中国铂族金属矿床找矿方向初探

根据 2 0世纪 90年代铂族金属矿床勘查的新发现 ,提出铂族金属矿床成因分类 ,探讨中国铂族金属找矿方向 ,提出“以绿找铂”、“以黄找铂”和“以黑找铂”的找矿原则 ,即在蛇绿混杂岩或基性—超基性岩分布区寻找基性—超基性岩浆岩型、岩浆热液型铂族金属矿以及与之有关的砂铂矿床 ,在金矿田中寻找伴生铂族金属矿床 ,在黑色页岩分布区寻找黑色页岩型铂族金属矿床。

Direction in prospecting for platinum-group metal deposits in China

Based on the new discoveries in platinum-group metal prospecting in the 1990s, the authors propose a genetic classification of platinum-group metal deposits, discuss the direction of prospecting platinum-group metals in China and advance three platinum-group metal prospecting principles, i.e. look for basic-ultrabasic type and magmatic hydrothermal type platinum-group metal deposits and their related placer platinum deposits in areas of ophiolitic mélange or basic-ultrabasic rocks, look for by-product platinum metals in gold fileds, and look for black shale type platinum-group metal deposits in areas of black shale.
