RT Journal Article T1 Extensión versus compresión durante el Mioceno superior en la Cuenca de Lorca (Báticas orientales) T1 Extension versus contraction during the Upper Miocene in the Lorca basin (eastern Betics) A1 Booth Rea, G. A1 Azañón, José Miguel AB Structural and paleostress analysis of the Tortonian sedimentary cover of the Lorca basin (eastern Betics), shows the existence of alternating extensional and convergent tectonics during this period. With ENE/ WSW-oriented Tortonian folds being cut and tilted by upper Tortonian normal faults with NW/SE to SW/ NE tectonic transport, which define a paleostress tensor indicative of radial-extension. These faults were later folded during further uppermost-Tortonian to Messinian convergence PB Sociedad Geológica de España YR 2003 FD 2003 LK http://hdl.handle.net/10272/9048 UL http://hdl.handle.net/10272/9048 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
