The two Canteras la Ponderosa, S.A. production centres in Spain are located in the mountain region of the Catalan Coastal Range:
The Alcover quarry is rich in material from the TRIASSIC geological period, specifically the LOWER MUSCHELKALK sub-period, with an average thickness of 70-90 m, and consisting of microcrystalline limestone.
The Riudecols mine, designated Puig Mari, is rich in Palaeozoic (Carboniferous) materials used for a large number of granodiorite dykes, associated with granitic plutons that appear to the north and east of the area.
These plutons represent the base of Priorato's structural unit.
