Petrology and geochemistry of the Pan-African high-K calc-alkaline to shoshonitic–adakitic Bapé plutonic suites (Adamawa-Yade block, Cameroon): evidence of a hot oceanic crust subduction
Autor: Charles Nkoumbou, Joseph Mvondo Ondoa, Aurélie Ngamy Kamwa, Metang Victor, Jacqueline Numbem Tchakounté, Fuh Calistus Gentry
Publikováno v: International Journal of Earth Sciences. 110:2067-2090
The 60 km-long Pan-African Bape massif intruded in the Adamawa-Yade Archaean block is an excellent case for the study of subduction–collision-related magmatism, its origin by interaction among magmas from various sources, and its bearing on the evo
