RT Journal Article T1 Caracterización geoquímica y tectonomagmática de los haces de diques básicos del extremo oriental de la Zona Sudportuguesa T1 Geochemical and tectonomagmatic characteristics of the basic dykes swarms of the Eastern South Portuguese Zone A1 García Navarro, Encarnación A1 Rosa Díaz, Jesús de la A1 Fernández Rodríguez, Carlos A1 Castro Dorado, Antonio AB High volumes of diabase dykes outcrop in the Eastern part of the South Portuguese Zone, which crosscutting the subvolcanic and plutonic rocks of the Seville Range batholith (SRB), and they are covered by permian deposits of the Viar Basin. Geochemically, the diabases were originated in a tectonic setting similar to basic rocks of the SRB, therefore both have been derived from the same matelic source in a tectonic setting of active margin PB Sociedad Geológica de España YR 2002 FD 2002 LK http://hdl.handle.net/10272/9095 UL http://hdl.handle.net/10272/9095 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
