The Nuevo Mundo (also: Jatun Mundo Khori Huarani ) is a stratovolcano in the Andes -Hochland the South American landlocked country like Bolivia .
location
The Nuevo Mundo volcano is a volcanic cone on the edge of the Cordillera de Lípez in the Potosí department in the central Altiplano region between the cities of Potosí and Uyuni . At a height of 5,438 m, it rises around 700 meters from the Los Frailes Plateau.
Discovery story
The first mountain ascent in the region took place by the French Georges Courty before 1903, whose notes can be found in the 1987 book "Mountaineering in the Andes" by Jill Neate: “Nuevo Mundo, 6020 m, position unknown.”
The German geologist Friedrich Ahlfeld , an avid mountaineer, moved to Bolivia in 1924 and after the Second World War began exploring the mountain peaks in the Department of Potosí, some of which he also climbed. In a letter from 1962 to the historian Evelio Echevita, he mentioned that two peaks of the Cordillera de Lípez could be considered "Nuevo Mundo" in relation to the altitude mentioned by Georges Courty .
In 1969, however, in his book "Geografia Fisica de Bolivia" , Ahlfeld presented the Nuevo Mundo with a height of 5438 meters in a drawing and described its location southwest of Potosí directly north of the village of Potoco , so far from the Cordillera de Lípez.
In the late 1990s, Toto Aramayo, Yossi Brain and Dakin Cook went in search of the Nuevo Mundo and located it at 19 ° 47'0 "south latitude and 66 ° 29'0" west longitude. The Bolivian government and the USGS now recognize this as the correct location of Nuevo Mundo, although some more recent maps still refer to Cerro Lípez as Nuevo Mundo.
geology
The volcanic cone of Nuevo Mundo today consists mainly of ash and pumice stone. At the base there were two leaks of lava in prehistoric times along a north-south running fault line, apparently simultaneously with rock and ash ejecting in an easterly direction. A highly explosive Plinian eruption dates back to a later time , the ash rain carried more than 200 km to the east to the region of today's Potosí - an eruption that occurred before the arrival of the Spaniards (1533), but in historical times got to. Because while earlier eruptions of the Kari-Kari Caldera, Cerro Wila Kkolu, Cerro Condor Nasa, Cerro Villacolo and Cerro Huanapa Pampa had formed the Los Frailes plateau, the plateau was made of mighty ignimbrite by the last eruption of the Nuevo Mundo in the Holocene - Covered layers, which mainly consist of pyroclastic material, dacite and andesite .
