La formación Feos en la cuenca de Carboneras-Níjar: enfoque sedimentológico y micropaleontológico de los depósitos post-evaporíticos del Messiniense
Palabras clave:
Lago-Mare, Horizonte oxidativo, Ostrácodos, Paratethys, Post-evaporitasResumen
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.
