Abstract
The unique geochemical properties of fluorite make it a natural carrier of rare earth elements(REEs).Its REE distribution patterns can effectively record the evolutionary processes of ore-forming fluids.This paper reviews the REE geochemical tracing techniques for fluorite,with a focus on explaining the geological interpretation pathways of characteristic parameter combinations,including total REE content(∑REE),LREE/HREE ratio,Y/Ho ratio,δEu-δCe anomalies,and Tb/Ca-Tb/La discriminant diagrams.Through decoupling REE distribution patterns,an element fractionation model for ore material migration-precipitation processes is constructed.Based on differences in REE complexation behaviors,we invert the evolution of physicochemical conditions(temperature/pH/salinity)in hydrothermal systems.Combined with spatial field analysis of typical parameters,a discriminant matrix for genetic types of ore deposits is established.This study proposes a technical framework for multi-parameter joint inversion,providing a geochemical basis for fluorite prospecting prediction and offering methodological guidance for implementing the new round of prospecting breakthrough strategy.关键词
