Marble analysis, 4827

Relief fragment: branch of a plane tree with flying bird

White marble
Marble origin: Göktepe (Turkey)


Mineralogy: calcite
Texture: heteroblastic
Maximum grain size (MGS): 0.47 mm
δ18OV-PDB: -2.62 ‰
δ13CV-PDB: 2.20 ‰
Cathodoluminescence color: dark purple
Cathodoluminescence intensity: weak
Cathodoluminescence distribution: homogeneous

Stable isotope data fall in a zone where different source areas (i.e. Carrara, Hymettus, Paros, Thasos, Marmara, Aphrodisias, Naxos, Afyon, Göktepe) overlap and the data are inconclusive. However, the MGS, the texture and the dark purple color of luminescence support Göktepe as the origin of this marble.
