The Guadalentín Depression is the more outstanding landscape feature generated by strike-slip faulting within the central segment of the Eastern Betic Shear Zone (EBSZ).This depression evolved under lacustrine to palustrine (playa-lake) conditions until at least roman times. This work-study paleosols interbedded in the sedimentary sequence of the Espuña Karting profile anddeveloped on calcium carbonate rich fine parent material. Soil morphology and properties from two dated paleosols represent twodifferent environmental crisis, the oldest paleosol from the Bronce Age, developed under conditions that are more humid and indicates a long rupture in sedimentary depression. Roman period paleosol, developed under Mediterranean semiarid conditions, also indicates an important rupture in the depression evolving from palustrine to the present fluvial environment.
