Laguna del Maule (volcano) Laguna del Maule is a volcanic field in the Andes mountain range of Chile, close to, and partly overlapping, the Chile-Argentina frontier. The bulk of the volcanic field is in the Talca province of Chile's Maule Region. It is a segment of the Southern Volcanic Zone, part of the Andean Volcanic Belt. Many of the volcanic centres in the Laguna del Maule volcanic field formed during postglacial times, after glaciers had retreated from the area. This activity has generated cones, lava domes, lava coulees and
Laguna del Maule (volcano) structures in the volcanic field, Domo del Maule lava dome is of rhyolitic composition and generated a northward flowing lava flow that dammed the Laguna del Maule. This lava flow is joined by other lava flows from the , a small cone in the southwestern sector of the volcanic field; the lavas of this cone however are andesitic and basaltic. is a large long lava flow of acidic rocks in the northern sector of the volcanic field, close to the outlet of Laguna del Maule. This flow contains obsidian and vitrophyre and crystals within the flow reflect the sunlight. The
