Ma'adanai Afirka - wani muhimmin tattalin arziki hanya

Afirka ba kawai babban yankin, shi ne shahara ga rarrabe hali da al'adu, da wannan ne muhimmi a nahiyar arziki da wadata na albarkatun. A Equatorial zone ne babban ɓangare na nahiyar, wanda ya samar da ganiya yanayi na ci gaban da gandun daji, da taro sulusi da murabba'i na wanda shi ne 10% na jimlar yankin na Duniya gandun daji. Wood - babban samfuri fitar dashi.

Wani Afirka da aka dauke su a taska trove da hamadan Sahara, cikin zurfin wanda boye sararin reserves na sabo ruwa. A wannan nahiyar su ne mafi girma da waɗansu kõguna na duniya, wanda gaskiya kai da sunan samar da makamashi da albarkatun a Afirka.

Ma'adanai Afirka ne babban kaya na albarkatun ga kamfanonin na ferrous da kuma wadanda ba ferrous metallurgy, sinadaran Enterprises ga dukan duniya. Nedra Afirka ne mai arziki a phosphorite, chromite, titanium. Babban reserves ores (uranium, cobalt, jan, manganese) da kuma ma'adanai da karafa masu daraja (lu'u-lu'u, zinari) duniya mayar da hankali a kan wannan nahiyar. Ma'adanai a Afirka ta Arewa, waxanda suke da sedimentary ma'adanai, gas da kuma man fetur, da duniya muhimmanci. Kudanci da kuma tsakiyar Afirka daraja magmatic ma'adanai - ores na ferrous da nonferrous karafa, kazalika da Diamonds.

Ma'adinai adibas sa da samuwar nahiyar ta sauƙi. A arewa, fiye da filayen kwarinta, kuma subsidence, wanda aka cika tekuna, don haka kamar yadda hazo kafa kwal, manganese ores. Gabas da Kudancin Afirka wakilta plateaus da tsaunuka, wanda tarihi kafa a wuri na tsaye da kuma a kwance yunkuri na dandali, don haka wannan bangare ne mai arziki a cikin Diamonds, da zinariya, uranium ores.

Wannan nahiyar na da irin wannan baba misali gefe cewa ma'adanai a Afirka a kan taswira ba bar wani sarari, a zahiri kowane millimeter na sarari ya ƙunshi wani musamman ma'adinai. Afirka shi ne domin ta shahara tama adibas, da samuwar wanda nema a mayar da haihuwar Paleozoic.
