Marble analysis, 50.109
Limestone
Limestone origin: Libya
Microfacies: biosparite
Bioclasts: fragments of shells
When the artefact was made in the country of its discovery locality (Leptis Magna), the importation of this limestone is not realistically as the subsoil of the region of Libya contains such rocks.
