摘要
本文研究了元岭金矿含金单矿物黄铁矿和方铅矿的一般特点和微量元素及其变化规律，并发现：黄铁矿和方铝矿微量元素含量由早至晚的变化显示出亲石元素→亲石铁族元素→亲硫铁族元素→高温亲硫元素→低温亲硫元素逐次富集的过程，这与围岩蚀变和成矿溶液的变化惊人地相似，热液演化在岩石和矿物中的表现一致。
Through Studied on the ordinary characteristics,trace elements and their regular changing Pattern of gold-bearing minerals-pyrite and galena in Yuanlin gold deposit. It has been found that the Change of trace elements in pyrite and galena from early to fate is showing the enrichment process from lithophile elements→lithophile iron group elements→sulfophile iron group elements→hypothermal sulfophile elements→low temperature sulfophile elements in turn. This sequence is marvelously similar to the change of wall-rock alteration and ore-forming solution.The behavior of hydrothermal evolution is same in rocks as in minerals.The enrichment of gold occures in the transitional stage between iron group elements metasomatism and sulfophile elements metasomatism, or in the early stage of sulfophile elements metasomatism.
