carbonate mineralAny member of a family of minerals that contains the carbonate ion, CO32−, as the basic structural unit. The carbonates are among the most widely distributed minerals in the earth's crust; the most common are calcite, dolomite, and aragonite. Dolomite replaces calcite in limestones; when this replacement is extensive, the rock is called dolomite. Other relatively common carbonate minerals are siderite, rhodochrosite, strontianite (strontium-rich); smithsonite (zinc-rich); witherite (barium-rich); and cerussite (lead-rich). carbonate mineral [′kär·bə·nət ′min·rəl] (mineralogy) A mineral containing considerable amounts of carbonates.

| Nevertheless, numerous case studies have demonstrated extensive intermediate- and deep-burial cementation (and concurrent porosity/permeability losses) in carbonate aquifers, not only with carbonate minerals but also with sulfates, sulfides, and clay minerals (e. Finding only trace amounts of carbonate minerals on Mars isn't the only strike against the hypothesis that most of the Red Planet was once wet and warm (see p. Field checking of the sample site and surrounding soil sites containing the very high gold revealed altered rocks and copper carbonate minerals along what appears to be a mineralized East-West shear zone on the Huidong Concession. |
