南岭成矿带位于欧亚大陆东南端,东邻太平洋板块,西与印度板块相接,处于滨太平洋构造域与特提斯构造域的交汇部位,横跨扬子和华夏两大板块。该成矿带以发育大量花岗岩,盛产有色、稀有金属而闻名于世(付建明等,2011)。其中,钨锡是主要优势矿种,保有储量居世界之首,其产锡历史可追溯到宋元丰元年(闻广,1980)。据全国以省、自治区、直辖市为单元统计,广西、湖南的锡矿储量分列第二、第三位,江西钨矿储量最大,湖南锡矿石冶炼、加工生产产量居全国之首。
Nanling metallogenic belt is located in the southeastern end of Eurasia, east of the Pacific plate, west and India plate phase, in the Pacific Ocean tectonic domain and Tethyan tectonic domain intersection, across Yangtze and Huaxia two plates. The metallogenic belt is famous for its large amount of granite and rich colored and rare metals (Fu Jianming et al., 2011). Among them, tungsten and tin are the main dominant minerals, with the highest reserves in the world. The history of tin production dates back to the first year of Song Yuanfeng (Wen Guang, 1980). According to statistics from the provinces, autonomous regions and municipalities directly under the Central Government, the reserves of tin ore in Guangxi and Hunan are ranked second and third respectively. Jiangxi has the largest reserves of tungsten ore and the output of tin ore in Hunan ranks first in the country.
