嘎拉勒矽卡岩型铜金矿是继多不杂、尕尔穷等大中型铜多金属矿床后,在班公湖-怒江成矿带西段发现的又一中型矿床。作者通过镜下对光片、薄片进行鉴定的基础上结合扫描电镜和X射线能谱成分分析,对矿石矿物特征及赋存状态做了系统的鉴定和研究。矿石中除常见金属氧化物、金属硫化物外,还发现了自然金、自然银、辉银矿等贵金属矿物;辉铋矿、自然铋、辉锑矿等重要铋、锑的工业矿物;自然铁、自然铜及金属互化物,发现罕见的含放射性元素(Tc、Pa、U、Th)的自然银。并通过对Ag与Pb、Pa、U相关性分析显示出共生关系密切。研究表明嘎拉勒矿床是成矿物质成分复杂的矽卡岩型铜金矿床,矿石综合利用潜力巨大。
The Galallar skarn-type copper-gold deposit is another medium-sized deposit discovered in the western section of the Bangong Lake-Nujiang metallogenic belt after the large-scale copper-polymetallic deposits such as Duomozaogu and Gaerliao. The author systematically identified and studied the characteristics and occurrence state of ores by means of microscopic examination of light films and flakes, combined with the scanning electron microscopy and X-ray energy spectrum analysis. In addition to the common metal oxides and metal sulfides, the ore also found precious metal minerals such as natural gold, natural silver and glittery silver, industrial minerals such as bismuth and natural antimony bismuth, natural bismuth and stibnite, natural iron , Natural copper and intermetallics, found rare natural radioactive elements (Tc, Pa, U, Th) of natural silver. And through the correlation analysis of Ag with Pb, Pa, U showed symbiotic relationship. The study shows that the Galalé deposit is a skarn-type Cu-Au deposit with complex composition of ore-forming materials, and the comprehensive utilization of ore has great potential.
