Marble analysis, 4805
White marble
Marble origin: Marmara (Turkey)
Mineralogy: calcite
Texture: heteroblastic
Maximum grain size (MGS): 2.42 mm
δ18OV-PDB: -3.54 ‰ -3.93 ‰ -3.77 ‰
δ13CV-PDB: 2.20 ‰ 2.79 ‰ 2.86 ‰
Cathodoluminescence color: dark blue and purple
Cathodoluminescence intensity: weak
Cathodoluminescence distribution: homogeneous
Stable isotope data fall in a zone where different source areas (i.e. Paros, Thasos, Marmara, Carrara, Hymettus, Göktepe, Aphrodisias, Afyon, Naxos, Pentelikon) overlap and the data are inconclusive. The color of luminescence, the texture and the MGS are in accordance with Marmara as the marble origin.
