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。 Through the study of the Ia orebody in the Shuiyindong gold deposit, the concept of Sbt is proposed. It is found that the REE characteristics of three major gold deposits related to Sbt, such as the mercury cave, Laowanchang and Leopard Cave, are characterized by the light rare earth content being much higher than that of heavy rare earth and faint right dumping, indicating the consistency of the material components. It is concluded that gold mines in southwestern Guizhou are the products of regional metallogenesis, with the mineral originating mainly in the deep areas. The widespread Sbb in the area is the basis for finding hidden blind gold deposits. Through further work, southwestern Guizhou will find more Many blind gold (antimony) deposits.
