Petrographic and facies analyses of the "grey beds" of the Permian Viar Basin show a explosive volcanic activity, dacitic and rhyolitic in composition. "Grey beds" are constituted by a sequence of pyroclastic, redeposited volcaniclastic and propery sedimentary rocks which is here renamed "Grey Volcanoclastic Sequence"spaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Permian volcanismPyroclastic sequenceViar Basinjournal articleopen access
