- •
Sapphires from NW Cameroon are characterized to understand their genetic history.
- •
The sapphires were grown within alkaline magmatic and metamorphic environments.
- •
Zircon inclusions in part of the sapphires are Hf-U-Th enriched.
- •
Those inclusions were crystallized during Lower Cenozoic.
- •
