| Name and quarry location: | Pietra paesina, from Civitavecchia, Rome, Lazio, Italy |
| Geological description: | Micritic limestone or calcareous marl from the Cretaceous-Eocene Alberese Formation. Calcite-filled microfractures control iron-staining. Some dendritic manganese oxides emanate from the fractures. |
| 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. This sample has 'Arg....' [Argilla?] in ink on reverse of specimen but mainly covered by the painted-on specimen number. |
