Mineral Deposits Associated with Cavity Formations
The formation of cavities within geological formations often coincides with the deposition of valuable mineral resources. These deposits can be attributed to a variety of processes, including geochemical reactions. Fluids rich in dissolved minerals percolate through the substrate, leaching preexisting cavities and depositing their mineral content as they precipitate. This occurrence can result in a diverse range of deposit formations, from seams to larger, stratified deposits.
- Examples of such mineral-rich cavities include:
- Galena and Sphalerite mineralization often found in solutionally developed depressions
- Cave pearls composed of quartz
- Borate deposits frequently associated with ancient evaporate basins
