Marble analysis, 51.664
Fragment of a sculpture: left foot
White marble
Marble origin: Afyon (Turkey)
Mineralogy: calcite
Texture: heteroblastic
Maximum grain size (MGS): 0.82 mm
δ18OV-PDB: -5.11 ‰
δ13CV-PDB: 1.45 ‰
Cathodoluminescence color: yellow, brown-orange, dark brown
Cathodoluminescence intensity: intermediate to weak
Cathodoluminescence distribution: heterogeneous
Stable isotope data fall in a zone where different source areas (i.e. Paros, Afyon, Aphrodisias, Naxos, Pentelikon, Afyon) overlap and the data are not conclusive. However, the MGS, the texture and the cathodomicrofacies support Afyon as its origin.
