Name and quarry location: | Giallo antico, from Chemtou, Tunisia |
Geological description: | Fine-grained limestone, weakly metamorphosed and sheared, with yellow ferruginous stylolites, and scattered euhedral microcrystals of dark orange-brown iron oxide (goethite pseudomorphs after pyrite?) concentrated particularly in the stylolites. |
Comments: | All authorities agree this is giallo antico; marmor numidicum; Numidian yellow from Chimtou (the Roman Smitthus), Tunisia. Corsi had presumably meant Brianza, the area between Milan, Como and Lecco, a source of sandstones and conglomerates but not yellow limestones or marbles (Jervis,1889; passim.) |
