Dolomia

Dolomia is a type of rock primarily composed of the mineral dolomite, which is similar to limestone but contains magnesium. It forms in marine environments where calcium and magnesium-rich seawater deposits layers of this sediment over time. Dolomia is often used as a building material and in the production of cement, due to its durability and natural abundance. It also plays a key role in the carbon cycle, as it can store carbon dioxide over geological timescales. Geologically, dolomia indicates past environments with specific chemical conditions, helping scientists understand Earth's history.
