Mineral deposit - Rainwater | Britannica.com

Mineral deposit - Rainwater: Each of the deposit-forming processes discussed above involves the transport and deposition of ore minerals from solution. But solutions can also form deposits by dissolving and removing valueless material, leaving a residuum of less-soluble ore minerals. Deposits developed as residues from dissolution are called residual deposits.
