Marble analysis, 8425

Portrait of a young woman ('Julia Titi')

White marble
Marble origin: Carrara (Italy)

Two samples were analyzed: 8425, ad 8425 I
Mineralogy: calcite
Texture: heteroblastic
Maximum grain size (MGS): 0.54 mm (8425) ; 0.37 mm (ad 8425 I)
δ¹⁸O_V-PDB: -3.28 ‰ (8425); -1.40 ‰ (ad 8425 I)
δ¹³C_V-PDB: 1.80 ‰ (8425); 2.43 ‰ (ad 8425 I)
Cathodoluminescence color: brown-orange
Cathodoluminescence intensity: intermediate
Cathodoluminescence distribution: homogeneous

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