- •
We report U–Pb age and chemical data for detrital monazites from 5 African rivers.
- •
The monazite U–Pb age data defined peaks corresponding to the Pan-African Orogeny.
- •
The age peaks are 20–40 Myr younger than the zircon age peaks of the same rivers.
- •
Detrital monazite REE–Th–U systematics are linked to their potential genesis.
- •
Detrital monazites provide a record of syn- to post-collisional events.
