Geology of Mineral Resources

• Economic Concentrations of Minerals - Ores
  • Economic Concentration Factors of Selected Metals
  • Non-Fuel US Mineral Imports
• Ore Deposit Origins
  • Igneous Processes
    • Igneous Intrusions - e.g., chromite, diamonds
    • Hydrothermal Deposits
      • Disseminated ores - e.g., porphyry copper deposits
      • Vein & Stockwork ores
      • Black Smokers - seafloor hydrothermal deposits
  • Metamorphic Processes
    • Contact Metamorphism
    • Regional Metamorphism
  • Sedimentary Processes
    • Evaporites - e.g., Halite, Gypsum
    • Placer - e.g., Gold
    • Glacial - e.g., Sand & Gravel
  • Biological Processes - phosphorus
  • Weathering Processes
    • Residual Soils - e.g., Bauxite
    • Secondary Enrichment
• Plate Tectonics & Mercury Ore Deposits

Environmental Impact of Mineral Development

• Impact of Prospecting
• Impact of Mining & Ore Processing
  • Mine Waste - Tailings - Ajo Mine Overburden - Grasberg Mine Tailings, Irian Jaya, Indonesia
  • Open Pit Mining - e.g., Homestake, Lead, SD - Bingham Canyon, UT
  • Underground Mining
  • Solution Mining
• Water Pollution - e.g., Acid Mine Drainage
• Air Pollution - e.g., Acid Rain
• Biological Impacts - e.g., three "burn" areas
• Social Impact - e.g., Gold Rush (saloons, whorehouses, general wickedness)
• Environmental Regulation
• Biotech Remediation

Recycling & Sustainability

• Global Cycling
• Sustainability
