| 摘 要： | 探讨了南泉银金矿地球化学异常与成矿的关系，Au,Ag异常为矿致异常，Au具岩浆热液深部来源特点，Ag来源既为岩石同沉积矿化，又有后期岩浆热液外来物质的多次加入，其成矿规模远远大于Au的成矿规模，碳酸盐岩对Au，Ag成矿有选择性，矿床具层控特征，同时归纳出南泉银金矿的地球化学异常特征和找矿标志。

| Abstract: | The research is a preliminary analysis about the relationship betwee geochemical abnormities and mineralization.Au and Ag abnormities are brought by mineralization, the resource of Au is from deep magma, and the resource of Ag is from the mineralization which is formed at the same time with the rock sediment.Moreover, with the repetitious addition of mineralizing materials of subsequent magma, the scale of Ag mineralization is larger than the scale of Au mineralization. Carbonate rocks are selective to Au and Ag mineralization. And the deposit has characteristics of stratum_controlling. The characteristics of geochemical abnormities and the symbols for prospecting in Nanquan gold_silver deposit are concluded. |
