The Cenozoic Malaguide Basin from Sierra Espu\u00f1a (Internal Betic Zone, S Spain) due to the\u00a0quality of outcropping, areal representation, and continuity in the sedimentation can be considered\u00a0a key-basin. In the last 30 years, a large number of studies with very different methodological\u00a0approaches have been done in the area. Models indicate an evolution from passive margin to wedgetop\u00a0basin from Late Cretaceous to Early Miocene. Sedimentation changes from limestone platforms\u00a0with scarce terrigenous inputs, during the Paleocene to Early Oligocene, to the deep basin with huge\u00a0supplies of turbidite sandstones and conglomerates during the Late Oligocene to Early Miocene.\u00a0The area now appears structured as an antiformal stack with evidence of synsedimentary tectonics.\u00a0The Cenozoic tectono-sedimentary basin evolution is related to three phases: (1) flexural tectonics\u00a0during most of the Paleogene times to create the basin; (2) fault and fold compartmentation of the\u00a0basin with the creation of structural highs and subsiding areas related to blind-fault-propagation\u00a0folds, deforming the basin from south to north during Late Oligocene to Early Aquitanian times;\u00a0(3) thin-skin thrusting tectonics when the basin began to be eroded during the Late Aquitanian-Burdigalian. In recent times some works on the geological heritage of the area have been performed\u00a0trying to diffuse different geological aspects of the sector to the general public. A review of the\u00a0studies performed and the revisiting of the area allow proposing different key-outcrops to follow the\u00a0tectono-sedimentary evolution of the Cenozoic basin from this area. Eight sites of geological interest\u00a0have been selected (Cretaceous-Cenozoic boundary, Paleocene Mula Fm, Lower Eocene Espu\u00f1a-\u00a0Valdelaparra Fms, Middle Eocene Malvariche-C\u00e1novas Fms, Lowermost Oligocene As Fm, Upper\u00a0Oligocene-Lower Aquitanian Bosque Fm, Upper Oligocene-Aquitanian R\u00edo Pliego Fm, Burdigalian\u00a0El Ni\u00f1o Fm) and an evaluation has been performed to obtain four parameters: the scientific value,\u00a0the educational and touristic potential, and the degradation risk. The firsts three parameters obtained\u00a0values above 50 being considered of \u201chigh\u201d or \u201cvery high\u201d interest (\u201cvery high\u201d in most of the\u00a0cases). The last parameter shows always values below 50 indicating a \u201cmoderate\u201d or \u201clow\u201d risk of\u00a0degradation. The obtained values allow us considering the tectono-sedimentary evolution of this\u00a0basin worthy of being proposed as a geological heritage.<\/p>\n
