Noble gas solubility in super-critical water: implications for inert gas studies and geochronology
Contenido principal del artículo
Resumen
Los gases inertes exhiben idealmente solubilidad infinita en agua supercrítica. Las implicaciones de este fenómeno son discutidas en el contexto del reestablecimiento del sistema K-Ar durante metamorfismo regional y emplazamiento de granitos. Las abundancias de los gases inertes en rocas y lutitas del suelo marino, posiblemente puedan ser interpretadas como consecuencia (al menos en parte) de partición entre agua y fases silicatos en las que los gases inertes ligeros son tomados preferentemente en agua. El desempeño del agua supercrítica como un medio de transporte para gases inertes, ofrece una importante alternativa a los procesos poco probables de difusión volumétrica a bajas temperaturas.
