Zorluk: OrtaMineral Resources and Mining in Africa

Match each African mining location on the left with its corresponding major mineral resource on the right.

  • Jos Plateau (Nigeria)Cassiterite (tin ore) and columbite
  • Great Dyke (Zimbabwe)Platinum group metals and chromium
  • Witwatersrand Basin (South Africa)Placer gold deposits hosted in conglomerate rock layers
  • Koidu District (Sierra Leone)Alluvial diamonds mined from gravel deposits

Cevap

Jos Plateau matches Cassiterite (tin ore) and columbite; Great Dyke matches Platinum group metals and chromium; Witwatersrand Basin matches Placer gold deposits hosted in conglomerate rock layers; Koidu District matches Alluvial diamonds mined from gravel deposits.
Each mining center correctly corresponds to its primary geological mineral output: Jos Plateau with tin/columbite, Great Dyke with platinum/chromium, Witwatersrand with gold, and Koidu with diamonds.

Adım Adım Çözüm

1
Identify the primary mineral deposit associated with West African young granite ring complexes.
Jos Plateau in Nigeria is associated with tin (cassiterite) and columbite mining.
Geological weathering of younger granites led to placer concentrations of tin and columbite in the plateau's alluvium.
2
Locate the major geological rift/intrusion feature in Southern Africa known for strategic industrial metals.
Great Dyke in Zimbabwe is linked to platinum and chromium.
The lopolithic intrusion structure of the Great Dyke contains linear bands rich in chromite and platinum group minerals.
3
Recall the major gold-producing geological formation in South Africa.
Witwatersrand Basin is linked to placer gold deposits in conglomerate reefs.
Deep-level mining in the Witwatersrand targets gold contained in ancient Precambrian conglomerate rocks.
4
Associate diamond-producing regions in Sierra Leone with extraction methods.
Koidu District matches alluvial and kimberlite diamonds.
Koidu is central to Sierra Leone's diamond fields along river beds and primary pipes.
