Cerro Panizos is a Miocene-age shield-shaped volcano spanning the Potosí Department of Bolivia and the Jujuy Province of Argentina. It features two calderas, a group of lava domes and part of the Altiplano–Puna volcanic complex (APVC). Cerro Panizos is also part of the Central Volcanic Zone, a volcanic arc that extends from Peru to Chile. Volcanic activity commenced in the APVC about 10 million years ago, producing the large volcanic calderas of Cerro Panizos, Vilama, Cerro Guacha, and the volcano Uturuncu. The formation of the APVC is linked to a giant magmatic body in the crust of the Central Andes. The Cienago Ignimbrite erupted over 350 cubic kilometres (84 cu mi) from Panizos about 7.9 million years ago, and 6.7 million years ago the Panizos Ignimbrite erupted over 650 cubic kilometres (160 cu mi). Volcanic cones were active between the ignimbrite eruptions and a plateau of lava flows and lava domes formed in the central area of the Panizos Ignimbrite after the last eruptions.
