White marble
Marble origin: 
8426: Paros (Paros-Marathi) (Greece)
8426 I and 8426 II: Carrara (Italy)

8426 
Mineralogy: calcite
Texture: heteroblastic
Maximum grain size (MGS): 1.86 mm
δ¹⁸O_V-PDB: -3.37 ‰
δ¹³C_V-PDB: 5.32 ‰
Cathodoluminescence color: purple
Cathodoluminescence intensity: weak
Cathodoluminescence distribution: homogeneous

All data are in accordance with Paros (Paros-Marathi) as the marble origin.
 

8426 I and 8426 II
Mineralogy: calcite
Texture: homeoblastic
Maximum grain size (MGS): 0.82 mm (8426 I);  0.54 mm (8426 II) 
δ¹⁸O_V-PDB: -0.38 ‰ (8426 I);  -1.71 ‰ (8426 II) 
δ¹³C_V-PDB: 1.92 ‰ (8426 I);  2.80 ‰  (8426 II) 
Cathodoluminescence color: brown-orange 
Cathodoluminescence intensity: intermediate 
Cathodoluminescence distribution: homogeneous

Stable isotope data fall in a zone where different source areas (i.e. Paros, Thasos, Marmara, Carrara, Hymettus) 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.
