湖南省仁里矿区仁里矿段钽铌矿成矿地质特征的探讨

Kernel in the mining area in hunan province in the kernel ore block of tantalum niobium ore mineralization geological features

仁里矿区位于扬子准地台东南缘之江南地轴中段,幕阜山花岗岩体南缘,属花岗岩与冷家溪群片岩内外接触带之伟晶岩密集区,稀有金属成矿远景区。目前仁里矿区钽铌矿找矿已突得突破,为湖南省2017年度重点找矿突破项目。本文通过区域地质背景和矿区地质背景、伟晶岩特征及矿床地质特征等方面对仁里矿区的仁里矿段花岗伟晶岩型铌钽矿成矿地质特征进行探讨。

The Renli mining area is located in the middle of the south of the Yangtze River in the south of the Yangtze River, and the southern margin of the Mesopotamia granite body belongs to the pegmatite-dense zone and the rare metal mineralization prospecting area of the granite and the cold-and- At present, the exploration of tantalum and niobium ore in Renli mining area has been a breakthrough, and it is a breakthrough project of Hunan Province in 2017. In this paper, the metallogenic geological characteristics of granite-type niobium-tantalum ore in Yanli ore section of Renli mining area are discussed through regional geological background and geologic background, meta-crystal characteristics and geological features of det-osit.
