RT Journal Article T1 Evolución paleogeógráfica de la Cuenca Ibérica en el Cretácico Superior T1 Palaeogeographic evolution of the Iberian Basin along the Upper Cretaceous A1 Segura, M. A1 García Hidalgo, J. F. A1 Carenas, B. A1 Gil, J. A1 García, A. AB In the Iberian Basin, during Upper Albian - Middle Campanian, several shallow carbonate platforms were developed. These platforms grade landwards, westwards to the Hesperian Massif, to silicidastic, littoral and coastal sediments. Two major depositional megasequences (2nd order) and 12 depositional sequences (3rd order) have been recognized. Detailed paleogeographical maps for the eleven basal depositional sequences are presented in this paper. Temporal ranging of these maps is about 2 My, from Upper Albian (102 My) to Lower Campanian (83 My) PB Sociedad Geológica de España YR 2004 FD 2004 LK http://hdl.handle.net/10272/8937 UL http://hdl.handle.net/10272/8937 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 1 jun 2026
