RT Journal Article T1 El Aptiense de Lanestosa (Bizkaia): implicaciones paleotectónicas T1 The Aptian of Lanestosa (Bizkaia): palaeotectonic implications A1 López Horgue, Mikel A. A1 Fernández Mendiola, Pedro Ángel A1 García Mondéjar, Joaquín AB The Aptian of Lanestosa is analyzed based on detailed mapping and facies analysis. Four sedimentary units are differentiated: a basal terrigenous unit and three overlying carbonate platform units. Units boundaries 2-3 and 3-4 represent unconformity surfaces linked to synsedimentary tectonic activity. The Cabuerniga-Ramales E-W trending fault is responsible of the repeated block tilting in mid Aptian and late Aptian times. The origin of Pb-Zn ores in this area is likely related to this tectonic activity PB Sociedad Geológica de España YR 1997 FD 1997 LK http://hdl.handle.net/10272/10288 UL http://hdl.handle.net/10272/10288 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
