Carbonate Replacement Deposits (CRDs) » Geology Science

Ore Minerals: The primary ore minerals found in CRDs include sphalerite (zinc), galena (lead), and chalcopyrite (copper). These minerals often accumulate within the altered carbonate host rocks, creating economically viable deposits. Host Rocks: The host rocks for CRDs are carbonate rocks such as limestone and dolomite.The …
