Mchere Africa - zothandiza zofunika zachuma

Africa si kumtunda, anatchuka chifukwa cha chikhalidwe chosiyana ndi chikhalidwe, ichi ndi chibadidwe mu Africa wolemera kundipatsako kwa zachilengedwe. Mu zone ya kunyanja ndi gawo lalikulu m'dzikoli, lomwe lili momwe akadakwanitsira kukula kwa nkhalango, misa kachigawo amene ndi 10% ya malo okwana nkhalango Earth. Wood - waukulu mankhwala zimagulitsidwa.

Africa wina imatengedwa kukhala zakuya za Sahara chipululu, kuya amene kubisa nkhokwe chachikulu cha madzi abwino. Pa dziko lino ndi mitsinje yaikulu ya dzikoli, umene moyenerera dzina la mphamvu mu Africa.

Mchere Africa ndi ogulitsa chachikulu cha chuma malonda a akakhala ndi sanali akakhala zitsulo, makampani mankhwala kwa dziko lapansi. Nedra Africa ali olemera mu phosphorite, chromite, titaniyamu. Waukulu nkhokwe ores (ureniamu, cobalt, mkuwa, manganese) ndi mchere ndi zitsulo zamtengo wapatali (diamondi, golide) Dziko lolunjika pa dziko lino. Mchere Africa North, ndiwo nyanja mchere, gasi, mafuta, ndi tanthauzo lonse. Kumwera ndi pakati pa Afrika ofunika magmatic mchere - ores zitsulo akakhala ndi nonferrous komanso diamondi.

madipoziti mchere chifukwa mapangidwe mpumulo kontinenti a. Mu kumpoto, kuposa otsika ndi subsidence, amene anadzazidwa nyanja, kotero kuti mpweya anapanga malasha, manganese ores. East ndi Kumwera Africa umaimiridwa ndi zitunda zathyathyathya ndi okwera, amene mbiri aumbike mwa malo kuyenda ofukula ndi yopingasa a nsanja, kotero gawo ili wolemera diamondi, golide, ureniamu ores.

kontinenti uyu ali wotero malire sangaganize kuti mchere mu Africa pa mapu musatisiye danga, kwenikweni iliyonse millimeter malo lili ndi mchere makamaka. Africa anatchuka chifukwa madipoziti ake miyala, mapangidwe zapakati pa kubadwa kwa Paleozoic. Panopa nsanja poyera pa equator ndi kum'mwera kwa Africa, ndipo chotero, malo amenewa anakhala ndende ya madipoziti miyala. Zikomo kuti "manyazi" a nsanja akale, anthu a dziko anakhala madipoziti mkuwa zikupezeka South Africa, ku Southern Rhodesia zikukwaniritsidwa chromite, Nigeria amadziwika malata ndi tungsten, Ghana - manganese, ndi chilumba cha Madagascar mwina kupereka lonse dziko graphite. Komabe, Africa timayamikira madipoziti golide wa Paleozoic. Mwina m'madera ena a Africa ndi kumbuyo mayiko a azungu, koma m'munda wa migodi golide America, mu nkhope ya South Africa, wautali ndi wagwira molimba udindo kutsogolera.

Mathanthwe mapangidwe nsanja lapadziko imatengedwa chiyambi cha kuika lamba mednosnogo kuti anapanga mchere chotero mu Africa monga mkuwa, tini, cobalt, kutsogolera tungsten, nadza kwa udindo waukulu mu dziko. Pa chitukuko ndi kupanga zinthu tatchulawa Africa ndi wachiwiri kukula. Nthawi imeneyi, Africa anapanga miyala ya ureniamu miyala ndi pulatinamu. Mu kuya kwa nyanja anapangidwa wa zitsulo, koma mwa mafunsidwe a nyanja mchere, izi mafupawa zothandiza African a otsika kalasi.

Pamphambano ya Paleozoic ndi Mesozoic lapadziko nsanja Africa akukumana ndi chete nthawi ndi kusowa kwa kayendedwe ka nsanja lapadziko, kuwapangitsa anapanga miyala ya malasha, zimene zili zambiri makamaka South Africa, Rhodesia, Congo ndi Madagascar.

Sahara ndi Sudanese kumveka African ndi zovuta kwambiri dongosolo lomenyera, amene anakumana zolakwa ndi outcrops thanthwe, zochotsa ndi delamination ya maziko wakale, ofunika miyala ya chitsulo, manganese ores ndi mafuta.
