Carbonate Replacement Deposits (CRDs) » Geology Science
Carbonate Replacement Deposits (CRDs) are geological formations that result from the replacement of pre-existing carbonate rocks by ore minerals, often metals such as lead, zinc, and copper. These deposits are significant sources of base metals and are of economic importance due to the concentration of valuable minerals within them.
