| 摘 要： | 利用黄铁矿进行找金是一种新的地球化学找矿方法。其特点是黄铁矿在矿化作用的早期对金及其伞生元素的富集，使金矿外围散染状黄铁矿中出现的金的异常；在金的成矿时期，由于自然金的形成，黄铁矿中金的含量下降。

| Abstract: | It's a new-geochemical method,which gold deposits are surveyed with pyrites.As accumulating gold and associatedposits in prime of mineralization.Concentration of gold and associated elements decreased in the pyrites,which distributedin the ore body,bcause natural golds and massive pyrites were produced in the metallogenic period.We utilized the change of concentration ratio between pyrites and rocks to survey gold deposits. |
