RT Journal Article T1 Análisis de modelados de erosión y depósitos residuales transgresivos en el Sector Central de la Cuenca del Guadalquivir (Tortoniense, SO de España) T1 Analysis of erosive modelated and transgressive lag deposits in the Central Sector of the Guadalquivir Basin(Tortonian, SW Spain) A1 Abad de los Santos, Manuel A1 Ruiz Muñoz, Francisco A1 Cantano Martín, Mercedes A1 Rodríguez Vidal, Joaquín A1 Pendón Martín, José Gabriel A1 González-Regalado Montero, María Luz A1 Mantero Romero, Elena María A1 Cáceres Puro, Luis Miguel AB The central sector of the northern foreland margin of the Guadalquivir Basin shows good examples oftransgressive erosion surfaces, recognisable along all its extension. In the studied area (Villanueva del Rio yMinas, Sevilla) theses surfaces allow us to identify different erosion levels and various morphological structureslinked to such surfaces. According to: i) the transgressive deposits related to these relieves, ii) the types ofmaterials that these surfaces have associated (sediments or substratum) and, iii) its topographic elevation,we can link these geomorphologic structures (“plataformas”, “mesas” y “cuestas”) to a transgressedsedimentary environment, such as a rocky shoreline or a sandy-gravel beach. Other data such as theerosive agent (wave) that generated theses surfaces or the situation of the shoreline during Tortonian canbe inferred PB Sociedad Geológica de España YR 2004 FD 2004 LK http://hdl.handle.net/10272/8814 UL http://hdl.handle.net/10272/8814 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
