Breccia of clasts of fine-grained limestone, extensively recrystallised through diagenesis, in a ferruginous micritic matrix. Note areas of coarser crystalline calcite (probably the relics of fossils), and minor dendrites of manganese oxides.

| 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.
