RT Journal Article T1 Estudio preliminar sobre la tectónica sinsedimentaria del Cretácico inferior en el borde septentrional de la Cubeta de Aliaga (Cordillera Ibérica) T1 Preliminary study of the Lower Cretaceous synsedimentary tectonics in the northern border of Aliaga sub-basin (Iberian Chain) A1 Liesa, Carlos L. A1 Soria, Ana Rosa A1 Meléndez Hevia, Alfonso AB The Aliaga sub-basin was developed during the Early Cretaceous in an extensional context. Structures near the northern border of this sub-basin (normal faults, syntectonic unconformities and facies and thickness changes in the basin infill) are related to this extensional tectonics. The graben and semigraben system determines the syntectonic infill thickness. In the footwall of the main faults the pre-rift sequence is eroded PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/13201 UL http://hdl.handle.net/10272/13201 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
