This project represents the last two years of the project to strengthen the research capacity and geological service of the CRGM through joint scientific research with the RMCA at a higher scientific level than previously. The research activities for this project focus on four geological topics. Study of the geological context of the cross-border region of the Malebo Pool (Kinshasa and Brazzaville) and mapping. Mineralogical and geochemical study of pegmatites in the Boma region. Study of the Mao Massif (Bas-Congo, DRC). Study of the lower diamictite : comparison between the regions of Kimuaka, Sansikwa and Kasi (Bas-Congo, DRC). The project also includes the creation of a database with the search functionality containing all the collected data within the framework of the project.
