DOLOMITE
It is a carbonate mineral composed of calcium magnesium carbonate and is commonly found in sedimentary rocks.
Chemical formula for dolomite is CaMg(CO₃)₂
PHYSICAL PROPERTIES OF DOLOMITE
- Color: White, gray, pink, green, brown, or black
- Luster: Vitreous to pearly
- Streak: White
- Hardness: 3.5 – 4 on Mohs scale
- Specific Gravity:2.85 – 2.90
- Cleavage:Perfect rhombohedral cleavage
- Fracture: Conchoidal to uneven
- Transparency:Transparent to translucent
- Reactivity: Reacts weakly with cold dilute hydrochloric acid (HCl) but effervesces more vigorously when powdered or in warm acid
Dolomite may exist in sedimentary rocks and may precipitate as a secondary mineral from the alteration of limestone.
