Resumen de Nuevos datos microestructurales sobre la existencia de deformaciones precámbricas en la Sierra de la Demanda (Cordillera Ibérica)
Microstructural surveying of pebbles of the early Cambrian «Anguiano Conglomerates» permits to recognize a variety of microstructures and textures that resulted from syn-metamorphic (up to 400°C, low-temperature greenschists facies) ductile deformations. The source area of the conglomerates was likely a Neoproterozoic basement that recorded the imprint of the Cadomian orogeny and that contained penetratively deformed metamorphic rocks in addition to the arc-related ingeous suites that have been detected or inferred so far in other realms of the northern Iberian Massif
