摘要
分散元素Te、Se、Cd、Tl在某些类型金矿中可以富集,是黄金找矿的重要指示元素,甚至是最重要的指示元素。Te、Se主要富集在与碱性岩浆活动有关的金矿中,Cd主要富集在火山热液型金矿和古老结晶基底内的糜棱岩型金矿中,而Tl则在卡林型金矿中富集。分散元素在金矿床中的地球化学信息丰富了黄金找矿方法理论,拓宽了找矿思路。
Geochemistry research results in some gold deposits show that dispersed elements like Te, Se, Cd, and Tl may be enriched in some types gold deposits. They arc important indicator elements, sometimes even the most important indicator element. Te and Se are enriched in those deposits which relate with alkali - magma activities. Cd in those deposits which occur in crystalline basement mylonite, and Tl in Carlin - type gold deposits. The dispersed elements give some geochemistry information for prospecting of gold deposits, which should be paid attention.
