Abstract

Facies types and depositional models for thick gravity-flow deposits are inferred from Cretaceous Pyrenean examples occurring in different sedimentary settings: basin-plain during relative low sea level stand; slope-apron or deep valleys during relative sea level rise; and slope during relative sea level rise. The depositional units are interpreted as debrites, debrite-turbidite couplets, and megaturbidites. They are a function of transport distance and hydraulic jump by liquefaction and phase separation in large subaqueous flows.
