Within the West African Craton, there is a large amount of mining activity covering resources such as gold, copper, cobalt, silver, tin, and zinc. [24] Artisanal mining activity in the craton dates back to the early 1960s which used quartz vein debris as a gold indicator. [25]

Cratons of South America and Africa during the Triassic Period when the two continents were joined as part of the Pangea supercontinent. A craton (/ ˈ k r eɪ t ɒ n / KRAYT-on, / ˈ k r æ t ɒ n / KRAT-on, or / ˈ k r eɪ t ən / KRAY-tən; [1] [2] [3] from Ancient Greek: κράτος kratos "strength") is an old and stable part of the continental lithosphere, which consists of Earth's two ...
The Kaapvaal Craton covers an area of approximately 1,200,000 km 2 (460,000 sq mi) and is joined to the Zimbabwe Craton to the north by the Limpopo Belt.To the south and west, the Kaapvaal Craton is flanked by Proterozoic orogens, and to the east by the Lebombo monocline that contains Jurassic igneous rocks associated with the break-up of Gondwana.
The cratons are from south to north, the Kalahari Craton, Congo Craton, Tanzania Craton and West African Craton. The cratons were widely separated in the past, but came together during the Pan-African orogeny and stayed together when Gondwana split up.
Ghana and Mali are the second and third largest producers of gold in Africa, respectively. [1] The Birimian terranes in the southern part of the West African craton are a mix of metamorphosed volcanic, sedimentary, and plutonic rocks and low-grade metavolcanics and metasediments.
The Man Shield (Leo-Man Shield or Leo-Man Craton) is a geological shield or craton in the southeast portion of the West African Craton. The shield is in part overlaid by gold -bearing Birimian formations .
The Zimbabwe Craton is an area in Southern Africa of ancient continental crust, being a part of the ancient continent of Western Gondwana, with rocks dating back to the early Archean Eon, possibly as early as 3.46 billion years ago . [1] The craton is named after the country of Zimbabwe where the majority of the
