Nevado San Francisco, or Cerro San Francisco (Spanish pronunciation: [neˈβaðo/ˈsero saɱ fɾanˈsisko]), is a stratovolcano on the border between Argentina and Chile, [3] located just southeast of San Francisco Pass. It is considered extinct and is one of the several 6,000 m (19,700 ft) peaks in the area, of which the chief is the Ojos del Salado. It is on the border of 2 provinces: Argentinean province of Catamarca; Chilean province of Copiapo. [4] [5] [6]
The volcano is part of the Central Volcanic Zone of the Andes [7] and reaches an elevation of 6,016 metres (19,738 ft). [8] [4] [a] [b] It is composed from andesite with the exception of basaltic cones and lava flows on the eastern side. These cones are part of the Peinado lineament and a sample was dated 200,000 years ago by argon chronology. [15]: 74–75 They are noteworthy for their olivine phenocrysts. [7] One lava flow less than one million years old reaches a length of 11 kilometres (6.8 mi). [16] The western slopes contain dacitic lava domes. [17] On the summit lie two circle-shaped constructs, of Inca or Formative period ages. [15] San Francisco was first climbed by Walther Penck (Germany) on 16 December 1913. [18]
