Marble analysis, 3934

Statue of Isis Pelagia

White marble
Marble origin:
Sample 3934: Paros-Chorodaki (Greece)
Sample 3934 I: unknown
Samples 3934 II, 3934 III et 3934 IV: Carrara (Italy)

Sample 3934
Mineralogy: calcite
Texture: heteroblastic
Maximum grain size (MGS): 2.80 mm
δ¹⁸O_V-PDB: -4.21 ‰
δ¹³C_V-PDB: 1.69 ‰
Cathodoluminescence color: brown-pink
Cathodoluminescence intensity: weak
Cathodoluminescence distribution: homogeneous

Stable isotope data fall in a zone where different source areas (i.e. Marmara, Paros, Aphrodisias, Afyon, Naxos) overlap and the data are not conclusive. However, the MGS, the texture and the brown-pink color of luminescence support Paros-Chorodaki as the origin of this marble.

Sample 3934 I
Mineralogy: calcite
Texture: heteroblastic
Maximum grain size: 0,64 mm
δ¹⁸O_V-PDB: -7.43 ‰
δ¹³C_V-PDB: 2.16 ‰
Cathodoluminescence color: brown-orange
Cathodoluminescence intensity: intermediate
Cathodoluminescence distribution: homogeneous

The texture, the MGS and the cathodomicrofacies are in accordance with Carrara as the marble origin. The isotope data do not match any with the Carrara data.
