A natural and instantaneous geophysical method for groundwater investigation in volcanic formations of Kibumba area has been developed. A geophysical evaluation using Electrical Resistivity method for groundwater investigation was carried out which involved the utilization of Vertical Electrical Sounding (VES) technique with Schlumberger array system. The study area is located within the igneous rocks, sedimentary, and metamorphic. The data acquired from twelve (12) VES stations using ABEM terrameter (SAS 1000) was tabulated in a table which shows the resistivity, the thicknesses and the number of layers for each VES station. The data was analysed using computer inversion software called INTERPEX1D, which yield an automatic interpretation of the apparent resistivity. The VES results revealed heterogeneous nature of the subsurface geological sequence. The geological profile sequence in the study area includes the topsoil (clay and fragments rocks and/or boulders formations of basalt), weathered layer (and/or fractured basalt) and fresh basement. The value for topsoil ranges from 10 Ωm to 1500 Ωm with thickness varies from 0.3 m to 10 m. The weathered layer (and/or fractured basalt) resistivity ranges from 100 Ωm to 2000 Ωm and thickness of 3 m to 20 m. The fresh basalt or bedrock basement ranges in value from 30 Ωm to 3000 Ωm with an unknown thickness due to the volcanic formation in the study area. However, the bedrock depth of all the VES stations from the earth’s surface could range from 1 m to 34 m. Based on the result of VES data, the proper area for making boreholes would be VES Kibumba 2, VES Kibumba 5 and VES Kibumba 9.

The formations of western Lake Tanganyika are mainly metamorphic intruded by magmatic intrusions and covered by some recent alluvium. They are particularly Mesoproterozoic formations with characteristic lithologies: Gneiss, quartzite, amphibolites, diorites and pegmatites. Regional tectonic has affected this sector generating brittle and planar microstructures which attest the compressive and extensive phases that affected this terrain, and even confirmed in the study of constraints by WIN TENSOR. The preferential orientation of NNW-SSE cleavages and foliations would justify the existence of a large regional fold contemporaneous with the D2 deformations of kibaran, while the double orientation of the fractures reflects two phases of local deformations that have been affecting Kavimvira. The highlighting of the faults at the regional scale is related to East African rifting.

The Bishusha salt sources are numerous. But as part of our research, we looked at four: Mariba 1, Mariba 2, Kazihiro and Makera. They contain various salts belonging either facies

This work describes the geochemical characteristics of rocks of the Bitungulu lava flow of the January 17, 2002 Nyiragongo volcano eruption.
In addition to the description in situ, samples of these rocks were analyzed in the University of Lubumbashi laboratory. Results show a high concentration of silica and mineralization dominated by nepheline. These rocks are basalts but they are close to trachy-basalts.
