摘要
通过对贵州兴仁滥本厂汞矿区的实地考查和一系列室内研究工作,发现了自然界极为罕见的红铊矿,并进而肯定了该矿区汞铊共生矿床中有富铊矿体的存在。红铊矿和富铊矿体在我国均属首次发现。根据元素地球化学、矿物包裹体和硫同位素资料,结合矿床的地质特征,从矿源层的形成环境、红铊矿和富铊矿体产出条件、汞铊等成矿元素的活化迁移及其沉淀机制等方面,对矿床的地球化学特征和矿床成因进行了初步讨论,取得了可喜的成果。
Through geological investigation of Lanmuchang mercury ore area Xingren, Guizhou, a series of experiments and analysis being made, the writer discovered Loradite, a rare mineral which grows in the rich-thallium ore body. Based on the data from elemental geochemistry, mineral inclusion and sulphur isotope, concerned with the geological characteristics of ore deposit, a discussion was made about the mineralization mechanism of the ore deposit in terms of the surroundings in which the ore deposit was formed, the occurrence condition of Lorandite and rich-T1 ore body activation, remove and deposition of mineral-forming elements-Hg, T1,As etc.
