Mineral Deposits Associated with Subterranean 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 mechanisms, including hydrothermal activity. Fluids rich in dissolved minerals seep through the rock, dissolving preexisting cavities and depositing their mineral content as they crystallize. This process can result in a diverse range of mineral assemblages, from lenses to larger, accumulated deposits.
- Illustrations of such mineral-rich cavities include:
- Lead-Zinc deposits often found in solutionally developed depressions
- Geode clusters composed of quartz
- Borate deposits frequently associated with ancient evaporate basins
