Chaxas (volcano)

Coordinates: 22°45′S 68°00′W / 22.750°S 68.000°W / -22.750; -68.000[1] Chaxas is a lava dome complex which has been the source of the 1.09±0.56 mya Chaxas ignimbrite in the Andes. The ignimbrite dips away from the domes and are partially younger than the Puripicar ignimbrite.[2][1] The dome has a diametre of 5 kilometres (3.1 mi) and fills the vent area of the ignimbrite.[3] Licancabur volcano is constructed on top of this ignimbrite.[4] Some Inka ceramics are derived from the clay in this ignimbrite.[5]
