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) Probably due to increased convergence rates of the Nazca and South America plates for the past 28 million years, a phase of strong volcanic activity commenced in the Andes 25 million years ago. It is likely that this phase persisted without interruption until today. In the area of Laguna del Maule, the subducting Nazca plate reaches a depth of and is 37 million years old there. During the Late Miocene, the convergence rate was higher than today and the Malargüe fold belt formed east of the main chain in response. The Moho is found at depths of beneath the volcanic
