摘　　要：贵州兴仁滥木厂汞、铊矿床,矿体主要产出于上二叠龙潭组和长兴组泥岩、灰岩、泥质灰岩、硅质岩、煤岩和碳质页岩等混杂岩系。利用扫描电子显微镜及能谱分析等研究手段,对该矿床的物质组成、矿物成分特征及微观特征进行了探讨,为成矿元素汞、铊的赋存状态,生物成矿特征研究等提供矿物学资料。In the Lanmuchang Hg-Tl deposit, Xingren, Guizhou the orebodies occur mainly in the Upper Permian Longtan Formation and Changxing Formation mudstones, limestones, argillaceous limestones, siliceous rocks, coal seams and carbonaceous shales. In this study scanning electron microscopy and energy dispersive spectrometry were employed to study the eomposition of ore-forming material, mineral compositional characteristics and micro features of the deposit, thus providing valuable information about the occurrence modes of the ore-forming element Hg and Tl and the basis for the study of bio-metallogenic characteristics.
