Stratovolcano in Chile
Tatajachura is a
stratovolcano in
Chile , in the
Isluga National Park .
[2]
During the
Pliocene and
Pleistocene it erupted
lava flows of
andesitic composition
[1] and has a
crater that opens westwards.
[3] The volcano is also the source of the Quebrada de Chiapa valley,
[4] and of an Inca ruin on the summit;
human sacrifices were performed at the mountain to obtain a reliable water supply.
[5]
The age of eruptive activity is unclear; while the appearance of the edifice suggests a lower
Pliocene age, its position in the
Precordillera and atop an older plain suggests it may be older than that.
[6]
Potassium-argon dating has yielded one age, 6 ± 1.3 million years ago.
