摘　　要：对全球主要铊矿床的成矿地质背景、成矿时代、控矿构造、赋矿围岩和成矿物理化学条件进行了综合对比分析,得出了全球铊矿床的分布特征与成矿规律:铊矿床主要产出于沉积岩发育的中—低温成矿域中,且成矿时代较新;铊矿床的赋矿围岩通常为铊背景值高的沉积岩;大多数铊矿床具有典型的低温成矿特征。This paper clarifies the distribution characteristics and metallogenic regularities of thallium deposits through a classified and synthetical study of some features, including geological background of ore-formation, metallogenetic epoch, ore-controlling structures, wall-rocks and physicochemical conditions of the thallium deposits in the world.It concludes that most of thallium deposits are located in the low to moderate temperature metallogenic provinces and the deposits are young; the wall-rocks of thallium deposits are mainly sedimentary rocks with high thallium background content; and that thallium deposits have characteristics of epithermal mineralization.
