Syn-kinematic ferroan high-K I-type granites from Dschang in southwestern Cameroon: U–Pb age, geochemistry and implications for crustal growth in the late Pan-African orogeny

The Dschang granites, SW Cameroon, are post-Panafrican granitoids, hosted in Paleoproterozoic orthogneiss in the Western domain of the Central African fold belt. They include coarse-grained K-feldspar biotite granite and fine-grained magnetite granite. Magnetite forms nodules surrounded by a quartzo-feldsparthic halo. Major and trace element data of both granites show high SiO 2 , Al 2 O 3 , total alkalis and Ba and low TiO 2 , MgO, P 2 O 5 and...
