Abstract (EN): Hydrothermal alteration has caused albitization and quartz dissolution within the Geres granite, Portugal. Altered domains within the granite are characterized by a core zone of albitization, and a peripheral zone that contains epidote + vermicular chlorite + calcite + hematite. Homogenization temperatures from authigenic quartz range from 171 to 279 degrees C, with a mode around 220 degrees C. The altered rocks from Geres have very low U and W contents, and W - Mo mineralization in the area is inferred to pre-date albitization and epidote alteration.
