Abstract

The Cañaveral Syncline in the Monfragüe National Park contains a complete Ordovician series, where the Upper Ordovician presents one of the most complete and best exposed sections of the Central Iberian Zone (ZCI). The detailed stratigraphic study of the series has made it possible to differentiate two major formations; the Puente del Cardenal Formation and the Villarreal de San Carlos Formation, as well as to recognise the sedimentary environments, significant surfaces and sedimentary crusts. By means of sequence stratigraphy, these surfaces have been calibrated by relating them to glacioeustatic variations deduced from the isotopic curves of Begström et al. (2009).
