Marble analysis, 4810
White marble
Marble origin: Göktepe (Turkey)
Mineralogy: calcite
Texture: homeoblastic
Maximum grain size (MGS): 0.93 mm
δ18OV-PDB: -2.97 ‰
δ13CV-PDB: 2.52 ‰
Cathodoluminescence color: dark blue
Cathodoluminescence intensity: weak
Cathodoluminescence distribution: heterogeneous
Stable isotope data fall in a zone where different source areas (i.e. Carrara, Hymettus, Paros, Thasos, Marmara, Aphrodisias, Afyon, Naxos, 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.
