Volcán Linzor is a stratovolcano on the border between Bolivia and Chile. In its vicinity lie Laguna Colorada and Cerro del León.
Since the late Oligocene, subduction of the Nazca Plate beneath the South America Plate has caused volcanism on the western edge of South America, including the formation of the Central Volcanic Zone. The crust in the Central Andes contains both an upper felsic layer and a lower mafic layer and was partly assembled from numerous terranes during the Mesoproterozoic. The most important two form the Arequipa-Antofalla crustal domain.
Linzor volcano is part of the Central Volcanic Zone. The Andean Central Volcanic Zone has erupted large ignimbrites and lava flows. Dominant rocks are andesite and dacite. One part of the Central Volcanic Zone is the Altiplano-Puna volcanic complex, a system of ignimbrite sheets and lava domes that was active between 8.4 and 2.9 million years ago and is underpinned by a layer of partially molten crust. In the Linzor area, volcanism is represented by the 8.3 million years old Sifon ignimbrite, Cerro Chillahuita and Cerro Chao.
