广西富钟贺地区钨锡多金属矿床成矿系列研究

         

摘要

Fu-Zhong-He region is located at the convergence of the fold belt of central-south of Hunan and the fold belt of China and the fold lines of Hunan and Guangxi. The favorable metallogenic conditions resulted in the formation of a variety of different types of tungsten and tin-polymetallic deposits in the region. Tungsten and tin-polymetallic deposits occur mainly in devonian strata in this region. Spacial distribution of the deposits goes from greisen type skarn deposits of the internal granite to skarn type tungsten and tin ore deposit on internal and external contacts and then to the outer zone of the contact or away from the contact with the tin polymetallic sulfide type and quartz vein deposits. Metallogenic epoch is mainly in the middle and late Yans-hanian period, closely associated with Yanshanian granite in ore genesis, forming tungsten and tin polymetallic deposit series in Fu-Zhong-He region.%富钟贺地区位于湘桂褶皱系湘中南褶皱带与华夏褶皱带的交汇处,区内良好的成矿条件形成了各种不同类型的钨锡多金属矿床.钨、锡多金属矿床主要赋存于泥盆纪地层中,在空间上从花岗岩内部的云英岩型—矽卡岩矿床→内外接触带的矽卡岩型钨锡矿床→外接触带或远离接触带的锡多金属硫化物型和钨锡石英脉型矿床;成矿时代主要是在燕山中、晚期,成因上同燕山期花岗岩有着密切联系,共同构成富钟贺地区钨锡多金属矿床成矿系列.
