Corsi 942, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History
| OUMNH Number: | 942 |
|---|---|
| Name and quarry location: | Tartaro di Tivoli, from Tivoli, Rome, Lazio, Italy |
| Geological description: | Compact banded travertine composed of fibrous to very finely acicular calcite crystals, perhaps originally aragonite. |
| Comments: | The name 'tartaro' is probably derived from the resemblance of some calcareous precipitates to the encrustrations of potassium bitartrate (‘tartar’) deposited in wine casks during fermentation. It has also been suggested that Corsi’s samples are named after Lago di Tartaro, a location close to Tivoli. Other examples of this stone are uncommon. |
