摘 要:本文按矿床成矿系列理论研究方法,初步厘定了滇西地区与燕山期—喜马拉雅期伟晶岩有关的稀有金属宝石矿床成矿系列及亚系列,与第四纪表生作用有关的稀有金属矿床成矿系列及亚系列,研究结果表明本地区在燕山期—喜马拉雅期发生了大规模的中-酸性岩浆侵入活动,并形成众多的伟晶岩,发生了重要的岩浆-热液成矿事件,稀有金属铍、铌、钽、锂、铷、铯等矿产成矿主要与其有关,构成了特定的稀有金属矿产矿床成矿系列。本文初步总结了滇西地区稀有金属矿产资源及其特征、矿床成矿系列及成矿规律,分析了找矿潜力,划分出找矿远景区,深化了该区稀有金属矿产成矿规律认识。Using research methods based on metallogenic series deposit theories,this study preliminarily determined the metallogenic series and sub-series of rare metal and gem deposits related to Yanshanian–Himalayan pegmatite and the metallogenic series and sub-series of rare metal deposits related to quaternary supergenesis.The results indicated that large-scale intermediate-acid magmatic intrusions occurred that produced a number of pegmatite rocks and caused significant magma-hydrothermal metallogenic events in the Yanshanian–Himalayan epoch of this area.Rare metal mineralizations,including Be,Nb,Ta,Li,Rb,and Cs,were mainly related to Yanshanian–Himalayan granite and pegmatite and constituted specific rare metal mineral deposits.This study preliminarily described rare metal mineral resources,their characteristics,and metallogenic series deposits and regularities,and analyzed prospecting potential,delineated prospective areas,and deepened our understanding of the metallogenic regularities of rare metals in West Yunnan.
