Name and quarry location: | Pietra paesina, from Civitavecchia, Rome, Lazio, Italy |
Geological description: | Heavily fractured micritic limestone with sparry calcite-filled fractures and stylolites. Ferruginous staining is constrained by the fractures giving the 'paesina' effect. It is almost certainly from the Cretaceous to Eocene Alberese Formation. |
Comments: | This most probably comes from the Tolfa Mountains a few miles north of Civitavecchia, an occurrence of pietra paesina described by Civitelli in 1970. Pietra paesina has been found in the Monterano nature reserve. |
