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 factors, including geochemical reactions. Solutions rich in dissolved minerals percolate through the lithosphere, dissolving preexisting cavities and depositing their mineral content as they precipitate. This phenomenon can result in a diverse range of deposit formations, from veins to larger, accumulated deposits.
