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

• "Dolomite formation": Refers to the geological process by which dolomite rock is created, often involving the alteration of pre-existing limestone.
  • The study focused on the conditions necessary for dolomite formation in ancient seas.
• "Dolomitization": The specific process where limestone is converted into dolomite by the replacement of calcium with magnesium.
  • Dolomitization can significantly alter the porosity of a reservoir rock.

Variants and Related Words

• Dolomitic (adj): Describing something that contains or is related to dolomite.
  • The soil has a dolomitic composition, which is beneficial for certain crops.
• Dolostone (n): A synonym for the sedimentary rock dolomite, used primarily in geological contexts.
  • The layer of dolostone is easily identifiable in the canyon's strata.

Synonyms

• Magnesian limestone: An older term sometimes used for dolomite rock, emphasizing its magnesium content.
• Pearl spar: A historical name for a crystalline variety of the mineral dolomite.

Related Phrases and Compounds
