摘　　要：铂族元素(PGE)为中国急缺的矿产资源。近年来,国外(如俄罗斯)在黑色岩系内发现了非传统类型的PGE矿床,中国南方也发现了与黑色岩系有关的PGE矿化。黑色岩系将成为PGE和稀有金属的一种新来源。内蒙古中西部狼山—渣尔泰山地区属中元古代裂谷系,具有类似的区域成矿构造背景,黑色岩系极为发育,并在黑色岩系分布区发现有砂铂矿床、PGE重砂异常及一系列与黑色岩系有关的金铜多金属矿床等良好的找矿线索,具有寻找与黑色岩系有关的PGE矿床的找矿前景。In recent years,platinum-group element (PGE)deposits hosted in black shales,a non-tradi-tional type of PGE deposit,have been explored for in some countries,such as Russia.PGE mineralization associated with black shales is also found in southern China.Black shales will become a new resource of PGE and rare metals.There is a similar metallogenic-tectonic setting in the Langshan-Zha'ertaishan area,west-central Inner Mongolia,which belongs to a Mesoproterozoic rift system.In this area black shales are very well developed and placer platinum deposits,placer PGE anomalies and a number of good clues to gold-copper-polymetallic deposits related to black shales have been found in areas where black shales are distributed.So the area has good ore prospects for PGE deposits related to black shales.
