Deltaic Sandstones 

Dynamic stratigraphy, architecture, geometry and facies analysis

This course analyses the facies and quantifies the geometries of sandbodies in depositional environments evolving from continental to slope settings, and studies Permian-Triassic, Cretaceous and Eocene clastic outcrops. Data on Triassic and Eocene deltas comes from mostly unpublished personal research. The Cretaceous delta is based on an update of the paper Depositional Sequence Response to Foreland Deformation in the Upper Cretaceous of the Southern Pyrenees, Spain, by Ardèvol et al., 2000, AAPG Bulletin.
