korraldasite

Korraldasite is a naturally occurring mineral composed of potassium, rubidium, and iron, with the chemical formula (K,Rb)2Fe3+(OH)(SO4)2. It is a sulfate mineral and was first discovered in the Kola Peninsula of Russia. The mineral is relatively rare and is typically found in pegmatite deposits. Its color can range from white to pale yellow or pink. Korraldasite crystallizes in the monoclinic crystal system.

The discovery of korraldasite is credited to a team of Russian mineralogists. Its name honors the Russian mineralogist Nikolai Korraldas. Due to its rarity, it is not a widely used mineral in industrial applications. However, it is of interest to mineral collectors and researchers studying geological formations. Further research may reveal more about its geological context and potential associations with other minerals.
