[1] 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 mm to 14.31 0.24 mm and a subset of the (U-Th)/He ages range from 45.1 1… CONTINUE READING
