Marble analysis, 69.14.A
White marble
Marble origin: Göktepe (Turkey)
Mineralogy: calcite
Texture: heteroblastic
Maximum grain size (MGS): 0.40 mm
δ18OV-PDB: -2.23 ‰ -2.24 ‰ -2.11 ‰
δ18OV-PDB: 2.83 ‰ 2.15 ‰ 2.24 ‰
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, Göktepe, Aphrodisias, Afyon) overlap and the data are inconclusive. The color of luminescence, the texture and the MGS are in accordance with Göktepe as the marble origin.
