Laguna del Maule (volcano) 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 lava flows which surround Laguna del Maule lake. The field gets
Laguna del Maule (volcano) total rock output of over . At least three caldera forming events occurred during the system's lifespan, at 1.5 mya (dacitic Laguna Sin Puerto ignimbrite, the ignimbrite is exposed northwest of Laguna del Maule lake), 950,000 (rhyodacitic Bobadilla caldera, the ignimbrite from this caldera-forming event borders Laguna del Maule lake in the north) and 336,000 years ago generating welded ignimbrites. This last ignimbrite is known as Cordon Constanza ignimbrite. The Bobadilla caldera is centred beneath the northern shore of the Laguna del Maule, and has dimensions of . In total, volcanic output at Laguna del Maule has been estimated to
