Estructuras tectónicas en el basamento de la cuenca de Madrid y su reflejo en la cobertera sedimentaria

Abstract

A group of NW-SE strike-slip faults have been recognized in the basement of the eastern part of Madrid basin. The sedimentary data considered concern m a in ly isopach map of Miocene Intermediate Unit as well as palaeogeographical distribution of depositional environments. The structural research has been focused on faults and folds analysis which affect both the Altomira Range (eastern margin of the Madrid basin) and the Neogene cover in the basin. These basement faults controlled the tectonic structuration of Altomira Range during upper Oligocene-lower Miocene and the Neogene sedimentation
