“…1B). The chronostratigraphy of the Baza Formation ranges from the Early Pliocene (Agustí, 1986;Garcés et al, 1996;Piñero and Agustí, 2020) to Middle Pleistocene (Agustí et al, 1987;Agustí et al, 2015b). It is composed of three lithostratigraphic members (Vera et al, 1985;Oms et al, 1998Oms et al, , 2000b: the Lower Member (calcareous surface deposits of a lacustrine and palustrine origin); the Intermediate Member (fluvial mudstones and sandstones); and the Upper Member (lacustrine and palustrine deposits resulting from an accumulation of silty calcareous deposits as well as coarser fractions).…”
