The denudation dynamics of the Continental Rift of Southeast Brazil was studied.
- ss="label">•
The seaward-facing scarps are more denudated than the inland-facing scarps.
- ss="label">•
Lithology, climate, catchment relief and gradient, determine the denudation rates.

The results suggest a reduction in intraplate tectonic activity.
