In this study, we present new sedimentological and micropaleontological data from the post-evaporitic deposits of the Feos Formation. We worked in two sections (Barranco de los Castellones and Gafares) of the central area of the Neogene basin of Níjar, SE Spain. This formation has traditionally been associated with “Lago-Mare” facies, deposited after the Messinian Salinity Crisis (MSC) and described in various locations around the Mediterranean.
We described a new biofacies with abundant Paratethys ostracods in the deposits of the Feos Formation in the Barranco de los Castellones (BDC) section that we called oxidized horizon (oh). Additionally, we propose two different correlations between the two sections, BDC and Gafares (GAF). Although there are still unresolved issues, this work provides relevant information that should be included in future discussions when formulating hypotheses for the Mediterranean’s evolution after the MSC.
