Background:
The large Pleistocene Diamante caldera formed about 0.45 million years ago during a massive super-plinian (supervolcano) eruption that produced an about 350 cu km rhyolitic ignimbrite. After the formation of the caldera, the cones of Volcán Don Casimiro and Cerro Listado volcanoes grew on the SW rim and SW flank of the caldera.The youngest vent of the complex, Maipo stratovolcano rises about 1900 m above the caldera floor and was constructed by strombolian-vulcanian explosions. It has ashfall deposits that overlie glacial ice.
Several parasitic cones were constructed on the east flank of Maipo along a series on NE-trending fractures. Lava flows from one of these cones blocked drainages in 1826 inside the caldera, forming Lake Diamante on the eastern caldera floor.
