Calabozos is a Holocene caldera in central Chile’s Maule Region. It is a member of the Southern Volcanic Zone, one of the three distinct volcanic belts of South America. Calabozo is responsible for the huge Loma Seca Tuff, a body of material 200 cubic kilometres to 500 cubic kilometres in volume.
About Calabozos in brief
Calabozos is a Holocene caldera in central Chile’s Maule Region. It is a member of the Southern Volcanic Zone, one of the three distinct volcanic belts of South America. Calabozo is responsible for the huge Loma Seca Tuff, a body of material 200 cubic kilometres to 500 cubic kilometres in volume. It accumulated over at least three eruptive periods, beginning 800,000 years ago and lasting until 150,000 year ago. The calderA’s dimensions are 26 kilometres by 14 kilometres, and it has an elevation of 3,508 metres. It sits on a historic bed of volcanic and plutonic sedimentary rock that in turn sits on top of a layer of merged sedimentary and metamorphic rock. The majority of the Andean volcanoes formed from the subduction of the oceanic Nazca Plate under the continental South American continental lithosphere. Subduction occurs about 160 kilometers west of Peru and Chile at a rate of 9 to 11 centimetres per year at 30 degrees south. The last eruption occurred during Holocene time, and produced a dacitic lava flow in volume) that extends for 30 kilometres. It also produced the Andean Volcanoic Belt and the rest of the rest of the Holocene epoch of the Chilean Andes. The date of its last known eruption is not known with precision, though it took place during the Kocene, though the last eruption is believed to have taken place in the late Holocene.
It could potentially be useful for geothermal energy for the harvesting of the eastern edge of the Nazca plate under the edge of South American lithosphere, and for the formation of an oceanic trench in the Pacific Ocean in the Trench–Chile region. The vents occur in two clusters, Colorado and Puesto Calabazos, and are located along the margin of a fault at the southwestern edge ofThe caltera is located in an area of poorly glaciated mountains that is not permanently populated. There are no roads, and it is only accessible via horse or on foot. The largest, which is on the southern rim of the calder a, is the Hololithic Cerro del Medio complex with an elevation of 3,.508 metres. It is made mainly of andesite and dacite, and has a volume of 20 cubic kilometres to 25 cubic kilometres. On the southwest edge several eruptions have created the Descabezado Chico volcano ) which consists of four overlapping volcanic craters. The springs are as old as 0. 3 mya, and may have formed directly after Calbozos’s second eruption as a result of uplift caused by re-occurring activity in the calter a. The volcanoes are located near Curicó and Talca, on the western Andes, near the border of Chile and Argentina.
