RT Journal Article T1 Sucesión de secuencias volcánicas félsicas en el Complejo Vulcanosedimentario de la Faja Pirítica Ibérica: discriminación entre modelos volcánicos y subvolcánicos T1 Succession of felsic volcanic sequences in the Volcano-Sedimentary Complex in the Iberian Pyrite Belt:discrimination between volcanic and subvolcanic models A1 Donaire Romero, Teodosio A1 Pascual Martínez, Emilio A1 Valenzuela Aznar, Alfonso A1 González Roldán, Manuel Jesús A1 Toscano Macías, Manuel AB A field study is presented on two selected areas in the Volcano-Sedimentary Complex (VSC) of the IberianPyrite Belt (IPB), the Odiel River section and the Paymogo Volcanic lineament. Field evidence has allowedto distinguish two major groups of felsic rocks, which successively appear in the stratigraphic column.Probably, this conclusion can be extended to other areas in the IPB. In addition, field, petrographic andgeochemical evidence shows that at least the felsic rhyolitic succession in the Odiel River (and probablyalso in Paymogo) formed in a volcanic, environment, favouring a volcanic-pile model in the VSC PB Sociedad Geológica de España YR 2006 FD 2006 LK http://hdl.handle.net/10272/8635 UL http://hdl.handle.net/10272/8635 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
