40 Facts About Vaterite

What is Vaterite?

Vaterite, a rare mineral form of calcium carbonate, often intrigues scientists and gem enthusiasts alike. Its unique properties and formation make it a subject of fascination.

1. Vaterite is one of three crystalline forms of calcium carbonate, the others being calcite and aragonite.
2. It was first discovered in 1901 by German mineralogist Heinrich Vater, hence the name.
3. Vaterite is less stable than calcite and aragonite, often transforming into these more stable forms over time.
4. It typically forms in low-temperature environments, such as in biological systems or during the early stages of mineral formation.
5. Vaterite can be found in some freshwater pearls, giving them a unique luster.

Physical Properties of Vaterite

Understanding the physical characteristics of vaterite helps in identifying and differentiating it from other minerals.

6. Vaterite has a hexagonal crystal structure, which is quite different from the trigonal structure of calcite and the orthorhombic structure of aragonite.
7. It is usually colorless or white, but impurities can give it a range of colors.
8. Vaterite has a Mohs hardness of about 3, making it relatively soft compared to other minerals.
9. Its specific gravity ranges from 2.5 to 2.6, which is lower than that of calcite and aragonite.
10. Vaterite is birefringent, meaning it splits light into two rays, creating a double image when viewed through a polarizing microscope.

Formation and Occurrence

The formation and occurrence of vaterite are influenced by various environmental factors.

11. Vaterite often forms in biological systems, such as in the shells of some mollusks and the otoliths of fish.
