- Firmground ichnofacies recording high-frequency marine flooding events (Langhian transgression, Vallès-Penedès Basin, Spain) J.M. de Gibert J.M. Robles Ciencias de la Tierra Miocene Ichnology Spongeliomorpha Sequence stratigraphy The decapod burrow Spongeliomorpha sudolica occurs associated with transgressive firmgrounds in the transitionbetween Aragonian continental red beds and Langhian marine units in some of the inner sectors of theVallès-Penedès Basin. This ichnospecies designates branching burrow systems with scratch marks in the wallsproduced by marine crustacean decapods. The occurrence of Spongeliomorpha represents an example of theGlossifungites ichnofacies. The several horizons where the traces are found are intercalated with continental redbeds a few meters below the main transgressive surface, which is overlain by fossiliferous marine sandstones.The Spongeliomorpha-bioturbated layers record short, high frequency marine flooding surfaces that may berelated either to actual sea-level changes or to variations in tectonic subsidence or sediment input. In any case,these flooding events punctuated the early phases of the Langhian transgression in the basin. 2005 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50530306 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.3 Vol.3
