The Cañizar Sandstones (Early Triassic) of the SE Iberian Ranges display several distinct braided stream facies, including channels, bars and sandflats. Nine individual facies and three main facies associations have been defined and their three-dimensional architecture related to auto- and allocyclic processes.
The Cañizar Sandstones were deposited in a narrow semigraben or highly asymmetric graben (the Iberian Basin) trending NW–SE in what is now central Spain, by a fluvial system flowing SE towards the Tethys Sea.
Six major intervals separated by bounding surfaces have been recognized in the area, and are believed to be caused by spasmodic activity of the SW boundary fault system.
