   The Raman spectra of metamorphosed carbonaceous material (CM) were obtained in so-called graphitic marbles from several sites in the Bohemian Massif (Czech Republic). Three types of Raman spectra allowed the discrimination between (1) well-ordered CM-graphite of high-grade regional metamorphosed marbles, (2) CM of contact metamorphosed marbles and (3) amorphous organic compounds as "disordered" CM of low-grade regional metamorphosed marbles. Raman microspectrometric analysis revealed the coexistence of carbonaceous particles exhibiting different degrees of graphitization within one marble sample. For the first time, Raman spectra measured on reduced CM grains permitted one to distinguish marbles of different origin and propose their utilization in the provenance determination.
