AB Fluids related to veins and hydrothermal alterations from the Spanish Central System have been studied. Fluid chemistry hasbeen established using microthermometry and Raman spectroscopy. Special attention has been paid to the evolution of P–Tconditions from early H2O–NaCl–CO2–CH4 to later H2O–NaCl–CaCl2 fluids. The different types of fluid systems investigatedcan be distinguished by their fluid pressure, temperature and salinity features. Under initial conditions the fluid pressure may behigh, at lithostatic values, and show a nearly isobaric evolution. The later aqueous fluids drop to hydrostatic pressure with atransition to low pressures, in part due to uplift and erosion.
