凡口大型层控铅锌矿床位于广东省北部,中上泥盆纪湘、桂、粤海盆的东部边缘。产于加里东运动后中上泥盆系近底部的碳酸盐岩中。有关它的成因曾提出过礁控成矿、成岩改造及火山成矿等见解。笔者两年来做了较多研究工作,本文将对地质特征和矿床成因于以讨论。 The Fankou large-scale stratabound lead-zinc deposit is located on the eastern edge of the middle and upper Devonian Hunan, Guangxi and Guangdong basins in northern Guangdong. Produced in the Caledonian movement in the Upper Devonian carbonate near the bottom of the carbonate. Concerns about its origin have been proposed reef control mineralization, diagenetic alteration and volcanic mineralization and other insights. The author has done more research work in the past two years. This paper will discuss geological features and ore deposits.
