Шаблон:Short descriptionШаблон:Distinguish Шаблон:Infobox rockunit The Divisadero Group is a group of geological formations in the Magallanes Basin (Chile) or Austral Basin (Argentina) of northwestern Patagonia. It overlies the Coihaique Group.[1] The group is chiefly made up of pyroclastic rocks and lavas of the calc-alkaline magma series.[1] Rocks are of andesite and rhyolite composition.[2]

Geographic extent

In Chile, the formation crops out in Aysén Region[1] while in Argentina it can be found in Chubut Province.[2]

Tectonic movements during the Miocene have significantly deformed Divisadero Group.[3]
