Abstrakt (anglicky)
   The present study reports the Raman data for reduced carbonaceous matter (CM) in crystalline marbles in relation to the determination of the provenance. Raman microspectrometry was tested on "graphitic" marbles formed under different metamorphic conditions (regional vs. contact), with various geological ages and with distinct types of CM from the Bohemian Massif (Czech Republic). The Raman results exhibited spectral variations of CM with different metamorphic grades and types where several marble groups could be distinguished: (1) well-ordered CM/graphite of higher-grade regional metamorphosed marbles; less graphitised metamorphosed organic matter ("disordered" CM) (2) low-grade regional metamorphosed rocks and (3) contact metamorphosed marbles.
