Ca2MgCO34

Ca2MgCO34 is a chemical compound with the formula Ca2Mg(CO3)2. It is a carbonate mineral that belongs to the dolomite group. This compound is known to occur naturally as a rare mineral. Its crystal structure is rhombohedral. Ca2MgCO34 is isostructural with dolomite, CaMg(CO3)2, meaning they share the same crystal structure, but Ca2MgCO34 has a higher calcium to magnesium ratio. The presence of calcium and magnesium in its composition gives it distinct properties compared to pure calcium carbonate (calcite) or pure magnesium carbonate (magnesite). Its formation is typically associated with certain geological environments, often within carbonate rock sequences. Due to its rarity, it is not widely encountered in industrial applications or common geological formations. Research into its properties and occurrence continues to expand our understanding of carbonate mineralogy.
