La cuenca terciaria continental del Diapiro de Murgia: la Formación Izarra (Oligoceno superior-Mioceno inferior, Cuenca Vasco-Cantábrica)

The tertiary continental Izarra Formation (Alava, Basque-Cantabrían Basin) is formally described for the first time. Its materials were deposited on a small basin originated in the central part of the Murgia diapir. Those materials are subdivided in four members which are: a) a basal unit of red mar...

description The tertiary continental Izarra Formation (Alava, Basque-Cantabrían Basin) is formally described for the first time. Its materials were deposited on a small basin originated in the central part of the Murgia diapir. Those materials are subdivided in four members which are: a) a basal unit of red marls and conglomerates formed in diapiric-fringe alluvial systems; b) the intermediate member consists of marls and limestones with paedogenic structures deposited in a temporary inundated outer alluvial plain; c) a top unit with calcareous lutites and fossiliferous limestone concretions (Konservat-Lagerstatten) of lacustrine origin; and d) a calcareous tufa unit overlying the basal member and originated next to hard-water springs whose stratigraphic correlation with the intermediate and top members is not clear.
