Marble analysis, 56.2.A

Head of a Genius

White marble
Marble origin: Marmara (Turkey) or Paros (Paros-Choriodaki) (Greece)?


Mineralogy: calcite
Texture: heteroblastic
Maximum grain size (MGS): 1.40 mm
δ18OV-PDB: -0.43 ‰
δ13CV-PDB: 3.00 ‰
Cathodoluminescence color: blue-pink and brown-red
Cathodoluminescence intensity: weak 
Cathodoluminescence distribution: heterogeneous

Stable isotope data fall in a zone where different source areas (i.e. Paros, Thasos, Carrara, Marmara) overlap and the data are inconclusive. However, the color of luminescence support Marmara or Paros as the origin of this marble.
