In the Mula Formation of the Eastern Malaguides (Sierra Espuna and neighbouring areas) the early Paleocene (Danian) and the late Paleocene (Selandian and Thanetian) have been dated. These deposits record the transgressive-regressive-transgressive evolution of a mixed siliciclastic-carbonatic platform which received clastic sediments from a carbonate continent with low relief, affected by intense pedogenesis, with a high production of Microcodium and located to the south-east in the malaguide unit of Morron de Totana. There, Garumnian -like continental red deposits fill erosional troughs within the Mesozoic. Upwelling currents rich in inorganic nutrients, coming from deeper zones of the basin, favoured eutrophication of platform areas.Dans la formation Mula des Malaguides orientales (Sierra Espuna et ses alentours), le Paleocene inferieur (Danien) et superieur (Selandien et Thanetien) ont ete dates. Ces depots montrent l'evolution transgressive-regressive-transgressive d'une plate-forme mixte, silicoclastique-carbonatee, qui recevait des apports provenant d'un continent carbonate a faible relief, soumis a une intense pedogenese, a haute production de Microcodium et situe au sud-est, dans l'unite malaguide de Morron de Totana. A cet endroit des depots continentaux rouges a facies de type Garumnien remplissent des depressions d'erosion mesozoiques. Des courants d'upwelling, riches en nutriments inorganiques, arrivant des zones profondes du bassin, ont favorise l'eutrophisation de la plate-forme.
