The Batié granitic massif in western Cameroon is NE-SW elongated, follows the regional foliation, and is parallel to the Kekem-Fotouni shear zone, which is the southwestern extension of the Tcholliré-Banyo Fault (TBF). This massif comprises two petrographic units: biotite granite and amphibole granite. Major, trace, REE, Sr-Nd isotopic, and new U-Pb data are used to constrain their nature and origin. The results indicate that they are high-K alkali-calcic with shoshonite affinity. The amphibole granite is metaluminous, whereas biotite granite is weakly peraluminous. Both granites are high-temperature I-type granites and crystallized under oxidizing conditions. Initial (87 Sr/ 86 Sr) 620 Ma ratios (0.7062-0.7080) and εNd 620 Ma (−12.6 to −8.9) indicate that the parental magmas were produced by partial melting of thick Paleoproterozoic crust and were mixed with felsic magma from the upper continental crust. Their Nd T DM typically varies from 1.68 to 1.96 Ga. The massif was mostly emplaced between 630 and 547 Ma during the transitional period between the crustal thickening (630-610 Ma) and the development of the shear zones, which began with sinistral movements (610-580 Ma) and continued with dextral movements (585-540 Ma). Plutonism continued during the dextral movements. The Batié granite is geochemically and isotopically similar to other post-collisional pan-African granitic massifs located along the TBF.
