The continental margin of southeast Brazil is elevated. Onshore Tertiary basins and Late Cretaceous/Paleogene intrusions are good evidence for post breakup tectono-magmatic activity. To constrain the impact of post-rift reactivation on the geological history of the area, we carried out a new thermochronological study. Apatite fission track ages range from 60.7 +/- 1.9 Ma to 129.3 +/- 4.3 Ma, mean track lengths from 11.41 +/- 0.23 mu m to 14.31 +/- 0.24 mu m and a subset of the (U-Th)/He ages range from 45.1 +/- 1.5 to 122.4 +/- 2.5 Ma. Results of inverse thermal history modeling generally support the conclusions from an earlier study for a Late Cretaceous phase of cooling. Around the onshore Taubate Basin, for a limited number of samples, the first detectable period of cooling occurred during the Early Tertiary. The inferred thermal histories for many samples also imply subsequent reheating followed by Neogene cooling. Given the uncertainty of the inversion results, we did deterministic forward modeling to assess the range of possibilities of this Tertiary part of the thermal history. The evidence for reheating seems to be robust around the Taubate Basin, but elsewhere the data cannot discriminate between this and a less complex thermal history. However, forward modeling results and geological information support the conclusion that the whole area underwent cooling during the Neogene. The synchronicity of the cooling phases with Andean tectonics and those in NE Brazil leads us to assume a plate-wide compressional stress that reactivated inherited structures. The present-day topographic relief of the margin reflects a contribution from post-breakup reactivation and uplift.

L’inclusion scolaire d’enfants en situation de handicap est la norme légale au Brésil depuis 1996. Cependant, l’institution Lugar de Vida [Lieu de vie], qui a vu le jour en 1990 au sein de l’université de São Paulo, considère avant tout cette inclusion comme l’un des axes de travail d’une proposition éducative et thérapeutique pour les enfants autistes et psychotiques. Les auteurs de cette contribution sont membres fondateurs du laboratoire universitaire LEPSI 2 [Études et recherches psychanalytiques et éducationnelles sur l’enfance] auquel le centre d’éducation thérapeutique Lugar de Vida est associé. Ils présentent ici les idées qui orientent et organisent le fonctionnement du dispositif baptisé « Éducation à visée thérapeutique », dans le contexte du débat sur la redéfi nition des frontières classiques généralement établies entre soin et éducation. Ils s’appuient pour cela sur une référence singulière aux idées freudiennes en matière d’éducation.
