Abstract

A stratigraphic section made of Quaternary alluvial–lacustrine sediments belonging to the Baza Formation (South Spain) has been logged and studied for paleomagnetism, rock magnetic cyclostratigraphy, and electron spin resonance (ESR) quartz dating. Our results indicate that the section, which is found in the vicinity of a number of paleontological and archaeological localities, falls within the mid-Early Pleistocene (Calabrian), within the Matuyama Chron, and runs to the Jaramillo Subchron, encompassing the Cobb Mountain Subchron. The magnetostratigraphic results combined with rock magnetic cyclostratigraphy and ESR provide solid timelines, which allow gross accumulation rates to be estimated, and revealing an upsection decrease of sedimentation in accordance with the lithological and paleodepositional changes. Our study furnishes new chronologies to better understand the timing of the latest stages of endorheic sedimentation that precedes the capture of the Baza Basin by the Gualdalquivir River in the Middle Pleistocene.
