Chiliques is a stratovolcano located in the Antofagasta Region of Chile. [1]

Chiliques is capped off by a 500 metres (1,600 ft) wide summit crater, which contains two crater lakes. One of these lakes is found in the northern part and the other east-southeastern part. [2] The volcano is formed by rocks ranging from andesite to dacite; the andesites of the main stratocone building phase contain pyroxene. [3] Together with Tumisa, Leija and Cordón de Puntas Negras it forms a northwest-trending volcano alignment. [4]

The first part of Chiliques to form was a block lava field, which still crops out northeast of the main volcano to a distance of 6.5 kilometres (4.0 mi). Lava flows with lengths of up to 10 kilometres (6.2 mi) then constructed the stratovolcano proper and were later buried by shorter (up to 5 kilometres (3.1 mi)) lava flows that cover a surface of 16.26 square kilometres (6.28 sq mi) around the summit crater. The Cerro Overo maar northeast of Chiliques is occasionally considered the last phase of Chiliques's activity, and the two have erupted rocks with similar chemical composition. [3] There is no evidence for historical activity. [2]

Over years, Chiliques has been monitored from space by ASTER imagery. [5] In 2002, the imagery showed evidence of a temperature anomaly on Chiliques, which occasionally reached a scale of 15 °C (27 °F). This temperature anomaly may reflect either thermal events in crater lakes or fumarolic activity, although evidence for the occurrence of either is equivocal. [5] Some of the anomalies were observed in the crater and others on the upper slopes of the volcano. [2] This anomaly lasted only a few months. [5]

Magnetotelluric investigation of the region has shown evidence of a high-conductivity structure underground between Chiliques, Cordón de Puntas Negras and Láscar. This high conductivity zone reaches a depth of 6 kilometres (3.7 mi) at its southern end, and it might reflect the presence of magma underground. [6]

The lake Laguna Lejia lies north of Chiliques volcano, [7] other parts of the volcano drain into the Salar de Atacama; the volcano forms part of the drainage divide of the salar. [8] A pre-modern route goes up the mountain and aside from the steep slopes and height of the mountain, does not feature any major difficulties. [1]

The town of Socaire is found west of Chiliques, and the volcano has cultural importance to the town, with the volcano being considered the origin of the water for Socaire and part of a cosmological representation together with the neighbouring mountains Tumisa, Lausa, Ipira and Miñiques. [9] Seen from Socaire, the sun rises behind Chiliques during St. Bartholomew's Day; St. Bartholomew is an important saint for the town. [1] Archeological findings made on Chiliques include pottery, a stone room and an elliptical structure in the summit area. Additional platforms and stone structures are found lower on its slopes, and an Incan tambo even farther down. [9] Such archeological sites on mountains are common in Chile, with Licancabur and Cerro Quimal being examples of other mountains with such structures. [1]

Licancabur stratovolcano on the border between Bolivia and Chile

Licancabur is a stratovolcano on the border between Bolivia and Chile, south of the Sairecabur volcano and west of Juriques. Part of the Andean Central Volcanic Zone, it has a prominent, 5,916-metre (19,409 ft)-high cone. A 400-metre (1,300 ft) summit crater containing Licancabur Lake, a crater lake which is among the highest lakes in the world, caps the volcano. Three stages of lava flow emanate from the volcano, which formed on Pleistocene ignimbrites.

Caldera del Atuel is a caldera in Argentina. It is the source of the Rio Atuel and has dimensions of 30 by 45 kilometres. Cerro Sosneado is a volcano located outside of the Atuel caldera, Volcan Overo and Las Lágrimas complex are located within the caldera. Holocene activity may have formed the cinder cones on the northeastern side of the caldera. After the 2010 Maule earthquake, the caldera was one of the volcanic centres that underwent subsidence, along with secondary earthquake activity.

Cerro Overo mountain in Antofagasta Region, Chile; geonames ID = 3877904

Cerro Overo is a maar lying at the foot of Chiliques volcano and close to Laguna Lejía, in the Antofagasta Region of northern Chile over ignimbrites of Miocene-Pliocene age. It is the result of a phreatomagmatic eruption, its maximum diameter is 600 metres (2,000 ft) and its depth is 80 metres (260 ft). The maar formed in postglacial times and erupted basalts that originated in the deep crust, with no magma chamber. The lavas are of lower crustal provenience and are among the least evolved of northern Chile. According to a thesis published in 2017, it formed about 77,000 years ago.

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 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 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 the volcano is less than 3.2 million years old. An andesitic dyke swarm is associated with this system.
