The Eocene Jaca basin is a foreland basin with well-exposed carbonate platforms in the distal margin. This margin underwent alternating periods of stable platform growth and platform drowning. Periods of drowning were accompanied by large-scale collapses with generation of shelf-edge truncations and resedimentation of carbonate megabreccias into a terrigenous turbiditic trough. These features caused a stepped retreat of the platforms and are related to episodic variations of tectonic loading in the hinterland and correlative flexural bending of the distal basin.
