Cava Del Colle
From the Del Colle quarry, a building and dimension stone known as 'Pietra di Verezzi' was extracted by 'Soc. Escomarmi di F. Bassi' and was definitively closed in 1993. The quarry walls display two main faces characterized by high, smooth cuts, indicating the use of chain cutters for extraction. In earlier periods, however, the area was exploited using helical wire techniques, as evidenced by several surviving iron pulleys located along the quarry margins.
The Verezzi Member is dated to the SerravallianâLanghian [11.63 - 15.98 million years ago] and consists of calcarenites and biocalcarenites varying in color from pinkish to deep red. The red hue results from the enrichment in microgranular hematite, produced by the alteration of clastic of Melogno porphyroids. The 'Pietra di Verezzi' ranges from weakly to strongly cemented. Fossil content includes fragments of echinoids (mainly radioles), bichordites (which are fodinichnia left by echinoids), bivalves such as Aequipecten bollenensis (Mayer-Eymar, 1876), Aequipecten macrotis (G. B. Sowerby I, 1847), Aequipecten malvinae (Du Bois de MontpÃĐreux, 1831), and Talochlamys multistriata (Poli, 1795), as well as brachiopods like Gryphus rovasendianus (Seguenza, 1866), rare solitary corals, and selachian teeth.
