This work aims at the understanding of the petrogenesis of Lukoshian metamorphic formations in the Kisenge aera. Here are presented detailed petrographic study of the gneisses and amphiboles of this sector and the new geochemical data of major elements as well as a sketch of the geological map of the study area. The macroscopic petrographic study has distinguished, in the gneisses of the Kisenge sector, two lithological facies which are gneisses and granitic gneisses. And quartz veins are observed in amphiboles. The geochemical study on basis of major elements revealed that these gneisses derived from a metamorphic evolution of granites and granodiorites of calc-alkaline series. They are therefore formed in a geodynamic context of subduction. While the amphiboles are of basic composition, resulting from the metaborphism of gabbro.
