La tectónica alpina en el borde norte del Sistema Central español y su enlace con la cuenca del Duero

Abstract

This report is focused to describe the main alpine structures located in the northern edge of the Spanish Central System and the linking zone with the Tertiary Duero basin. A review of the main characteristics of the alpine tectonic phases is given. From these data, differences between the Gredos zone, dominated by N-S and E-W faults, and the Guadarrama zone, in which N 70° E reverse faults with N 140° E and N 10° E strike-slip faults are present, can be observed. The pattern of drainage of this area shows three main orientations, coincident with the alpine faults activated during the Guadarrama tectonic phase, which reveals the relationship between the present drainage pattern and the Alpine orogeny.
