Dolomite, a mineral composed of calcium magnesium carbonate, originates from sedimentary rocks. It forms through the alteration of limestone or lime mud, and precipitation of calcium and magnesium ions in water. Discovered by Déodat Gratet de Dolomieu in the Dolomite Mountains of Italy, it is now found worldwide, including in the United States, Canada, and China. Due to its hardness and durability, dolomite finds applications in construction materials like concrete and asphalt. Additionally, it serves as a valuable source of magnesium and calcium for agricultural purposes.
