White marble
Marble origin: Göktepe (Turkey)

 

Mineralogy: calcite
Texture: homeoblastic
Maximum grain size (MGS): 0.51 mm
δ18OV-PDB: -2.13 ‰
δ13CV-PDB: 2.78 ‰
Cathodoluminescence color: light and dark purple 
Cathodoluminescence intensity: weak
Cathodoluminescence distribution: heterogeneous

Stable isotope data fall in a zone where different source areas (i.e. Göktepe, Carrara, Thasos, Afyon, Marmara, Paros, Hymettus) overlap and the data are not conclusive. However, the MGS, the texture and the purple color of luminescence support Göktepe as its origin.
