Cerro Tuzgle (Spanish pronunciation: [ˈse.ro ˈtus.ɡle]) is a dormant stratovolcano in the Susques Department of Jujuy Province in northwestern Argentina. Tuzgle is a prominent volcano of the back arc of the Andes and lies about 280 kilometres (170 mi) east of the main volcanic arc. Part of the Central Volcanic Zone of the Andes, its summit is 5,486 metres (17,999 ft) above sea level and it grew during different stages over a caldera and lava domes. Some major lava flows emanate from the summit crater, and one confirmed and one possible flank collapse unit as well as an ignimbrite sheet are associated with Tuzgle.
The first volcanic activity at Tuzgle occurred 650,000 years ago and formed the Tuzgle Ignimbrite. Subsequently, lava domes and several lava flows were erupted; scientists have proposed two different schemes of naming the units. The most recent lava flows are dated at 300,000 years ago and volcanic activity may have continued into the Holocene.[a] Several thermal springs are associated with the volcano, and some have been investigated for possible geothermal energy production. Sulfur was formerly mined on the mountain.
