• Limestone: The Calcium Carbonate Chemical Sedimentary Rock

    DefinitionGeologyFormationCostUsesOther usesFutureAdvantagesIssuesResourcesMission\"Limestone\" means any rock formed mostly of calcium carbonate (CaCO3), but to geologists, limestone is only one of several types of \"carbonate rocks.\" These rocks are composed of more than 50% carbonate minerals, generally the minerals calcite (pure CaCO3) or dolomite (calcium-magnesium carbonate, CaMg[CO3]2) or both.在geology上查看更多信息

    Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO3)2. In old USGSpublications, dolomite was referred to as magnesian limestone, a term now reserved for magnesium-deficient dolomi
