Peinado

Stratovulcano · Argentina · 5741 m

Lighter-colored pyroclastic material blankets the summit of Cerro Peinado, and a possible pyroclastic-flow deposit descends the right-hand flank. This symmetrical Argentinian stratovolcano, one of the youngest in the region, is the source of well-preserved lava flows of Holocene age from summit and flank vents. An apron of pristine lava flows surrounds the volcano and was erupted from the main cone and from vents on the flank, including a prominent ESE-flank vent.

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.

Sintesi da Wikipedia

Riassunto in inglese

Peinado 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.
