Tilocalar are two volcanoes in the Central Volcanic Zone of the Andes. They are constructed on Pleistocene ignimbrites and are 3.5 kilometres (2.2 mi) afar. Tilocálar Sur (23°58′36″S 68°7′30″W) is a 3,116 metres (10,223 ft) high polygenetic volcano and has an explosion crater one kilometre to the south. Two other craters are also present along a graben. Four basaltic andesite-andesite lava flows emanate from it. Tilocálar Norte (23°55′42″S 68°6′18″W) is a 3,040 metres (9,970 ft) high monogenetic system and generated northbound lava flows that run along the eastern wall of the Callejón de Tilocálar. Based on the age of the underlying Tucucaro ignimbrite (3.2 mya) the volcano is less than 3.2 million years old. An andesitic dyke swarm is associated with this system.
