Resumen

The Apeleg Formation is a Lower Cretaceous marine succession of the Aisen Basin of southern Chile. Clastic sediments were deposited in a shallow epicontinental sea in a north-south elongated retroarc basin. This sedimentary basin developed as a thermal sag to the east of a subduction-related magmatic arc on the South American continental margin. A sequence of up to 1200 m of well-sorted sandstones and mudstones are characterised by mud-draped ripples and a well-preserved and varied trace fossil assemblage. The sediments were deposited as offshore tidal sandbars or sand ridges on a shallow marine shelf.
