What is "yuksporite"

n. (context mineralogy English) A rare pink inosilicate mineral with orthorhombic crystals.

Yuksporite is a rare inosilicate mineral with double width, unbranched chains, and the complicated chemical formula K(Ca,Na)SrMn(Ti,Nb)(O,OH)(SiO)(SiO)(HO,OH). It contains the relatively rare elements strontium, titanium and niobium, as well as the commoner metallic elements potassium, calcium, sodium and manganese. As with all silicates, it contains groups of linked silicon and oxygen atoms, as well as some associated water molecules.

Yuksporite is a member of the umbite group that has just two known members, umbite, KZrSiO.HO, and yuksporite. It was first reported in 1922, from nepheline syenite occurrences in the Kola Peninsula, Russia, and named by Alexander Fersman for the locality, near Mount Yukspor.
