Short summary
The diversity of chemical patterns in multi-stage fluorite mineralization from two neighbouring deposits in the Black Forest is investigated. From over 70 samples, 7 fluorite groups and 3 hydrothermal events are identified after chemical and mathematical classification. The relative chronology and features suggest different mineralization histories and source aquifers for both deposits despite their proximity. Genetic differences are likely controlled by different behaviours of their host rocks.
