文摘
- •
Bangangte syenomonzonites in West Cameroon are emplaced at ∼584 Ma.
- •
They are typical shoshonitic rocks generated by partial melting of an enriched mantle source.
- •
These rocks display a transitional feature of subduction-related and within-plate shoshonites.
- •
They emplaced in a post-collisional setting at the waning stage of Pan-African collisional orogeny.
