摘要
通过对水银洞金矿床Ⅰa矿体的研究,提出Sbt的概念。研究发现:与Sbt有关的水银洞、老万场、豹子洞3个主要金矿床稀土元素特征,都表现为轻稀土含量大大高于重稀土、微弱右倾型,表明物质组分的一致性。初步得出,黔西南地区金矿是区域成矿作用的产物,矿质主要来源于深部,区内广布的Sbt为隐伏盲金矿床找寻的依据,通过开展深入工作,贵州西南部将会发现更多的盲金(锑)矿床。
Rare-earth elements（REE） of Shuiyindong, Laowanchang and Baozidong gold deposits related to the Sbt show that contents of light REE are much higher than ones of heavy REE and REE curve slants to the right. These may indicate the sane source of metallogenetic elements in these gold deposits. Preliminary researches indicate that gold de- posits of southwestern Guizhou Province in China are products of regional mineralization, the metallogenetic elements are mainly from depth and the Stb in the region is basis for prospecting blind deposits. More gold deposit will be found in southwestern Guizhou, through further studies.
