| OUMNH Number: | 511 |
|---|---|
| Name and quarry location: | Alberese limestone, from Florence, Tuscany, Italy; and most probably from Valdarno |
| Geological description: | Micritic limestone or calcareous marl from the Upper Cretaceous Alberese Formation. Fractures are calcite-filled. |
| Comments: | Only very slight 'paesina' effect (microfracture controlled iron-staining) is evident, and under no circumstance could this stone be called 'verde'. It is an example of Alberese limestone (described in Price, 2007). |
