Chaxas (volcano)

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 diameter 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]
