Puyehue-Cordon Caulle

Stratovolkan · Chile · 2236 m

The Puyehue-Cordón Caulle volcanic complex forms the horizon in this view looking north across the Río Gol Gol valley from the Antillanca volcano group. Flat-topped 2236-m-high Puyehue volcano (right) is a late-Pleistocene to Holocene basaltic-to-rhyolitic stratovolcano constructed above a 5-km-wide caldera and capped by a 2.4-km-wide summit caldera. Historical eruptions originally attributed to Puyehue are now known to be from the Cordón Caulle rift zone, the long snow-covered ridge that extends across the photo to the left of Puyehue.

Ringkasan geologi

The Puyehue-Cordón Caulle volcanic complex (PCCVC) is a large NW-SE-trending late-Pleistocene to Holocene basaltic-to-rhyolitic transverse volcanic chain SE of Lago Ranco. The 1799-m-high Pleistocene Cordillera Nevada caldera lies at the NW end, separated from Puyehue stratovolcano at the SE end by the Cordón Caulle fissure complex. The Pleistocene Mencheca volcano with Holocene flank cones lies NE of Puyehue. The basaltic-to-rhyolitic Puyehue volcano is the most geochemically diverse of the PCCVC. The flat-topped, 2236-m-high volcano was constructed above a 5-km-wide caldera and is capped by a 2.4-km-wide Holocene summit caldera. Lava flows and domes of mostly rhyolitic composition are found on the E flank. Historical eruptions originally attributed to Puyehue, including major eruptions in 1921-22 and 1960, are now known to be from the Cordón Caulle rift zone. The Cordón Caulle geothermal area, occupying a 6 x 13 km wide volcano-tectonic depression, is the largest active geothermal area of the southern Andes volcanic zone.

Ringkasan Inggris

Puyehue and Cordón Caulle are two coalesced volcanic edifices that form a major mountain massif in Puyehue National Park in the Andes of Ranco Province, in the South of Chile. In volcanology this group is known as the Puyehue-Cordón Caulle Volcanic Complex (PCCVC). Four volcanoes constitute the volcanic group or complex, the Cordillera Nevada caldera, the Pliocene Mencheca volcano, Cordón Caulle fissure vents and the Puyehue stratovolcano.
