The origin of these magmas appears to relate to the Altiplano-Puna magmatic physique, which generates melts by differentiation of basaltic magmas first to andesites and then to dacites before being transferred to the shallow crust below Uturuncu from where it was then erupted through buoyancy-dependent processes. This only weakly erosive glacier deposited five units of moraines up to 5 metres (16 ft) excessive throughout the shallow valley; the bottom of these lies at 4,800-4,850 metres (15,750-15,910 ft) elevation and appears to be a product of an early final glacial most between 65,000 and 37,000 years in the past, earlier than the worldwide final glacial most.

Altiplano-Puna magmatic physique. The shallow conductors appear to relate to local volcanoes such as the Laguna Colorada vent but in addition Uturuncu; the latter conductor lies at 2-6 kilometres (1.2-3.7 mi) depth, is less than 10 kilometres (6.2 mi) wide, and should encompass molten rock with saline aqueous fluids. There could also be a shallow magma chamber under the volcano at 1-3 kilometres (0.62-1.86 mi) beneath sea stage. Uturuncu has formed about a hundred kilometres (sixty two mi) east of the primary volcanic entrance within the Western Cordillera, in a terrain formed by numerous volcanic and sedimentary rocks of Miocene-to-Quaternary age.

The Atana (four Ma) and Pastos Grandes (3 Ma) ignimbrites are different giant ignimbrites in the realm whereas the San Antonio ignimbrite (10.33 ± 0.64 Ma) is more sparse. Many of them formed alongside northwest-southeast trending lineaments such because the Lipez-Coranzuli and vapediy Pastos Grandes-Cojina lineament that passes through Uturuncu. Volcanic Explosivity Indices of 8 at Cerro Guacha, La Pacana, Pastos Grandes, and vapepresident Vilama. Other volcanoes, from east counterclockwise to west, are the Cerro Panizos caldera, Cerro Lípez, Suni K'ira, and Quetena volcanoes in addition to many extra minor volcanic centres.

There may be little info on local climatology, however mean annual precipitation is about 100-200 millimetres per year (3.9-7.9 in/yr) or even less than that, most of it originating within the Amazon basin to the east and falling during December, vapediy January, and February. Annual temperatures within the region range between 0 and 5 °C (32 and 41 °F), vapezigaretten and in 1963, the snowline was reported to exceed 5,900 metres (19,400 ft) elevation.

Earthquakes are lacking from the depth range of the Altiplano-Puna magmatic body but occur under it, implying that it is underlaid by brittle, cold crust. 60 earthquakes happen a number of occasions per month. The intensities of the earthquakes attain magnitude ML3.7. 15 kilometres (9.3 mi) and that includes levees, circulate ridges, and steep, blocky fronts over 10 metres (33 ft) thick.
