Neoproterozoic magmatic accretion and Pan-African reworking-differentiation of mafic crust derived from an enriched mantle: evidences from structural analysis, petrology and geochemistry of the Ketté gold district (Eastern Cameroon) 14

Ghislain Ngassam Mbianya, Olivier Vanderhaeghe, Sylvestre Ganno, Michel Gregoire, Mathieu Benoit, Rodolph Loïque Azefack Mbounou, Jonas Didero Takodjou Wambo and Timoleon Ngnotue

The Ketté district in eastern Cameroon hosts gold mineralization associated with rocks of the Central African Orogenic Belt. This study shows that these rocks originated from deep Earth processes involving molten material derived from the mantle and later modified within the crust. Intense heat and pressure caused partial melting and deformation, producing a variety of granitic rocks and structures. Understanding this evolution helps clarify the processes responsible for gold mineralization and provides a guide for future mineral exploration in similar regions.
