Deposits Associated with Subterranean Formations
The formation of cavities within geological formations often coincides with the deposition of valuable mineral resources. These masses can be attributed to a variety of processes, including geochemical reactions. Water rich in dissolved minerals percolate through the rock, leaching preexisting cavities and depositing their mineral content as they precipitate. This occurrence can result in a diverse range of ore types, from seams to larger, layered deposits.
- Instances of such mineral-rich cavities include:
- Metal sulfide occurrences often found in solutionally developed depressions
- Geode clusters composed of calcite
- Borate deposits frequently associated with arid environments
