Dolomite UPSC NOTE

 Why in News

  • Addressing the long-standing “dolomite problem,” researchers have found that dolomite crystals require cycling of saturation conditions to grow

  • The findings provide new insights into how dolomite is formed.

  • Also found how modern dolomite is primarily found in natural environments with pH or salinity fluctuations

  • As per the simulation’s predictions, frequent cycling of a solution between supersaturation and undersaturation can speed up dolomite growth by up to 10 million times.

  • Dolomite is slightly soluble in water, and it will effervesce in cold dilute hydrochloric acid.

  • Dolomite is formed by the precipitation of calcium and magnesium carbonates from seawater. 

  • It can also be formed by the alteration of limestone or by the metamorphism of limestone or dolostone.

  • Dolomite is a valuable mineral with a wide range of uses.
