CAI minerals show spectra CL curvesexceeding the 450,000 a.u. with a large homogeneity along the white inclusions.CL curve features fit perfectly with terrestrial patterns of stressed specimensof weathered marble and limestone in which hydroxyl groups maybe involved. Crypto-clusters of CaCO3, undetectable by means of EPMA,EDS, and Micro-Raman techniques, coupled to the CAI phases are inferredfrom the spectral CL data and from the carbon and calcium contentsprovided by the EDS probe. %~
