• The W mineralizations of Garganta de los Montes (Spanish Central System) is emplaced in a series of migmatized gneisses and seems to be spatially and genetically related to the La Cabrera granitoid. CO2-H2O fluid inclusions, water-rich, and water-rich with different cations, have been recognized in quartz .The dilution of the carbonic-water-rich fluids, and the consequent altering of the chemical and physical characteristics of the mineralizing system, make the W-bearing complexes unstable, which wo ul d have induced W precipitation.
