| 摘 要： | 铜石金矿田是新发现的新类型金矿田,该矿田金矿化类型较多,隐爆角砾岩型金矿化是最主要的类型.但以往常用的某些化探指示元素在大型金矿床附近也只有孤立的Au、Ag元素异常;而在不具有工业价值的斑岩型、夕卡岩型金矿点附近形成了高浓度的多元素组合异常.以前常用的化探指示元素已经不能满足该区野外找矿的需要.为了强化矿致异常,弱化非矿异常,该矿田外围找矿应利用分散元素Te、Se和卤素元素F的指示作用.

| Abstract: | Tongshi is a new type of ore field discovered recently with multi-mineralization types recognized. Crypto-explosion breccia Au mineralization is the major one. Indicator elements used in other ore field show only Au, Ag anomly in large Au deposit. Whereas high concentration and multi-element combination occur at uneconomic porphyry and skarn Au ore accurrances. Therefore, the indicator elements formerly used can not meet needs of ore search in the area. The disperse elements such as Te,Se and halogen element F should be fully made use of for indication and strengthening the ore-caused anomly and wcakening the non-ore anomly. |
