395 p.The southeast Brazilian passive margin is elevated and shows evidence for post rift tectonic and magmatic activity (sedimentary basins and alkaline intrusions). We undertook a structural and thermochronological study (apatite fission tracks and U-Th/He) to constrain the timing, magnitude, stress orientation and causes of the reactivations. We infer, from the modelling of thermochronological data, two exhumation phases during Late Cretaceous and Neogene over the whole studied area. A third phase during the Paleogene is restricted to the borders of the onshore Tertiary basins. The amount of exhumation attributable to post-rift reactivation from the coast to the Serra da Mantiqueira reaches about 4.5 km. The study of the seismic profiles...
