摘　　要：中酸性岩体中Ｋ、Ｎａ的含量互为消长．在斑岩铜矿岩体中，Ｋ可指示岩体的含矿性，Ｎａ可以指示岩体蚀变及矿化范围．矽卡岩铁铜矿床的生成，则往往伴有Ｎａ化．因而地球化学找矿可以利用Ｋ、Ｎａ作为寻找。During the practice of prospecting for the ore, the content of K in the intermedicate acid rock bodies is rich while Na is poor, or the otherwise. In the rock bodies of bornitr, the ore bearing nature of the rock bodies can be indicated by K, the altered and mineralized limits can be delimited by Na. In the iron copper mineral deposits of the skarn, strong sodication is often existense.
