La ruptura de la plataforma carbonatada Iiásica en la Unidad de Jabalcuz (dominio intermedio, prov. de Jaén)

Abstract

The break-up of the lower Liassic carbonate platform (Fm Gavilán) in the Jabalcuz area records a variety of sedimentary models of this event. Two fracture phases related to the genesis of the Fm GavUán-top unconformity have been recognized. These fracture phases and sea-level fluctuations were responsible for the differentiation of areas where, 1) condensed levels on relative submarine highs, 2) fault-related carbonate clastic wedges, and 3) paleokarst and related features on relatively more elevated and temporary emerged areas, were deposited. The presence of all this sedimentary models in a same laterally continuous outcrop, is really exceptional in the whole Betic External Zones
