Kari-Kari (caldera)
Kari-Kari is a Miocene caldera in the Potosi department, Bolivia. It is part of the El Fraile ignimbrite field of the Central Volcanic Zone of the Andes. Volcanic activity in the Central Volcanic Zone has generated 44 volcanic centres with postglacial activity and a number of calderas, including the Altiplano-Puna volcanic complex.
Kari-Kari is a caldera whose dimensions are variously considered to be or . After emplacement of the caldera, intrusive activity generated the Kari-Kari dome which was originally considered to be a batholith. Mineralization reactions have formed a number of mineral deposits at Cerro Rico and inside the caldera.
