Les inclusions fluides des enclaves catazonales de Bournac (Massif central)

Abstract
The catazonal xenoliths occurring in the Bournac volcano (French Massif central) contain many « carbonic » fluid inclusions (CO₂, eventually hydrocarbons), and, more rarely some aqueous ones (only in the granitic xenoliths). PT estimates from fluid inclusions (CO₂ isochores, density between 1.075 and 0.72 g/cm³) agree with corresponding estimates derived independantly from the solid phases.
