Abstract
Within the Variscan Karkonosze pluton (NE Bohemian Massif), the Szklarska Por & eogon;ba Huta quarry hosts multistage post-magmatic mineralisation disseminated in aplogranites, pegmatites, and quartz veins, comprising WSn-Mo-Bi and Th-Nb-REE assemblages. In this study, diverse Bi sulphides, sulphosalts, and chalcogenides were identified and characterised, and trace-element compositions of associated base-metal sulphides were determined to reconstruct the crystallisation sequence and metal distribution during hydrothermal fluid evolution. LA-ICP-MS data reveal strong geochemical contrasts between base-metal sulphides from aplogranites and quartz veins. The mineralisation records a transition from late-magmatic to hydrothermal conditions, defining three successive, partly overlapping stages within a mineralising continuum. Early aplogranite-hosted mineralisation was dominated by pyrite-pyrrhotite, accompanied by W-Sn-Mo minerals, other base-metal sulphides, bismuthinite, and bismuth. Pyrite from this stage shows high enrichment in Mo, W, As, Co, and Ni, with progressive Ni depletion relative to Co as temperature decreases. Subsequent quartz-vein mineralisation was initially characterised by abundant W-Sn-Mo minerals associated with Fe-sulphides, which show continued Ni depletion followed by a decrease in Co availability. With progressive cooling, chalcopyrite and sphalerite became dominant, incorporating Cd, Ag, In, and Sn from the mineralising fluids. Bismuth and bismuthinite were also present, accompanied by the crystallisation of rare Pb-Bi-Ag sulphosalts. The late stage was characterised by various CuBi sulphosalts, Bi chalcogenides, and a second generation of base-metal sulphides. Paragenetic and trace-element data indicate that base-metal sulphides and Bi-bearing phases crystallised over a broad temperature range from >= 400 to similar to 200 degrees C during progressive cooling and fluid fractionation, reflecting changes in fS(2) and redox state. These parameters controlled the distribution of base and critical metals among successive mineral assemblages throughout the system evolution. The Szklarska Por & eogon;ba-Huta mineralisation provides new insights into the mechanisms responsible for the development of CRM-bearing granite-related mineralising systems in the Bohemian Massif and Central Europe.
