Entwodiksyon: Distribisyon resous mineral nan Afrik, Divizyon Zòn Mineralizasyon nan kontinan Afriken an, Lis Ekipman pou abiye minrè pou Gine Placer Gold Mines {{0}
Kat jeyolojik nan nouvo inite tektonik ak pi gwo depo mineral sou kontinan Afriken an WC-Western kalite kraton; Wo-Western Orogenic Belt Kalite; WR-Western Rift kalite; Kalite kraton EC-lès; EO-EASTERN OROGENIC BELT TIP; Er-Eastern Rift type .
These mineral resources are not only diverse in type, but also in huge reserves, especially strategic minerals such as platinum, manganese, chromium, gold, and diamonds, which occupy an important position in the world. This paper will start from the geological tectonic background of the African continent, combine mineralization and geological history, and systematically analyze the distribution characteristics and formation mechanism of the main mineral resources in Lafrik .
1. Jeyolojik background tektonik nan kontinan Afriken an estrikti a jewolojik nan kontinan Afriken an se sitou ki konpoze de twa kalite litosfè: kalite kraton, kalite senti orojèn ak kalite rift . fòmasyon evolisyon li yo gen yon enfliyans lò sou distribisyon mineral ki soti nan dèt ak {2 { Distribisyon seleksyon resous mineral Tanzani an
1 . 1 Distribisyon litosfè kraton: sitou distribye nan lwès ak Afrik di sid, ki gen ladan kraton Afrik de Lwès la, kraton Kongo a ak Kalahari Craton . Mineralizasyon: sitou ki te fòme BIF-kalite fè minrè, greenstone-kalite minrè lò, ak mineral tankou CHROMIUM, nikèl, ak platinum eleman gwoup (PGE).
1.2 Distribution of orogenic lithosphere: Mainly distributed in eastern and northern Africa, including the East African orogenic belt and the Sahara Neoproterozoic orogenic belt. Features: Formed from the Paleoproterozoic to the Neoproterozoic, mainly due to horizontal crustal accretion and plate collision and Amalgamasyon . mineralizasyon: sitou fòme lò, kwiv, CHROMIUM, Platinum Group, Manganèz, fè, nikèl, vanadyòm, Titàn, iranyòm ak lòt depo metal.
1 . 3 Distribisyon nan litosfè Rift-Type: sitou distribye nan lès Afrik, ki gen ladan Belt la Rift Afriken . karakteristik: ki te fòme nan Mesozoic la ak Cenozoic Eras, ak ouvèti a nan Oseyan Atlantik la ak Separasyon nan Afriken ak Afriken Kontini Ameriken {{{Es Detwi Afriken yo. Jaden, depo metal baz, ak depo metal radyo -aktif.
2. Distribisyon gwo resous mineral nan Afrik 2 . 1 metal presye ak mineral estratejik.
Eleman gwoup platinum (PGE): sitou distribye nan konplèks la Bushveld nan Lafrik di sid, kontablite pou plis pase 80% nan rezèv mondyal yo, ak pre relasyon ak wòch yo debaz-ultramafic nan Archean la Litosfè . Gold yo: Lafrik di sid, Gana, Mali, Tanzan yo ak nan yo. Witwatersrand Basin in South Africa is the world's largest gold field, mainly related to the Archean greenstone belt and the Neoproterozoic orogenic belt lithosphere. Diamonds: Mainly distributed in Botswana, South Africa, Angola and the Democratic Republic of the Congo, related to kimberlite in the cratonic lithosphere and placer deposits in the Rift litosfè .
2.2 Ferrous Metals and Alloy Minerals Manganese: South Africa and Gabon are the world's major manganese ore producers, related to Archean BIF-type iron ore deposits and Paleoproterozoic sedimentary manganese deposits. Chromium: South Africa and Zimbabwe are the main producing areas, related to layered basic-ultramafic rocks Nan Archean Cratonic litosfè a . fè: sitou distribye nan Lafrik di sid, Gine ak Moritani, ki gen rapò ak Archean BIF-kalite depo minrè ak Paleoproterozoic depo fè minrè sedimantè.
2 . 3 Metals ki pa gen anpil ak ra kwiv: Zanbi ak Repiblik Demokratik Kongo a se zòn prensipal pwodwi yo nan Copperbelt Afrik Santral la, ki gen rapò ak depo yo sedimantè kwiv nan neoproterozoik orojenik la ki gen rapò ak {{3} Ki gen rapò ak depo yo kwiv-cobalt nan Copperbelt Afrik Santral la . Uranium: Namibi ak Nijè yo se zòn yo pwodwi prensipal yo, ki gen rapò ak depo yo Paleozoik sedimantè iranyòm ak depo yo iranyòm nan Mesozoic ak Cenozoic Lithosphere la.
2 . 4 Mineral ki pa metalik fosfat: Mawòk ak lwès Sahara se pi gwo zòn nan fosfat nan mond lan, ki gen rapò ak Paleozoik Marin sedimantè depo fosfat . grafit yo: Mozayik ak tanzani yo se pwodui prensipal yo, ki gen rapò ak zòn yo, ki gen rapò ak pwodui yo.
3. Geological evolution and mineralization of African mineral resources The formation of mineral resources in Africa is closely related to its complex geological evolution history. In the Archean Eon, the craton-type lithosphere was dominant, forming BIF-type iron ore, greenstone-type gold ore, and chromium, nickel, and platinum group element deposits; Soti nan Paleoproterozoic a neoproterozoic a, litosfè a orojèn te dominan, fòme lò, kwiv, CHROMIUM, Manganèz, fè, nikèl, vanadyòm, Titàn, iranyòm ak lòt depo; Nan Mesozoic la ak Cenozoic, litosfè a Rift-kalite te dominan, fòme dyaman, lwil oliv ak gaz jaden, baz metal ak depo metal radyo-aktif .
