Abstract

The main stratigraphic and tectosedimentary features of the Lower Cretaceous in the Jumilla-Yecla area, Murcia and Albacete regions, are presented and analyzed. The outcrops belong to the Prebetic Zone of the External Betic chains. Two sedimentary domains, the Albacete and the Prebetic (s.s.) domains, are differentiated taking into account the stratigraphic architecture of the Cretaceous rocks, mainly the occurring hiatuses and the relation with the underlying Jurassic rocks. The characteristics of the five depositional sequence sets distinguished in the Lower Cretaceous and the tectonics of the area, in which sierras and valleys alternate, are presented. Finally, the tectosedimentary evolution of the region, with different stages of extensional tectonics and faultblock rotation affecting the Prebetic and, later, the Albacete domains, is resumed.
