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) San Francisquito, which are both silicic volcanic systems. The activity of Tatara-San Pedro and Laguna del Maule with the presence of rhyolite may be influenced by the subduction of the Mocha Fracture Zone, which projects in the direction of these volcanic centres. Laguna del Maule has erupted basaltic andesite and andesite, with medium content. Dacite and rhyolite are also found. Several silicic rocks are known from the Quaternary. After deglaciation, the composition of Laguna del Maule volcanic rocks has grown more silicic, with andesite eruptions being limited to the edges of the volcanic field since 19,000 years ago. Generally, the
