Aguilas Arc Basin:Cyclically-arranged calcilutites and sandstones (Early Pliocene) in the Piedra Mala beach. These marine deposits rest on the Betic basement (iron mineralized breccias), and mark the reflooding after the late Messinian desiccation of the Mediterranean
Baza Basin: Pliocene – Pleistocene lacustrine carbonates cut by the Barranco León ravine (Orce sector). The Barranco León paleontologic site (at the left of the image) contains the oldest human fossils of Europe. The age of this site is calculated close to 1.4 Ma (millions of years ago)
Bajo Segura Basin: Late Tortonian, shallow marine sandstones (vertical strata) cropping-out near Crevillente (north sector of the Bajo Segura Basin). This deformation is related to the activity of the left-lateral Crevillente fault zone
Campo Coy Basin: Late Tortonian, shallow water evaporites (thin bedded alternation of gypsum and marls) as the record of the marine restriction of the Betic Corridor well before the Messinian Salinity Crisis
Fortuna Basin: Late Tortonian marine marls (the Sanel Marls, in the palm trees outcrop) covered by early Messinian evaporites (the so called Chicamo Cycles).  Like to others neighboring basins (i.e. Campo Coy and Lorca) these evaporites are related to an early marine restriction phase prior to the Messinian Salinity Crisis
Guadalentin Basin: Tortonian marine marls cropping-out in the Gebas water reservoir. These deposits represent the maximum extent of the marine seaway between the Atlantic and Mediterranean through the Betic Cordillera
Granada Basin: Tortonian bryozoans-rich sandstones forming the basal marine deposits of the Granada basin (Alhama de Granada sector). Cross-bedded units are related to tidal activity  in a marine seaway (Betic Corridor) between the Atlantic and Mediterranean domains
Guadalquivir Basin: Early Tortonian deep marine marls (intensively cultivated with olive trees) in the Sabiote sector. At the background of the image, the outcrops correspond to the basement (Triassic Red Beds, or “Tabular Cover”) of the Guadalquivir foreland basin
Guadix Basin: Late Tortonian marine units in the northern end of the Guadix Basin (La Lancha sector). Shallow marine calcarenites (including coral reefs) lie on a thick succession of deep marine marls. The boundary between these two units marks the restriction and definitive closure of the Betic Corridor. No marine Messinian deposits appear over the shallow marine unit
Lorca Basin: Late Tortonian sapropels and diatomites (showing cyclic arrangement) capped by evaporites in the La Serrata sector. The evaporit unit of the Lorca Basin(dominated by laminar gypsum) represents the extreme marine restriction of the basin
Mazarron Basin: Epithermal ore deposits(Pb-Zn-Ag) associated to the late Miocene volcanic activityin the mining district of Mazarrón
Nijar Basin: Early Pliocene fine-grained marine calcarenites near the Argamasón village. The lowest stratigraphic terms (white beds at the rigth of the image) correspond tho the so-called Feos Formation (late Messinian Lago Mare unit). The boundary between these two units corresponds to the Pliocene transgression, marking the end of the Messinian Salinity Crisis
Sorbas Basin: Pre-evaporitic, precessional Messinian cycles (sapropels/homogeneous marls + diatomites) in the Abad Member. Evaporites (selenitic gypsum) of the Yesares Member are visible at the upper-left corner of the image.
Ronda Basin: Deeply incised Late Miocene conglomerates (fan delta deposits) at the El Tajo (cliff) de Ronda
Vera Basin: Panoramic view of the classical Cuevas del Almanzora section, where the Messinian – Pliocene boundary is exposed. Gently leftward dipping Messinian marls (yellow house) are covered by Early Pliocene silty marls with sandtone layers (ruined cave houses).  A thin conglomerate layer separating both units defined the Messinian – Pliocene discontinuity
