Ore Concentrations Associated with Cavity Formations

The formation of cavities within geological formations often coincides with the deposition of valuable mineral resources. These concentrations can be attributed to a variety of factors, including geochemical reactions. Water rich in dissolved minerals percolate through the lithosphere, leaching preexisting cavities and depositing their mineral content as they crystallize. This process can result in a diverse range of ore types, from seams to larger, accumulated deposits.

  • Illustrations of such mineral-rich cavities include:
  • Metal sulfide occurrences often found in cavern systems
  • Crystal aggregations composed of quartz
  • Colemanite and Ulexite frequently associated with arid environments
