Sucesión de secuencias volcánicas félsicas en el Complejo Vulcanosedimentario de la Faja Pirítica Ibérica: discriminación entre modelos volcánicos y subvolcánicos

A field study is presented on two selected areas in the Volcano-Sedimentary Complex (VSC) of the Iberian Pyrite Belt (IPB), the Odiel River section and the Paymogo Volcanic lineament. Field evidence has allowed to distinguish two major groups of felsic rocks, which successively appear in the stratig...

Sumario:A field study is presented on two selected areas in the Volcano-Sedimentary Complex (VSC) of the Iberian Pyrite Belt (IPB), the Odiel River section and the Paymogo Volcanic lineament. Field evidence has allowed to 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 and geochemical evidence shows that at least the felsic rhyolitic succession in the Odiel River (and probably also in Paymogo) formed in a volcanic, environment, favouring a volcanic-pile model in the VSC
