Las ignimbritas de Castellar de N'Hug (Pirineo Catalán)

Abstract

[ES] En la zona de Castellar de N'Hug existen importantes intercalaciones de materiales piroclásticos entre las facies detríticas de la Unidad Roja Inferior (Autuniense). Se trata de ignimbritas de distinta naturaleza, que presentan en ocasiones una extensión considerable, y que están asociadas a depósitos plinianos de caída y a depósitos de oleadas piroclásticas. Estas ignimbritas derivan de erupciones plinianas generadas durante la formación de una gran caldera volcánica que corresponde al complejo riolítico de Greixer.'

[EN] Different well developed ignimbrites occur interbedded within terrigenouds etritic facies in the Lower Red Unit (Autunian). These ignimbrites are related to plinian fall deposits and pyroclastic surge deposits. They resulted from plinian eruptions produced during the formation of the Greixer rhyolitic volcanic caldera. The areal extension of these ignimbrites can occasionally be very wide (further than 80 km away from the vent).
