Ofiolite di Ca' de Giannasi, Frassinoro, Provincia di Modena, Emilia-Romagna, Italia

In this area ophiolitic masses (basalts, serpentinites, hydrothermalites) outcrop on both sides of the road leading to Tuscany through the Radici Pass. On the right side of the road there is a quarry that is occasionally exploited for road-paving gravel (see coordinates). In this quarry five lithologically and mineralogically different areas are present.
