... ABSTRACT Burkina Faso is a gold-rich province whose mineral potential is mainly associated with the Birimian volcano-sedimentary belts and their intersections with Eburnean shear zones. Recently, the government of Burkina Faso completed a country-wide high-resolution airborne geophysical...

... 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...

... robust regional interpretation that reveals insights into the rift evolution of South Sudan and northern Kenya. The principal findings are evidence for an E-W trending shear zone linking the South Sudan basins to the Anza Rift, and the identification of a discrete N-S oriented basin related to a small...

.... The survey covered an area of approximately 2,750 km2, at line spacing of 400m. Gold mineralization in the Ashanti greenstone belt is mostly confined to the steeply dipping auriferous quartz veins. These veins are structurally controlled along major shear zones, which are common throughout the belt...
