- On the Upper Ordovician unconformity in the Pyrenees:New evidence from the La Cerdanya area J.M. Casas O. Fernández Ciencias de la Tierra Variscan Pyrenees Upper Ordovician Angular unconformity In recent years, contradictory reports about whether or not an unconformity exists at the base of the UpperOrdovician succession of the Pyrenees have been made. In the Cerdanya area (Central Pyrenees), good outcropevidence for this unconformity is displayed at the base of the Rabassa conglomerates. In this area, the UpperOrdovician rocks overlie a tilted Cambro-Ordovician sequence, displaying an angular unconformity and indicatinga break in the stratigraphic series. Moreover, the existence of such an unconformity is supported by the distributionof Variscan minor structures, suggesting that the Cambro-Ordovician and the Upper Ordovician stratainitially had different orientations before the main Variscan folding. 2007 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50550205 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.2 Vol.5
