Marble analysis, 51.2873

Bust of a youth


White marble
Marble origin: unkown 

 

Mineralogy: calcite
Texture: heteroblastic
Maximum grain size (MGS): 1.63 mm (51.2873 I);  0.46 mm (51.2873 II) 
δ18OV-PDB: -2.99 ‰ (51.2873 I);  -1.72 ‰ (51.2873 II)
δ13CV-PDB: 1.62 ‰ (51.2873 I);  2.28 ‰ (51.2873 II)
Cathodoluminescence color: brown-pink and brown-red
Cathodoluminescence intensity: weak
Cathodoluminescence distribution: heterogeneous

Stable isotope data fall in a zone where different source areas (i.e. Carrara, Göktepe, Paros, Thasos, Marmara) overlap, and the data are inconclusive. The cathodomicrofacies and the MGS are not conclusive.
