The mountain and its surrounding form part of the Aconcagua National Park. It shares borders with Chile, Paraguay, Brazil, Uruguay, and South Atlantic Ocean. The mountain was named after a French geologist, Pedro Jose Amedeo Pissis. It is the world’s highest active volcano at an elevation of 22,615 feet above the sea level. [16] Additional ages were obtained on the main edifice, 1.57 ± 0.1 million years ago, 1.14 ± 0.37 million years ago, and 1.00 ± 0.13 million years ago. [2] Even the crater does not support the development of glaciers.

The mountain and the surrounding area is home to diverse flora and fauna species. Simultaneously, the back-arc experienced increased volcanic activity. [14] It has been suggested that a perpendicular chain of volcanoes including Ojos del Salado may be the consequence of the Juan Fernandez Ridge subducting in the Peru-Chile Trench. [18] With a height of 6,621 metres (21,722 ft), Incahuasi is the 12th-highest mountain in South America[19] and one of the world's highest volcanoes. Aconcagua is the highest mountain located outside of Asia, and the highest peak in both the Southern and Western Hemispheres. Between 9 and 6 million years ago, volcanic activity in the Maricunga Belt decreased and eventually ceased. [25] Lava flows on the main stratovolcano are dacitic. [12], The area is dominated by volcanoes that were active after 1.5 million years ago.

However, there are some border disputes, particularly around the Southern Patagonian Ice Field. [24] This aridity is caused by the rain shadow effect of the Subandean Ranges, which block moisture from the Atlantic Ocean. [36], This article is about the volcano on the border between Argentina and Chile. [22] Two 2-kilometre-long (1.2 mi) coulees extend north and east of the main crater. Monte Pissis also has dry conditions due to its location in the Atacama Desert. Countries Where Illegal Wildlife Trade Is A Major Threat To Wildlife. Argentina has a mainland surface area of almost 2.8 million square kilometers, making it the world’s eighth largest country and Latin America’s second largest. [15], Geological evidence suggests that volcanism in the area dates back to the Oligocene and Miocene, when the main volcanic arc was located 40 kilometres (25 mi) west in the Maricunga Belt. Ojos del Salado experiences dry conditions due to its location near the Atacama Desert. The northern end of the border is a tripoint it forms with those at the Argentina–Bolivia border and the Bolivia-Chile border in Atacama desert. [6] The mantle itself had been modified before by crustal material added by delamination of the lower crust and subduction erosion. It is an extinct volcano located north of Aconcagua in La Rioja Province. Background. One of the outstanding geographical features of Argentina is the mountains. On 16 December 1998, an agreement between Argentina and Chile was signed to set the border line from Mount Fitz Roy and Mount Daudet and finish with the historical dispute. Argentina declared its independence in 1816 and Chile did the same in 1818. [7], Incahuasi is part of the Central Volcanic Zone of the Andes, together with about 110 other Quaternary volcanoes, and lies in the southern sector of this zone;[8] other volcanic zones in the Andes are the Northern Volcanic Zone, the Southern Volcanic Zone, and the Austral Volcanic Zone. [30] Based on their preservations, the lava flows appear to be of roughly comparable ages. [13] Also located close to Incahuasi are Falso Azufre and Nevado San Francisco,[6] as well as the Miocene Cerro Morocho and Cerro Ojo de Las Lozas volcanoes.

The Argentina–Chile border is the longest international border of South America and the third longest in the world after the Canada–United States border and the Kazakhstan–Russia border. In colonial times, products were transported by mule from one side of the Andes to the other. [14] Subsidiary vents conversely are associated with fissure vents. How Much Of The Amazon Rainforest Is Left? [16] The volcano has a volume of about 231 cubic kilometres (55 cu mi)[17] and covers a surface area of about 207 square kilometres (80 sq mi).
