study on the four gold deposits belts, it is discovered that the vein hydrothermal gold deposits experience seven stages: pyrrhotite quartz, pyrite arsenopyrite, pyrite large quartz vein, gold vein pyrite, Au Ag polymetalic sulfide, Au Ag telluride and pyrite quartz carbonate. The differences of the deposits are only the differences on the completion and the intensity of the development of the metallogenic stages. In the range of the deposits, ore belts and orefields, there are vertical respective zoning of the gold mineralization. There are obviously spatial changing trending on Au, Cu, Zn, Pb and Ag.
