湖南省仁里铌钽矿床地质特征及找矿标志

Geological Characteristics and Prospecting Criteria of Ni-Ta Deposit in Renli, Hunan Province

湖南省仁里铌钽矿床位于幕阜山岩体西南缘,为我国东部少有的高品位超大型花岗伟晶岩型铌钽矿床。目前普查工作仍在进行,为了下一步普查勘查设计工作,本文结合矿区勘查成果资料及最新研究成果资料,通过对矿区内的地层、构造、岩浆岩、围岩蚀变、矿体地质特征等进行分析,总结了区内找矿标志。

The Renli Ni-Ta ore deposit of Hunan Province is located at the southwest margin of Mufushan rock mass,is a infrequent high-grade super-large granite-pegmatite Ni-Ta deposits in eastern China.The census is still under way,for the next census survey design work,this paper combines the data of mine exploration results and the latest research results,through the analysis of strata,structure,magmatic rock,wall rock alteration and geological characteristics of ore body in the mining area to summarize the signs of prospecting in the area.
