Resumen

Calcite e-twin density (twins/mm) and percentage of cal cite grains with one and two twin sets fromsparry grains that fill microveins were used to precise the differential stress related with the inversion of the Cameros Basin, a Mesozoic sedimentary basin located in the northwestern part of Iberian Chain (Spain).The results obtained using techniques based on the percentage of twined grains yield better resultsthat those techniques based on twin density. The deduced stress magnitudes fit well with the differential stress interval proposed for fold-thrust belt domains. Combination of twin data with rockmechanics data provides adequate estimations of differential stresses
