Resumen

Stress magnitudes throughout a NW-SE cross-section in El Berrocal granitic massif (Spanish Central System) have been analysed by means of finite element modelling. Topographic surface, lithological differences and recent compressive tectonic stresses have been included. Two kinds of models have been performed to study the influence of rheologic properties, one with average cortical mechanical properties and the other with the main lithologies. Horizontal tectonic stress magnitudes obtained in the last model have been checked with the recent stress ratio got by stress inversion of fault slip data. Horizontal tectonic load that better fits recent tectonic stress distribution is in the range of 10-15 MPa.
