南岭钨锡稀土成矿带资源特征与潜力分析

南岭钨锡稀土成矿带跨越湖南、广东、广西、江西四省(区),其钨、锡、铋、铅锌、稀土等产量位居全国前列,是我国重要的有色金属资源基地和生产加工基地。该成矿带横跨扬子、华夏两个板块,位于中生代欧亚大陆板块构造岩浆活动带的华南陆块中部,区域成矿地质条件优越,是中国有色、稀有、稀土、放射性矿产的重要成矿远景区带。通过研究成矿带的成矿特征,划分了成矿系列,建立了成矿谱系,确定了区带的主攻矿种为钨、锡、锰、铅锌,并对其资源潜力进行了评价,预计可新增钨475万吨、锡375万吨、锰2.6亿吨、铅锌6084万吨。在此基础上,部署了江西省于都-银坑重点远景区、江西大余-上犹重点远景区、广东韶关地区铅锌、银、钨矿重点远景区、广东大宝山-连平地区铁、铜、铅锌、钨矿重点远景区、湖南郴州地区钨、锡、钼、铅锌、铜、萤石矿重点远景区5个重点远景区和湖南常宁地区铅锌、金、银、萤石、硼矿一般远景区等8个一般远景区,为指导本区勘查工作提供了依据。

Characteristics and Mineral Potential of Nanling W Sn REE Metallogenic Belt

Nanling metallogenic belt locates across Hunan province, Guangdong province,Guangxi autonomous region and Jiangxi province. The production of W,Sn, Bi, Pb,Zn and REE is in the forefront of the country. It is one of the important nonferrous metals resource bases and production bases in China. The belt stretching across Yangtz plate and Cathaysian plate, locates in central South China landmass which is in the tectonic- magamatic zone of the Mesozoic Euroasia plate.This belt with favorable geological setting is an important prospective area for nonferrous metals, rare elements, rare earth elements and radioactive minerals. The target commodities are W, Sn, Mn,Pb and Zn. The ore- forming characteristics were studied for the main commodities, and mineralization series and spectrum were built following by the appraisal of the mineralization potential. 5 Key prospective zones were delineated, which are Yudu Yinkeng zone in Jiangxi province, Dayu ShangYou zone in Jiangxi province, Shaoguan Pb- Zn- Ag- W zone inGuangdong province, Dabaoshan Lianping Fe- Cu- Pb- Zn- W zone in Guangdong province and Chenzhou W- Sn- Mo- Pb- Zn- Cu- Fluorite in Hunan province.8 ordinary prospective zones (Changning Pb- Zn- Au- Ag- Fluorite B zone and others) were also delineated. These zones are evidences for further exploration in this belt. This study could support mineral exploration in this metallogenic belt.
