Montresta, Provincia di Oristano, Sardegna, Italia


Numerous exposures of andesitic and altered basaltic rocks within a large area around Montresta.

Best sites are:
1) Crossroad to Padria villge, on Montresta - Villanvoa Monteleone road.
2) On the left side of the road that from Villanova Monteleone leads to a river named Torrente Camarraxius, mainly 50 m before the bridge.
3) On the right side of the roa that from Montresta leads to Padria, before the crossroad for Padria-Villaniova Monteleone, at miliar signal "Km 15", into an altered andesite.
4) Along a road which starts at the end of Montresta Village in direction of Padria, around 100 m after the beginning of this secondary road, into a conmpletely altered andesite.
