This breccia was originated during a tectonic extension at the onset of the Jurassic by a number of procceses, including: (1) the erosion of the underlying Triassic units; (2) the tectonic breakage of a shallow carbonate platform developed coevally to the tectonic extension. The main contribution of this paper is the finding and description of a lower Liassic carbonate platform, which is preserved on its original positionspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Sedimentary brecciaExtensional basinIberian basinJurassicjournal articleopen access
