The Altiplano-Puna Volcanic Complex is an ignimbritic plateau situated between 21° and 24°S and straddling Chile, Bolivia and Argentina (de Silva, 1989) in the Andean Central Volcanic Zone (CVZ; Fig. 1a).The 10-1 Ma ignimbrite flare-up that formed this plateau represents higher eruption rates than typical of continental arcs (de Silva and Gosnold, 2007) The Altiplano-Puna Volcanic Complex was one of the most volcanically active places on Earth starting about 10 million years ago. During that time, several super volcanoes had produced massive eruptions and created a large complex of collapsed calderas. Such a major eruption hadn't occurred over the last several thousand years despite the area being still active.

The Altiplano (Spanish for high plain), Collao (Quechua and Aymara: Qullaw, meaning place of the Qulla) or Andean Plateau, in west-central South America, is the area where the Andes are the widest. It is the most extensive area of high plateau on Earth outside Tibet.The bulk of the Altiplano lies in Bolivia, but its northern parts lie in Peru, and its southern parts lie in Chile and Argentina An enormous dome has been discovered growing in the Central Andes above the world's largest active magma store. Found in the Altiplano-Puna Plateau - the second highest plateau on the planet - the dome stretches more than a kilometre high (3,280 feet), making it 172 metres taller than the world's tallest building in Dubai.Researchers say this massive structure is the result of an injection. Evidence of large volumes of such melts has been also proposed by geophysical methods (i.e. the Altiplano-Puna Magma Body; Chmielowsky et al., 1999) In this work, petrography and whole rock, mineralogical and melt inclusions geochemistry of a glassy lava flow of Toconce volcano are presented. Petrographically, this lava flow shows a porphyric texture, with euhdral to subhedral plagioclase.

Four multicyclic complex calderas and smaller ignimbrite shields located within the Altiplano Puna Volcanic Complex of the Central Andes (APVC) erupted 13000 km³ of magma within the last 11 Ma. One of the largest and most complex of these is the Cerro Guacha Caldera. Ar-Ar age determinations and paleomagnetic directions suggest that the Cerro Guacha Caldera was formed by two major eruptions.

Pastos Grandes has erupted a number of ignimbrites through its history, some of which exceeded a volume of 1000km3. After the ignimbrite phase, the lava domes of the Cerro Chascon. Discussion on backarc mantle melting in the central Andean subduction zone, based on results of magnetotelluric studies Altiplano-Puna-Volcanic-Complex. Recent ignimbrite eruptions are older than 1Ma. The high water, phenocrystal and silicate content signify long storage in huge crustal magma chambers with pronounced fluidal circulation. Holocene volcanic activity is less than in the Puna.

Transects A-A 0, B-B , and C0-C correspond to the cross sections shown in Figures 7, 8, and 9, respec-tively. The convergent motion of. The Altiplano (Spanish for high plain), Collao (Quechua and Aimara: Qullaw, meaning place of the Qulla), Andean Plateau or Bolivian Plateau, in west-central South America, where the Andes are at their widest, is the most extensive area of high plateau on Earth outside Tibet. The bulk of the Altiplano lies within Bolivian and Peruvian territory while its southern parts lie in Chile and. Die rote Linie markiert den Bereich, in dem durch seismische Messungen das Magmafeld (Altiplano-Puna Ultrlow Velocity Zone = APULVZ) unterhalb des Altiplano verortet werden konnte. X- und Y-Achse geben Längen- und Breitengrade der vermessenen Region an. Weite Abschnitte der Anden sind durch Vulkanismus entstanden, der sich unter anderem aus Gesteinsmaterial der Nazca-Platte speist: Sie taucht. Die Puna genannte Landschaft hat teilweise den Charakter einer Vollwüste, teilweise sorgen Ichugräser und Büsche für einen steppenhaften Eindruck. Salzseen und zum Teil aktive Vulkane sowie heiße Quellen bestimmen das einzigartige Landschaftsbild. Der Vulkanismus auf den Altiplano ist zurückzuführen auf das Abtauchen der Pazifischen Platte unter die Südamerikanische Kontinentalplatte.

Climate. In extentum, the climate is cool and humid to semi-arid and even arid, with mean annual temperatures that vary from 3°C near the western mountain range to 12°C near Lake Titicaca; and total annual rainfall that ranges between less than 200 mm to the south west to more than 800 mm near and over Lake. The Purico complex is a Pleistocene volcanic complex in Chile close to Bolivia, formed by an ignimbrite, several lava domes and stratovolcanoes and one maar. It is one of the Chilean volcanoes of the Andes, and more specifically the Chilean segment of the Central Volcanic Zone, one of the four volc
