Abstract: Microscopic analysis and interpretation of the geochemical signatures of heavy minerals collected during stream sediment execution in the Kimpangu agglomeration and surrounding area have revealed the existence of four mineralogical families: ilmenites, garnets, spinels and pyroxenes. The geochemical signatures of these minerals confirm that they belong to Lherzolitic and pyroxenitic enclaves for the first three families, and to continental enclaves for pyroxenes. These mantle and crustal enclaves were eroded by kimberlitic magma, the two intrusions of which are located at Mbanza Yanga and south of Kimpangu.
