Niebla, Guadalquivir Basin (Miocene of Spain)

Where: Spain (37.4° N, 6.7° W: paleocoordinates 37.5° N, 7.4° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Niebla Calcarenite Formation, Tortonian (11.6 - 7.2 Ma)

• The presence of Neogloboquadrina humerosa (Takyanagi & Saito) in the lower part of the Niebla Calcarenite suggests a late Tortonian age (Sierro et al. 1990a). The PF-Event 1 and 2 of Sierro et al. (1993), as well as the Tortonian/ Messinian boundary, were recognised in the overlying GibraleĆ³n Formation at a different location; at Niebla the section immediately above the Calcarenita de Niebla is condensed and the successive GibraleĆ³n Clays show a Messinian age.

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified, shelly/skeletal packstone

• Formed on the inner part of a low gradient homoclinal ramp. Lateral and vertical facies variations are due to the local presence of autochthonous coralline algal and bryozoan patches within areas of bioclastic accumulation, mostly in the form of grain- and rudstones with variable contents of finer matrix.
• calcarenites and calcirudites with varying abundances of fine grained matrix, coralline algae, bryozoans, bivalves (large pectinids and ostreids), echinoids (Clypeaster) and large benthic foraminifera (Heterostegina)

Size classes: macrofossils, mesofossils
