Abstract
Ion beam induced luminescence (IBIL) was applied, along with cathodoluminescence (CL), on seven samples of marbles of historic and architectural interest. The CL colours, observed in a cold cathode device, have been related with the IBIL spectra. Moreover a detailed analysis of the IBIL spectral features allowed to disclose the influence of the chemical composition and to argue on the crystal-chemical role of the Mn2+. Beyond the chemical information and crystal-chemical interpretation, the spectra are recognised valuable for their significance as fingerprints of marbles in the field archaeological studies giving information of their nature and origin.
