ABSTRACT We present the interpretation results of a fixed-wing airborne geophysical survey flown over the northeastern part of Burkina Faso for detailed geological mapping and mineral exploration. This part of Burkina Faso is known for its significant gold potential that is mainly associated with Birimian greenstone belts as well as with major shear zones. In addition, numerous non-auriferous mineralized occurrences including base metals (Cu and Zn), rare metals (V), ferrous (Ti-Fe), non-ferrous (Al, Ni and Cr) and precious metals (Diamond) are encountered within the Birimian basement rocks and the Neoproterozoic sedimentary rocks of the Taoudéni Basin. The magnetic data analysis with the 3D MVI outcomes resulted into a new structural map highlighting several faulting systems of different age, nature and direction. These are suggested to have played a key role in the gold mineralization control within this area. Several kimberlite targets with magnetic response similar to known diamondiferous kimberlite pipes occurring in this area have been identified. The 3D MVI performed on selected targets allowed to map the suggested kimberlite pipes in 3D. The analysis of the gamma-ray spectrometric data helped detect several uranium targets associated with the Neoproterozoic sediments of the Taoudeni Basin and with the pegmatites of the Paleoproterozoic basement. A mineralization targeting and prediction analysis has been performed on the acquired airborne geophysical data and the Landsat imagery. It yielded several favorability maps for various commodities thus significantly increasing the mineral potential of this area.
