Dataset to Hintzen et al. (2023): Multistage fluorite mineralization in the southern Black Forest, Germany: evidence from rare earth element (REE) geochemistry, published in European Journal of Mineralogy The Black Forest hosts a wide range of hydrothermal mineralization, including fluorite–barite vein deposits. In a detailed investigation of the Finstergrund and Tannenboden deposits in the Wieden mining district (southern Black Forest), the diversity, geochemical evolution and relative chronology of multistage fluorite precipitation is tracked on the basis of rare earth element (REE) geochemistry, geologic field relationships and crystal zoning. Geochemical discrimination and mathematical lambda coefficients suggest a total of seven fluorite REE groups, at least three distinguishable post-Variscan fluid mobilization events and independent formation histories for the deposits despite their spatial proximity. The local diversity of REE patterns emphasizes the need for detailed investigations of individual hydrothermal vein deposits.
