Determination of carbon and oxygen in fluid inclusions of rocksalt
Abstract
Nuclear microprobe analysis is used to quantitatively characterize fluid inclusions in halite. We show the presence of three types of fluid inclusions located near the surface of rocksalt sections: hydrocarbon, brine + hydrocarbon and brine-rich inclusions. The elemental salt and and inclusion stability has been verified under microbeam investigation with a beam current density up to 26 pA/smm 2. Oxygen and carbon detection limits of 10 -4 molcm -3 were achieved. Moreover, the composition of these fluid inclusions appears to be strongly inhomogeneous.
