New detrital petrographic and thermochronologic constraints on the Late Cretaceous–Neogene erosional history of the equatorial margin of Brazil: Implications for the surface evolution of a complex rift margin

Basin Research, Volume 36, Issue 1, January–February 2024.
Since the Late Cretaceous, the equatorial margin of Brazil has undergone a rift phase, with the erosion of a moderate rift escarpment, a Late Cretaceous–Paleogene post‐rift phase, with major drainage reorganization and significant vertical erosion, and a Late Oligocene‐to‐Recent post‐rift phase, with moderate vertical erosion and river headwater ...
