This research involves application of a laser-microprobe apparatus         to analyze released noble gases from individual minerals and fluid              inclusions.  On the one hand released 40 Ar/39 Ar from irradiated               samples will be analyzed via mass spectrometry to date metamorphic              minerals in granulites from Sri Laaka.  The technique potentially will          allow dating of compositionally zoned minerals an, hence, timing of             formation of different rock-forming components.  In addition, the               method can be applied to analysis of noble gases released from                  individual fluid inclusions.  Specifically, selected elements in fluid          inclusions can be converted to noble year species via neutron                   irradiation prior to analysis.  These daughter gases can be analyzed to         determine directly to infer contents of the parent elements in                  individual inclusions.  Such information will provide details                   concerning the history and source of the fluids.
