Two types of fluids are in volved: a) A low salinity (0.4-4.5 wt% NaCl equiv.) NaCl-H20 fluid is the responsable for the first type of alteration. Temperature was probably close to 3000º b) A moderate to high salinity (15.3-24.5 wt% NaCl equiv.) heterogeneous (liquid + gas) CaCI2-NaCI-H20 fluid was in volved in the second alteration under conditions of Pfluid probably very close to hydrostatic. These alterations probably took place as discrete hydrothermal events of different ages.spajournal articlehttp://www.sociedadgeologica.es/publicaciones_geogaceta.htmlopen access552.3(234.1)PegmatitesCa-alterationsFluid inclusionsSpanish Central System.Petrología
