摘　　要：本文简要介绍了滥木厂汞铊矿床的区域地质背景和矿床地质特征，着重对矿床矿石的物质组成和铊的赋存状态进行了初步研究。铊在矿床中除形成红铊矿和少量其它铊矿物外，大部份以类质同象、离子吸附状态分散存在于各种硫化物矿物中，特别是富砷的胶状黄铁矿是最主要的载铊矿物。矿床内有独立存在的富铊矿体和合矿体，通过实验室实验已获取了一粒绿豆大小的金属铊。这些均为开发利用贵州的铊资源提供了光明前景。In this paper a brief description is given for the regionalgeologic setting. and ore features of the Lanmuchang mercury--thallium depositsituated in Xingren county of southwestern Guizhou and a study is focused on orecomposition and the occurence of thaullium in the ores. We suggest that most ofthallium scatters as isomorph and ion absorption throughout the various sulfideminerals, minor forms lorandite and other thalllium minerals. The colic formarsenic-rich pyrite is the most important thallium-carrying mineral in the studieddeposit.Some thallium-rich individual orebodies and mineralized bodies from which agrain of metal thaullium mineral in the same size closely as mung beau has beenseparated in the laboratory were also found in the mercury-thallium deposit. The study performed will provide the data for producing thallium from the deposit.
