The Mesozoic and Cenozoic of the Malaguide Complex in the Malaga area: a Paleogene olistostrome-type chaotic complex (Betic Cordillera, Spain)

Abstract

This paper analyses the stratigraphic disorganization of the Mesozoic and Cenozoic in the Malaguide Complex of the Málaga area and concludes that this disorganization was caused by gravitational tectonics, which arranged most of the Meso-Cenozoic in olistostrome-type chaotic masses. The deformations occurred between the Middle Eocene and the latest Oligocene. The paper also reports the presence of up to now partially unknown Eocene sediments, deposited in lagoonal environments. Finally, for the first time, the existence around Málaga of sediments belonging to the Upper Oligocene - Aquitanian Ciudad Granada Group and the Lower Burdigalian Viñuela Group is shown.
