From: An innovative approach for provenancing ancient white marbles: the contribution of x-ray diffraction to disentangling the origins of Göktepe and Carrara marbles

Figure 3

X-ray powder diffractograms of 18 marble samples from Carrara (image on the top) and Göktepe (image on the bottom). Symbols: Cc = calcite; Grph = graphite; Dol = dolomite; a few diffraction peaks can be assigned to a mica. The small peaks at about 32.6° can be assigned to plagioclase, which could be present in traces.
