Génesis de nódulos de cuarzo en el Paleozóico de las sierras de Vicort y Alagairén (Cordillera Ibérica)

Abstract

[ES] En formaciones samíticas y pelíticas del Paleozoico inferior de la Rama Aragonesa de la Cordillera Ibérica se generan nódulos de sílice que son apreciables a escala microscópica y mesoscópica. Con formas subesféricas y/o elipsoidales, tienen origen diagenético y están constituídos por asociaciones en mosaico de cristales de cuarzo de muy distinto tamaño y hábito cristalino. Se ha observado una relación bastante estrecha entre características tectónicas y alineaciones y orientación de los nódulos, y se han comprobado distintas etapas en su desarrollo, desde la formación de un mosaico microcristalino hasta la inferida reorientación y anastomosamiento de cristales preformados que dan lugar a un monocristal.

[EN] A particular feature in the paleozoic materials from Iberian Mountains (Spain) is the presence of diagenetic silica-nodules. The nodules, from microscopic to mesoscopic size and almost always constituted by a mosaic association of neoformed quartz-crystals, appear to have been originated in relation with tectonic processes. Three steps are differenciated, from early one, defined by a microcrystalline structure, to the nowadays one, formed ocasionally by quartz monocrystals.
