El drenaje subterráneo de la Sierra de Cameros en la Cuenca del Ebro y su implicación en la génesis de depósitos marginales evaporíticos miocenos

Abstract

In the northern margin of the Cameros Basin miocene evaporitics units are found related with shallow saline lakes. The lakes were fed principal)/ by groundwater loaded with dissolved salts (calcicsulphate waters) from the Lias and Keuper evaporite formations. Durin Miocene, Ebro Basin was a endorheic depression, so the dissolved salts that were carried by groundwater had to precipitate inside the basin; groundwater discharge not be concentrated in a few big springs but it should be distributed in humid areas with evaporitic precipitation
