赣州南部地区离子吸附型稀土矿成矿花岗岩特征分析

Analysis of metallogenic granite characteristics of ion adsorption rare earth deposits in southern Ganzhou

赣州南部地区是我国离子吸附型稀土矿的重要产地之一,以储量丰富、品位高、配分齐全而闻名于世。根据已控制的大量稀土矿床及稀土资源,本文通过花岗岩时代、产状、岩石学特征、矿物成份、结构构造及成矿物质来源几个方面分析了赣州南部地区离子吸附型稀土矿的成矿花岗岩特征。

Southern Ganzhou is one of the important producing areas of ion adsorption rare earth minerals in China.It is famous for its rich reserves,high grade and complete distribution.According to a large number of controlled rare earth deposits and rare earth resources,this paper analyzes the metallogenic granite characteristics of ion adsorption rare earth deposits in southern Ganzhou from the aspects of granite age,occurrence,petrological characteristics,mineral composition,structural structure and metallogenic material source.
