Lower Paleocene Microcodium -rich calcarenites in hemipelagic areas of the Subbetic Zone, SE Spain: Sr isotopes, source area and palaeogeographic implications

The Danian−early Selandian Olivares and Majalcorón formations are two calcarenite units rich in Microcodium remains that were accumulated in a marine hemipelagic setting of the Subbetic Zone (Betic Cordillera, southern Spain). Their outcrops are restricted to relatively small areas surrounded by upl...
