Minerals Africa - ib tug tseem ceeb nyiaj txiag kev pab

Africa tsis yog tsuas yog lub mainland, yog nto moo rau tus yus qhov thiab kab lis kev cai, qhov no yog xam qhovkev nyob rau hauv lub teb chaws nplua nuj mov ntawm natural resources. Nyob rau hauv lub equatorial tsam yog ib tug loj ib feem ntawm lub teb chaws, uas muab zoo tej yam kev mob rau txoj kev loj hlob ntawm forests, qhov loj feem ntawm uas yog 10% ntawm tag nrho cov cheeb tsam ntawm lub ntiaj teb hav zoov. Ntoo - lub ntsiab khoom exported.

Lwm teb chaws Africa yog pom tias yuav ua tau ib tug cov khoom muaj nqis trove ntawm lub Sahara suab puam, lub depths ntawm uas nkaum loj heev reserves ntawm cov dej tshiab. Nyob rau qhov no av loj yog cov coob cov niam dej ntawm cov ntiaj chaw, uas rightly dais lub npe ntawm lub zog pab nyob rau hauv teb chaws Africa.

Minerals Africa yog lub ntsiab lwm tus neeg ntawm cov kev pab rau qhauj ntawm ferrous thiab uas tsis yog-ferrous metallurgy, tshuaj qhauj rau tag nrho lub ntiaj teb. Nedra Africa yog nplua nuj nyob rau hauv phosphorite, chromite, titanium. Lub ntsiab reserves ores (uranium, cobalt, tooj liab, manganese) thiab minerals thiab zoo zoo nkauj tshooj (pob zeb diamond, kub) ntiaj teb teem rau no av loj. Minerals North Africa, uas yog sedimentary minerals, roj thiab roj, muaj lub ntiaj teb no tseem ceeb. Yav qab teb thiab Central Africa muaj nuj nqis magmatic minerals - ores ntawm ferrous thiab nonferrous co raws li diamonds.

Mineral deposits tshwm sim los ntawm qhov uas muaj qhov av loj tus nyem. Nyob rau hauv sab qaum teb, ntau tshaj qhov lowlands thiab subsidence, uas twb tau sau seas, thiaj li nag lossis daus tsim thee, manganese ores. East thiab teb chaws Africa teb sawv cev los ntawm plateaus thiab highlands, uas dabneeg tsim nyob rau hauv qhov chaw ntawm ntsug thiab kab rov tav zog ntawm lub platform, yog li no ib feem yog nplua nuj nyob rau hauv diamonds, kub, uranium ores.

Qhov no av loj muaj xws li ib unimaginable ntug uas minerals nyob rau hauv teb chaws Africa rau hauv daim ntawv qhia tsis tawm ib qhov chaw, cia txhua millimeter ntawm qhov chaw muaj ib tug mineral. Africa yog nto moo rau nws ore deposits, tus tsim ntawm uas hnub rov qab mus rau cov me nyuam yug ntawm tus Paleozoic. Tam sim no, lub platform yog raug ntawm qhov ncaj thiab sab qab teb ntawm lub teb chaws, thiab yog li ntawd, cov chaw no los ua tus concentration ntawm ore deposits. Tsaug rau qhov no "nudity" ntawm lub ancient platforms, cov pej xeem ntawm lub ntiaj chaw ua muaj tooj liab deposits nyob rau hauv South Africa, nyob rau hauv yav qab teb Rhodesia tsim chromite, Nigeria yog lub npe hu rau tin thiab tungsten, Ghana - manganese, thiab cov kob ntawm Madagascar yuav zoo muab rau tag nrho cov ntiaj chaw graphite. Tseem, Africans yog xav thov ua tsaug rau cov kub deposits ntawm lub Paleozoic. Tej zaum nyob rau hauv tej cheeb tsam ntawm teb chaws Africa thiab qab lub Western lub teb chaws, tab sis nyob rau hauv lub teb ntawm kub tsuas lub teb chaws, nyob rau hauv lub ntsej muag ntawm South Africa, ntev thiab khov kho tuav lub leading txoj hauj lwm.

Cambrian tsim terrestrial platforms yog suav tias yog qhov pib ntawm tso mednosnogo siv uas tsim xws minerals nyob rau hauv teb chaws Africa li tooj liab, tin, cobalt, hmoov txhuas, tungsten, thiab coj nws mus rau qhov kev txoj hauj lwm nyob rau hauv lub ntiaj teb no. Nyob rau hauv txoj kev loj hlob thiab zus tau tej cov saum toj no-hais cov kev pab Africa yog tus thib ob loj tshaj plaws nyob. Thaum lub sij hawm no lub sij hawm, lub teb chaws tsim deposits ntawm uranium ore thiab platinum. Nyob rau hauv lub depths ntawm lub hiav txwv tsim ntawm hlau ore, tab sis los ntawm lub deposition ntawm hiav txwv ntsev, cov pab African fossils yuav mus rau qhov uas tsis muaj-qib.

Thaum lub hlws ris ntawm lub Paleozoic thiab Mesozoic terrestrial platform av loj yog muaj ib tug nyob ntsiag to lub sij hawm nrog cov tsis muaj zog ntawm terrestrial platform, enabling tsim deposits ntawm thee, uas yog tshwj xeeb tshaj yog heev heev nyob rau hauv South Africa, Rhodesia, Congo thiab Madagascar.

Sahara thiab lub Sudanese African tiaj yog lub feem ntau complex nyob rau hauv cov qauv tsim, uas underwent faults thiab pob zeb outcrops, lifting thiab delamination ntawm ancient cov me nyuam yaus, muaj nuj nqis tso ntawm hlau, manganese ores thiab roj.
