About Lovozerite GroupHide

Formula:
A3D3G2M(HxSi6O18) · nH2O (x = 0-6)
M= Zr, Ti, Fe3+, Ca
G= Ca, Mn2+, Na, ◻
A= Na, Ca
D= Na, ◻
0≤ x ≤ 6 ; n= 0-1
Group of complex zeolite-like cyclosilicates. All minerals of this group contain Na as an essential mineral-forming constituent. They occur in only alkaline rocks.
IMA-accepted nomenclature established by Pekov et al. (2009).
