"The African continent is characterized by extensive mineralized, Precambrian orogenies, divided by younger basins and tectonic zones. The resulting pattern is more distinctive than the structure of other shield areas. It is more complex, however, than the pattern of the younger Andean and Alpine orogenies, at least five groups of cycles having been superimposed between 3,300 and 450 million years. Sedimentation, orogenic evolution and six alignments control ten metallogenetic belts of Africa."
