pisarakoita

Pisarokite is a rare mineral discovered in 2018, named after the Pisarovo mine in Bulgaria, where it was first found. It is a complex borate mineral with the chemical formula Na2Ca2B5O9(OH)5. Pisarokite crystallizes in the monoclinic system and typically forms small, colorless to white crystals or aggregates. Its hardness on the Mohs scale is approximately 4.5, and it has a specific gravity of around 2.7.

The mineral is notable for its unique crystal structure and its association with other borate minerals in the Pisarovo mine. It is often found in cavities within basaltic rocks, alongside minerals such as datolite, calcite, and quartz. Pisarokite's formation is believed to be the result of hydrothermal processes, where hot, mineral-rich fluids interact with the host rock.

Due to its rarity and the specific conditions required for its formation, pisarokite is not commonly used in industry or jewelry. However, it is of interest to mineralogists and collectors for its scientific and aesthetic value. The study of pisarokite contributes to our understanding of the complex processes involved in the formation of borate minerals and the geology of the Pisarovo mine.
