Definition

1. Noun:
   • A light-colored mineral: A mineral composed of calcium magnesium carbonate (CaMg(CO₃)₂), which is a significant source of magnesium. It is used in various industrial applications, including as a refractory material in ceramics and as a soil conditioner in fertilizer.
   • A type of sedimentary rock: A rock that resembles limestone or marble but is distinguished by being rich in magnesium carbonate. This rock is often formed through a geological process where magnesium-rich fluids alter limestone.

Usage Examples

• Noun:
  • The quarry produces high-purity dolomite for industrial use.
  • The mountains in the region are composed primarily of dolomite.
  • Farmers applied dolomite to the field to adjust the soil's pH and add magnesium.

Advanced Usage
