CO2-rich fluid inclusions in granulites: evidence for entrapment after the peak of metamorphism Academic Article uri icon

abstract

  • CO2-rich fluid inclusions have been found in samples from granulite-facies terranes around the world. These inclusions, if they were formed during the peak of metamorphism, may provide an important source of information concerning the nature of granulite-facies fluids. In at least some cases, however, CO2-rich fluid inclusions in granulites clearly formed after the peak of metamorphism. Furthermore, investigation of fluid inclusions from the Adirondacks shows that high CO2-densities, a property typically used to infer peak metamorphic formation of these inclusions, may occur in inclusions that were trapped after the peak event. Thus, inferences of peak-metamorphic fluid compositions based on fluid inclusions must be viewed with caution. -Author
