• Resumen

  • The isotopic composition of carbonates related to the skarn and contact metamorphic aureole of La Maladeta batholith show a broad range of variation. The whole set of obtained data can be modeled by means of an isotopic exchange between a fluid equilibrated with a magma, with an isotopic composition of d18OsMow =8-5% and unknow d13CPDB at XCO2 <0.02 and a Devonian limestone of d18OSMOW= 28- 29% d13CPDB= 4-5% Volatilization processes have been observed previosly to isotopic exchange.
