East of the Matadi square degree, the transition from the metasedimentary protoliths of the Mayumbian Group to the clayey-sandy deposits of the Sansikwa Subgroup recalls a similar sedimentological history but distinct in their paleoenvironmental evolution, contrary to previous work establishing a discontinuity for these two lithostratigraphic units. Microscopic analysis coupled with field data interpretation revealed a depositional uniformity from the metasedimentary protoliths of the Mayumbian Group to the Sansikwa schists, a deformation synchronism and the absence of erosional unconformity at the base of the Sansikwa Subgroup, demonstrating a sedimentation singularity between the two units. This continuity places the Sansikwa Subgroup at the top of the Mayumbian Group and brings the Lower Diamictite to the base of the West Congolian Group.| Pages | 77-82 |
