Escucha Formation (Spain)

The Escucha Formation is a geological formation in La Rioja and Teruel provinces of northeastern Spain whose strata date back to the late Aptian to middle Albian stages of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.[1]

The approximately 70 m (230 ft) thick formation underlies the Utrillas Formation and overlies Castrillo de la Reina, Benassal & Oliete Formations. The Escucha Formation comprises siltstones, mudstones, sandstones, coal, siltstones and amber, in which diverse fossil insects were found. The formation was deposited in a variety of continental to paralic (deltaic) environments.[2]

Depositional Environment

[edit]

The Escucha Formation represents syn-rift depositional environment, deposited in siliciclastic carbonate platforms, coastal siliciclastic environments and other offshore settings. In the basal part of the formation, cobble to boulder-sized dropstones of glacial origin have been identified, representing long-distance iceberg rafting from Arctic sources.[3]
