Devonian metavolcanic rocks in the Rio Puelo section, Patagonian Andes of Chile: possible implications for the eastern limit of Chaitenia and the origin of the Liquiñe Ofqui Fault Zone

Key Points

• The findings indicate a complex geological history of metavolcanic rocks in the Devonian period.
• Geological mapping of the Rio Puelo section uncovers key features of the Liquiñe Ofqui Fault Zone.
• Analysis of rock samples reveals insights about the tectonic evolution of the region.
• Understanding Chaitenia's extent may reshape interpretations of Andean geological history.
