About Wöhlerite GroupHide

Formula:

X₈(Si₂O₇)₂W₄

X = Na⁺, Ca²⁺, Mn²⁺,Ti⁴⁺, Zr⁴⁺ and Nb⁵⁺;
W = F^-, O^2-.

A group formally established by IMA in September 2020 (Proposal 20-D).
It has its name after the first described mineral of the group, wöhlerite (Scheerer, 1843). It includes 12 minerals (as of September 2024) with both monoclinic and triclinic structures. They occurs as accessory phases in various geological environments as nepheline syenites, alkali feldspar granite and skarns and calc-silicate marbles from different localities worldwide.

Formerly also known as 'Cuspidine Group.'
