Calcare di Aurisina (Italy) | |
The Calcare di Aurisina (Also known as Aurisina Formation, "Formazione di Monrupino", Trieste Karst Limestone formation, "Tomaj Limestone", "Repen formation", "Sežana formation" and "Lipiza/Lipica formation") is a Mesozoic geologic formation in Italy and Slovenia. This limestones are found in the Trieste area and are of Late Cretaceous (Santonian-Campanian) age, being a local record of Carbonate platform limestones, historically quarried by cutting large blocks using steel wire, what has allowed more access to them, as numerous quarries allow excellent exposure. Due to being cut into large blocks and slabs, that usually end stored near the quarries, detailed, three-dimensional study of the rock's composition and fossils can be easily done.
