Abstract

The “apalachiense” relief of Monfragüe's National Park, constituting to a series of quartzitic combs with direction NW, between which they find slopes, hills and valleys following the same direction, for the dismantlement of the Cenozoic cover that was covering the substratum (still present in the central sector) and encasement of the Rivers Tajo and Tiétar. It emphasizes that you upset beech remains of terraces inside the Park, but if in his edges. In edge N (basin of the Campo Arañuelo), there stay remains of six fluvial terraces of relative importance attributed to the River Tajo (with heights relative to the talweg between 100-20 m). In the edge S, six levels attributed to former fluvial drainage network, which assimilate to the River Tajo, which more recent level this one over 200 m on the current river. Neotectonics readjustments, that they rejuvenated the relief, producing the elevation of the socle and cover, at the time that diversions in the path of the network(net), up to his structure and end encasement (for supertax and / or antecedence).
