Ore Concentrations Associated with Subterranean 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 factors, including geochemical reactions. Water rich in dissolved minerals infiltrate through the rock, leaching preexisting cavities and depositing their mineral content as they evaporate. This phenomenon can result in a diverse range of ore types, from lenses to larger, stratified deposits.
- Examples of such mineral-rich cavities include:
- Galena and Sphalerite mineralization often found in karst formations
- Geode clusters composed of quartz
- Borate deposits frequently associated with dried lakebeds
