Marble analysis, 50.1321

Fragment of the statuette of a river god


White marble
Places of origin: 
50.1321 and 50.1321 I: Marmara (Turkey)
50.1321 II:  Marmara (Turkey) or Paros (Greece) 
50.1321 III: Carrara (Italy)

 


Sample 50.1321 and 50.1321 I
Mineralogy: calcite
Texture: heteroblastic
Maximum grain size: 3.38 mm (50.1321); 1.63 mm (50.1321 I)  
δ18OV-PDB: -0.36 ‰ (50.1321); -0.91 ‰ (50.1321 I)
δ13CV-PDB: 3.36 ‰ (50.1321); 3.31 ‰ (50.1321 I)
Cathodoluminescence color: blue-purple, mauve and brown (50.1321); brown-pink (50.1321 I)
Cathodoluminescence intensity: weak
Cathodoluminescence distribution: heterogeneous (50.1321); homogeneous (50.1321 I)

The isotopic signature, the MGS, the texture and the color of luminescence of this marble support Marmara as its origin.

 

Sample 50. 1321 II
Mineralogy: calcite
Texture: heteroblastic
Maximum grain size: 1.67 mm
δ18OV-PDB: -2.96 ‰
δ13CV-PDB: 2.52 ‰
Cathodoluminescence color: brown-pink
Cathodoluminescence intensity: weak
Cathodoluminescence distribution: homogeneous 

The isotopic values are situated in the Paros and Marmara fields, two marbles with weak luminescence. It seems most probable that this statue was carved from a marble of Paros-Chorodaki, but we do not exclude an origin of Marmara.

 

Sample 50.1321 III
Mineralogy: calcite
Texture: homeoblastic
Maximum grain size: 0.53 mm
δ18OV-PDB: -1.92 ‰
δ13CV-PDB: 2.09 ‰
Cathodoluminescence color: orange and brown-orange
Cathodoluminescence intensity: intermediate
Cathodoluminescence distribution: heterogeneous

Stable isotopic signature fall in a zone where different source areas (i.e., overlap and the data are not conclusive. However the MGS, the texture and the orange color of luminescence support Carrara as its origin.
