WebbThe Raman shifts from inclusions are normally interpreted as the result of the inclusion being under a hydrostatic pressure. Consequently, the Raman shifts measured from inclusions are directly converted into a hydrostatic pressure [e.g. 10 ], using pressure-wavenumber calibration curves established from hydrostatic DAC experiments.
