Within the context of white marble provenance research, 42 powdered white Greek marbles have been characterized using electron paramagnetic resonance (EPR) spectroscopy. Phase analysis was first carried out to separate calcitic and dolomitic marbles, then EPR spectra of Mnuc were studied. Investigation of other marble EPR spectra, especially around g — 2.00, led us to characterize five different signals. The intensities of Mn 2+ lines permit the separatum of eight quarries into two groups, allowing a first discrimination, in the g = 2,00 region, only one signal has been found to be useful for provenance research objectives. The results are cheering and should lead to many other similar experiments.
