【 摘 要 】

Various marbles collected from Moroccan careers, and two white reference marbles originating from Carrare-Italy and Drama-Greece, have been studied by different analytical techniques. Chemical composition of rocks has been determined by X-Ray fluorescence. X-Ray diffraction and Raman spectroscopy allowed the identification of both major (calcite and dolomite) and minor (quartz) mineralogical components. Moreover, Raman spectroscopy has been used to identify the calcium carbonate phases and to examine the graphitic ones in the marbles.
