Abstract
Late-stage hydrothermal (â¼20-70â¯Â°C) vein assemblages reported in this study record the transition from deep (>2â¯km) to very shallow (0-1â¯km) crustal conditions. As a consequence of successive uplift, increasing proportions of shallower and cooler (â¼50-70â¯Â°C) fluids could take part in such mixing processes. Associated changes in the fluid composition caused the vein mineralogy to change from sulphide-quartz-fluorite-barite to calcite-anhydrite/gypsum-siderite-dolomite, as the system passively ascended closer to the surface.
