摘要
根据对拉拉铜矿床的矿石结构、构造及矿物共生组合的研究,发现矿石中含有大量自然金和含铂族元素的碲化物。自然金的赋存状态为包裹休金、粒间金、裂隙金。主要的载金矿物有黄铜矿、黄铁矿、叶碲铋矿,含金性最好的岩石类型为只云母钠长片岩。金与成矿元素铜的关系最为密切。
After study of the relatuons of the structure,texture and associated minerals a great number of natural gold and telluride are discovered in the ore. Occurrence of natural gold in the ore is observed included-gold,embedded-gold and fissure-filled gold.The main gold-carrying minerals are pyrite,chalcopyrite and telluride. The best gold-carrying rock is the biotite-albit schist.Gold has a cIose relation with element copper.
