| Sumario: | The Dogger-Malm boundary unconformities show different structures in the Eastern Subbetic outcrops. They are identified by the presence of characteristic fossils associated to the hardgrounds, two types of ichnofossils (Thalassinoides and litophagine borings), stromatolites, and neptunian dykes and a paleofault. They were generated in pelagic swells with changes in the intensitiy of oceanic currents. The hiatuses associated to these unconformities are variable between differents outcrops, mainly including the Upper Bathonian and the Upper Callovian-Lower Oxfordian |
