Fluorite is a strategically important nonmetallic mineral,the research on its genesis is of significant importance.This paper reviews the progress of genetic research methods in order to promote the in-depth study of the genesis of domestic fluorite deposits and make a contribution to a new round of prospecting breakthrough strategy.The distribution characteristics and genetic types of fluorite deposits worldwide and in China are sum-marized.Furthermore,the current status and progress of the main research methods in fluid inclusions,ore-form-ing fluids and material sources,and ore-forming geochronology are reviewed.The fluid inclusion assemblage and in-situ composition techniques of single fluid inclusion of fluorite are summarized,and the source of H-O-Sr-Ca-Nd isotope tracer and the fine reflection of in-situ trace rare earth elements on the mineralization process are discussed.The author proposes that the in-situ analysis technique should be employed to test the fluid inclusions and fluorite components,thereby enabling a more accurate description of the evolution process of ore-forming fluid components.The application of Lu-Hf,U-Pb,Sm-Nd,(U-Th)/He and fission track geochronology of fluo-rite is not only important for the accurate determination of the ore-forming age of fluorite-bearing deposits,but also necessary for the correct interpretation of deposit uplift and denudation in ore-forming exploration.
