Pali-Aike Volcanic Field
Coordinates: 52°04′55″S 69°41′53″W / 52.082°S 69.698°W Pali-Aike volcanic field is a volcanic field in Argentina which straddles the border with Chile. It is part of a province of back-arc volcanoes in Patagonia, which formed from processes involving the collision of the Chile Rise with the Peru–Chile Trench. It lies farther east than the Austral Volcanic Zone, the volcanic arc which forms the Andean Volcanic Belt at this latitude.
Pali-Aike formed over a Jurassic basin starting from the late Miocene as a consequence to regional tectonic events and local extension. It consists of an older plateau basalt formation and younger volcanic centres in the form of pyroclastic cones, scoria cones, maars and associated lava flows. These vents often form local alignments along lineaments or faults. The volcanic field is noteworthy for the presence of large amounts of xenoliths in its rocks and because the maar Laguna Potrok Aike is located here.
