Marble analysis, 77.1.A
White marble
Marble origin: Paros (Paros-Chorodaki) (Greece) or Marmara (Turkey)?
Mineralogy: calcite
Texture: heteroblastic
Maximum grain size (MGS): 1.98 mm
δ18OV-PDB: -2.78‰ -3.15‰
δ13CV-PDB: 2.50‰ 2.52‰
Cathodoluminescence color: blue
Cathodoluminescence intensity: weak
Cathodoluminescence distribution: homogeneous
The isotopic values are situated in the Paros and Marmara fields, two marbles with blue luminescence. It seems most probable that this statue was carved from a marble of Paros-Chorodaki, but we do not exclude an origin of Marmara.
