Name and quarry location: | Giallo antico, from Chemtou, Tunisia |
Geological description: | Fine-grained limestone, extensively recrystallised through diagenesis, with slender ferruginous veins. Note areas of coarser crystalline calcite, probably the relics of fossils. The colour has changed to pink as a result of heating. |
Comments: | All Corsi's samples of giallo antico from Chemtou, Tunisia (0022-0034) are correctly identified, and they show 'quarry variation' particularly well. Giallo antico is regarded as the finest of all the yellow marbles, although the very best Siena marble can be comparable. The matrix in giallo antico is red or brown; that of brecciated varieites of Siena is purple. |
