A model of lacustrine sedimentation for the Early Pleistocene deposits of Guadix-Baza basin (southeast Spain)

The Early Pleistocene deposits of Guadix-Baza basin represent a depositional unit with distinctive features in the tectosedimentary history of this intramontane basin, which sedimentary infillings range in age between the uppermost Miocene and 45 ka. This Pleistocene unit has an average thickness of 10 m and is composed of carbonate lacustrine facies arranged in an upward-shallowing sequence. The paleontological richness of this unit is evidenced by its special sedimentological and paleoecological features. Diverse numerical analytic data related with the evolution of the sedimentary sequences and the establishment of the sedimentary and paleoecological scenario are presented.
