RT Journal Article T1 El surco paleogeográfico de Trucíos-Somorrostro (Albiense Inferior, W. Vizcaya) T1 The Trucíos-Somorrostro sedimentary trough (Lower Albian, N. Spain) A1 García Mondéjar, Joaquín A1 Aranburu Artano, Arantza A1 Rosales, Idoia A1 Fernández Mendiola, Pedro Ángel AB Detailed mapping and facies analysis of onshore Lower Albian sequences in the Trucfos-Somorrostro area led to the establishment of a major paleogeographic trough for the Lower Albian. Listric faulting on the western edge of the trough created a half graben morphology filled with both mass-gravity and traction submarine deposits. Led-zinc ore deposits were emplaced on the karstified calcarenite following the trough fault system PB Sociedad Geológica de España YR 1992 FD 1992 LK http://hdl.handle.net/10272/14121 UL http://hdl.handle.net/10272/14121 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
