Sintesi geologica
The symmetrical Cerro Peinado stratovolcano in Argentina is the source of well-preserved Holocene lava flows from summit and flank vents (de Silva and Francis, 1991). The upper part of the cone is covered by pyroclastic material. Possible pyroclastic-flow lobes extend to the NW and N. An apron of pristine lava flows that extends to 6 km were erupted from the main cone and from flank vents, including a prominent ESE-flank vent. It is surrounded by small fields of older cinder cones, maars, and lava flows, located along N-S-trending faults, which are related to the Salar de Antofalla and Antofagasta volcanic fields.

Riassunto in inglesePeinado is a stratovolcano in Catamarca Province, Argentina. It consists of a volcanic cone with a summit crater, surrounded at its foot by lava flows erupted from flank vents. It began erupting about 100,000 years ago, with the last eruption about 36,800 years ago. Future eruptions are possible.
