Marble analysis, 8427

Female bust


White marble
Marble origin: Göktepe (Greece)


Two samples were analyzed: body (8427/2005-32), head (8427/2005-33)

 

Mineralogy: calcite
Texture: homeoblastic
Maximum grain size (MGS): 0.47 mm (body: 8427/2005-32);  0.51 mm (head: 8427/2005-33)
δ18OV-PDB: -2.72 ‰  -2.33 ‰ (body: 8427/2005-32);  -2.29 ‰  -2.41 ‰ (head: 8427/2005-33)
δ13CV-PDB: 2.46 ‰  2.81 ‰ (body: 8427/2005-32);  2.93 ‰  2.84 ‰ (head: 8427/2005-33)
Cathodoluminescence color: 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, Afyon, Aphrodisias, Göktepe) overlap and the data are inconclusive. However, the MGS, the texture, and the blue color of luminescence support Göktepe as the origin of this marble.
