The crushing of geological samples may lead to changes in their Raman spectrum and to a loss of their texture. The Raman laser spectrometer of the future ExoMars mission will make analyses on powder. We used minerals and rocks to study modifications induced by the crushing process using both Raman mapping on a laboratory instrument and the Raman laser spectrometer simulator.
