湖南省战略性矿产矿床类型与找矿方向——以稀贵金属为例

Types and prospecting direction of strategic mineral deposits in Hunan Province: a case study of rare and precious metals

湖南省地处长江中下游南岸,横跨扬子和华夏两大构造单元,具备优越的成矿地质条件,战略性矿产—稀贵金属资源分布广、类型多,显示了巨大的资源潜力。本文基于已有勘查、研究成果,分析研究了湖南省稀贵金属资源分布与矿床类型,指出省内今后稀贵金属找矿方向。研究认为省内稀贵金属找矿以在湘东北地区寻找"仁里式"伟晶岩型稀有金属矿床、在"金腰带"上寻找"大万式"蚀变岩型金矿床为重点,并从加大战略性矿产勘查力度、矿产勘查开发绿色环保要求等方面提出几点思考。

Hunan Province is located in the South Bank of the middle and lower reaches of the Yangtze River,across the Yangtze and Cathaysian tectonic units,with superior metallogenic geological conditions.The strategic mineral such as rare and precious metal resources are widely distributed,many types,showing great resource potential.Based on the existing exploration and research results,this paper analyzes the distribution of rare and precious metal resources and deposit types in Hunan Province,and points out the future prospecting direction of rare and precious metals in Hunan Province.It is considered that the exploration of rare and precious metals in the province should focus on the "Renli type" pegmatite type rare metal deposits in Northeast Hunan and the "Dawan type" altered rock type gold deposits in the "gold belt".Some thoughts are put forward from the aspects of strengthening strategic mineral exploration and green environmental protection requirements for mineral exploration and development.
