摘要
本文从铊的单矿物，矿物中的铊，岩矿石中的铊和铊元素组合四个方面进行讨论。根据铊存在形式及其与有关元素密切程度不同，将金、汞、砷、锑矿床中元素分为三组即相关元素，共生元素和伴生元素。在此基础上提出找矿前提。
In this paper the authors discussed in more detail thallium from following four aspects: its monomineral,content of thallium in main mineral, content of thallium in rock and ore, and the element association in connection with other element. Elements of gold, mercury, arsenic and antimony ore deposits can be grouped into three groups according to the existent form of thallium and the close degree in thallium with other element, ie. ,correlative, paragenitic and associated element. On the basis of geochemical study of ore deposits and their mineralizing mechanism, some prerequisites for prospecting these deposits have been proposed, fore xample, content of thallium in rock and ore,>10ppm, 5-10ppm, 1-5ppm, are exploration mark for the ore deposit, the mining area, and the mineral belt of gold, mercury,arsenic and antimony respectively. Hutchinonite (PbT1As5S9) and picotpaulite(T1Fe2S3) has been found by author recently from Nanhua arsenic deposit, Yunnan province, China.
