Having the qualities of or containing calcium carbonate In the case of Coral Calcium, having a special digested form of calcium carbonate that is highly bio-available See Cancer Study for varying results
- Rich in the chemical compound calcium carbonate (CaCO3) For example, calcareous grassland develops on soils derived from calcium carbonate-rich rocks such as LIMESTONE
Formed of calcium carbonate or magnesium carbonate by biological deposition or inorganic precipitation in sufficient quantities to effervesce carbon dioxide visibly when treated with cold 0 1 normal hydrochloric acid Calcareous sands are usually formed of a mixture of fragments of mollusk shell, echinoderm spines and skeletal material, coral, foraminifera, and algal platelets
