摘要
Abstract
This paper reviews recent research advances in the classification,ore-forming fluids,source of metallogenic materials,and mineralization mechanisms of granite-type rare metal deposits.Research results show that granite-type rare metal deposits typically exhibit a high degree of fractional crystallization,characterized by high evolution,high silica content,peraluminous composition,alkalinity enrichment,abundance of volatile components such as F,Cl,and B,and enrichment in rare metal elements like Li,Nb,Ta,Rb,Cs,and W.The evolution of metallogenic fluids often undergoes two stages:magmatic and hydrothermal.Rare-metal granites are closely associated with S-type granites.Their metallogenic materials are primarily derived from crustal magmas,but incorporate contributions from mantle sources.Magmatic crystallization differentiation and hydrothermal metasomatism are the two main metallogenic mechanisms of granite-type rare metal deposits.关键词
