| Abstract | Fluorite has potential as a proximal indicator mineral for the exploration of specialty metals, particularly rare earth elements and Nb in carbonatiterelated deposits. Plots of Tb/La - Tb/Ca were
generated using all available published data (worldwide) to compare REE concentrations in fluorite from carbonatite, peralkaline-alkaline, Mississippi Valley Type (MVT), and vein (sedimentary, igneous, and metamorphic hosted) deposits. Y-Yb plots
distinguish between fl uorites from carbonatite and MVT deposits. Fluorite from carbonatite-related and MVT deposits form compositional fields with minor overlap. Ongoing investigations include: microchemical analyses of fluorites from key Canadian
and foreign deposits, diagram refinement by contouring, the production of probability plots, and experimentation with discrimination diagrams incorporating normalized REE slope calculations with the presence or absence of Ce and Eu anomalies.
