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.
