Resumo

lntraplate deformation in the eastern zone of the iberian Peninsula is characterized by strike-slip faulting during Tertiary. Gradient pattern of Bouguer Anomaly Map of the Spanish Central System-Iberian Range linking zone are related to main crustal faults. Gradients pattern has been analysed by means of a raster type Geographic lnformation System. Two main gradien orientations associated with Spanish Central System structures (NE-SW) and with iberian Range structures (NW-SE) have been established. Gradient map and artificial shading image have been used to quantify dextral slip along NOSE faults. Slip value reach a figure of 34 km. Assuming that the slip began in Oligocene times, movement rate between the Spanish Central System and the lberian Range Castilian Branch is 0.93 mm/y. Considering a Middle Miocene start a 2.2 mm/y slip rate is computed.
