{{refimprove|date=November 2018}}{{short description|A distinct fragment of Earth's crust in southern Chile}}Chaitenia is a distinct fragment of Earth's crust in southern Chile. Rocks of Chaitenia represents an ancient island arc that existed next to Patagonia which became eventually accreted to it.^[1] The accretion of Chaitenia to Patagonia occurred in the Devonian period (c. 400-360 million years ago) as inferred from an event where rocks were put under pressure, deformed and heated dated to that period.^[1] After merging into Patagonia, accretionary complexes developed west of it, meaning Chaitenia constituted a backstop.^[1] Chaitenia is not thought to extend beyond the Huincul lineament to the north, beyond which lies the Chilenia terrane.^[1]
