摘要
紫金山大型铜(金)矿床是我国大陆发现的首例高硫浅成低温热液型(石英—明矾石型)矿床。随着勘探工作的深入,在该矿床深部及边部相继发现了斑岩型铜(钼)矿、中低温热液型铜金矿和低硫浅成低温热液型(绢云母—冰长石型)银、金、铜矿。各类型矿床间的浅成热液系统连续过渡,这在世界上是具代表性的矿例。不仅具有重要的找矿意义;而且在陆相火山成矿方面有重要理论意义。
Zijinshan large-scale copper gold deposit is regarded as the first high-sulfur epithermal(quartz-alunite) deposit discovered in the Chinese continent. With the further geologic investigation, porphyry copper(molyhdenum)deposits and mesothermal copper gold deposits as well aslow-sulful epithermal (sericite-adularia) silver gold copper deposits have been found one byone in the deep and around Zijinshan deposit. The successive transition 0f epithertnal systemfrom one type to another is considered as the example, which show significance both in metal-logenic theory and ore hunting practice.
