Laguna del Maule (volcano) about fourteen shield volcanoes and stratovolcanoes that have been degraded by glaciation. The Laguna del Maule volcanic field covers a surface area of and contains cones, lava domes, lava flows, and shield volcanoes. There are 130 volcanic vents at Laguna del Maule. The lake is surrounded by 36 silicic coulees and lava domes. Over of the field is covered by these rocks, and volcanic ash and pumice produced by the eruptions has been found in Argentina. Presently some summits around Laguna del Maule reach altitudes of . The volcanic field lies at an average height of . Among the various
Laguna del Maule (volcano) have been compared to the ones of Tronador volcano; additional compositional similarity is found to other volcanoes close to Laguna del Maule such as Cerro Azul and Calabozos. Laguna del Maule stands out for the frequency of rhyolitic rocks, compared to volcanoes farther south in the chain. There are compositional trends in the region of the volcanic arc between 33°-42°, with more northerly volcanoes being more andesitic in composition while to the south basalts are more frequent. All the postglacial activity appears to originate from a shallow silicic magma chamber beneath the caldera, which acts as a trap for mafic
