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 (⁸⁷Sr/⁸⁶Sr)_{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.

喀麦隆西部的Batié花岗岩地块是NE–SW延长的，遵循区域性叶状，并与Kekem–Fotouni剪切带平行，后者是Tcholliré–Banyo断层（TBF）的西南延伸。该地块包括两个岩石学单元：黑云母花岗岩和角闪石花岗岩。主要的，痕量的，REE，Sr-Nd同位素和新的U-Pb数据用于约束其性质和起源。结果表明，它们是具有高钾钠石亲和力的高钾碱钙。闪石花岗岩为金属质，而黑云母花岗岩为弱铝质。两种花岗岩均为高温I型花岗岩，并在氧化条件下结晶。初始（⁸⁷ Sr / ⁸⁶ Sr）_620嘛比（0.7062-0.7080）和的εNd _620嘛（-12.6至-8.9）表明，母岩浆是由厚的古元古代地壳部分熔融而产生的，并与上大陆壳的长英质岩浆混合。他们的Nd T_糖尿病通常在1.68至1.96 Ga之间变化。在地壳增厚（630–610 Ma）和剪切带发展之间的过渡时期，断层大部分位于630至547 Ma之间，这始于左旋运动（610–580 Ma）。 ），然后继续右旋运动（585-540 Ma）。在右旋运动过程中，柏拉图主义继续存在。Batié花岗岩在地球化学和同位素上与沿TBF分布的其他碰撞后的泛非花岗岩地块相似。
