摘要
江西宜春雅山铌钽矿是钦杭成矿带上以铌钽为主,伴生有锂、铷、铯等稀有金属的超大型综合矿床。长期以来,对雅山铌钽矿的成矿机制存在不同的认识,在系统的野外实地调查基础之上,总结了铌钽矿成矿特征,分析了矿床成矿机制及矿床成因。雅山地区铌钽矿为岩浆晚期交代矿床,岩浆高度分异演化实现了铌钽等稀有金属元素的初始富集,岩浆期后热液流体的交代作用才是该地区铌钽矿成矿的关键因素。
The Yashan niobium-tantalum deposit at Yichun,Jiangxi province,is a super-large synthetic deposit with lithium,rubidium,cesium and other rare metals.For a long time,there have been different points of view of the metallogenic mechanism of the niobium and tantalum ore deposit.Based on the systematic field investigation,this paper summarizes the mineralization characteristics of niobium and tantalum ore deposit,and analyzes the metallogenic mechanism and genesis of the ore deposit.The deposit in Yashan area are magmatic metasomatism deposits,and the magmatic height differential evolution realizes the initial enrichment of rare metal elements such as niobium and tantalum.
