Marble analysis, 8066
Fragment of sarcophagus: head of Aetas (Summer)
White marble
Marble origin: Marmara (Turkey)
Mineralogy: calcite
Texture: heteroblastic
Maximum grain size (MGS): 1.40 mm
δ18OV-PDB: -0.74 ‰
δ13CV-PDB: 3.16 ‰
Cathodoluminescence color: dark blue
Cathodoluminescence intensity: weak
Cathodoluminescence distribution: homogeneous
Stable isotope data fall in a zone where different source areas (i.e. Paros, Thasos, Marmara, Carrara, Hymettus) overlap and the data are inconclusive. However, the texture and the dark blue color of luminescence support Marmara as the origin of this marble.
