THE MINERAL YUKSPORITE

• Chemistry: (K, Ba)NaCa2(Si, Ti)4O11(F, OH) - H2O , Hydrated Potassium Barium Sodium Calcium Titanium Silicate Fluoride Hydroxide.
• Class: Silicates
• Subclass: Inosilicates
• Uses: Only as a mineral specimen.
• Specimens

Yuksporite is a rare and unusually named mineral. It is one of only a few silicate minerals where titanium frequently substitutes for the silicon in the SiO4 tetrahedrons. In many silicates, aluminum freely substitutes for silicon, but in yuksporite it is the significantly larger titanium ion that does the substitution. Yuksporite is named for the Yukspor Mountains of the Kola Peninsula from where it was first discovered in the early part of the twentieth century. It is one of many exotic mineral species that are emerging from the vast mineral resources of the former Soviet Union. It can have a nice yellow-rose coloration and is certainly a unique mineral.
