Zapaleri is a volcano whose summit is the tripoint of the borders of Argentina, Bolivia and Chile. A number of railways are in the area. The volcano formed on top of the 2.89 mya Tara Ignimbrite from the Guacha caldera and the basement beneath the volcano is formed from Cretaceous and Tertiary rocks affected by tectonic deformation. Volcanic rocks are andesite, basalt, dacite and rhyolite. Late Cretaceous rocks are also found in the area, as are Pleistocene shoshonite volcanic rocks.
