摘要
通过对湘南芙蓉锡矿田地质特征的研究 ,认为芙蓉锡矿田与东坡和香花岭两大锡多金属矿田具有相同的成矿特征和相同的成矿时代 ,所不同的是芙蓉锡矿田的矿体主要位于大岩基中 ,其矿体的展布和矿脉 (体 )的形态及其产状等严格受断裂构造控制。铅同位素组成显示其成矿以壳源物质为主 。
Furong tin orefield, situated in the near central part of seven big orefield in Hunan Province, is a large-typed tin orefield recently discovered.The study of the geological characteristics of this orefield reveals that Furong orefield shares the smilasity with two other orefields,Xianghualing and Dongpo,in mineralization and age.They are different in that the orebody in the Furong orefield is mainly located in the large basement with the extension and distribution greatly controlled by faults.While the tin isotope constitution displays that the mineralization is dominated by materials from the crust and the multi-metal tin mineralization is related to the introsion of the fined-grained granites in the later stage of early Yanshanian.
