Divisadero Group
The Divisadero Group is a group of geological formations in the Magallanes Basin or Austral Basin of northwestern Patagonia. It overlies the Coihaique Group. The group is chiefly made up of pyroclastic rocks and lavas of the calc-alkaline magma series. Rocks are of andesite and rhyolite composition.In Chile, the formation crops out in Aysén Region while in Argentina it can be found in Chubut Province.
Tectonic movements during the Miocene have significantly deformed Divisadero Group.
