abstract={A petrographic and a structural study of the Gounbela region (Adamawa-Yad¨¦) basement have been made. This included a macroscopic and a microscopic approach. The lithology is made up of biotite-amphibole gneisses and amphibolites (belonging to the amphibolite facies); of biotite-muscovite and pink granites with a porphiryc granular texture showing a syn-to late tectonic character of rocks. The Gounbela tectonic present four deformational phases; D<SUB>1</SUB>, D<SUB>2</SUB>, D<SUB>3</SUB>, D<SUB>4</SUB>. D1 is materialized by the S1 foliation; D<SUB>2</SUB> is marked by the S<SUB>2 </SUB>schistosity resulting from the tranposition of S<SUB>1</SUB> foliation. D<SUB>3</SUB> is charasterized by F<SUB>3</SUB> folds and C<SUB>3</SUB> shear planes. The D4 deformational phase is made up of veins and faults. The major faults directions N130-N140 are similar to those belonging to the Lam¨¦ cretaceous Serie in Tchad, suggesting that they may have been occurred during the Atlantic opening.},
