About BaryliteHide

bluish white, colourless
Crystal System:
Named in 1876 by Christian Wilhelm Blomstrand from the Greek for βαρυζ = "heavy" and λιτθοσ = "stone", in allusion to its high density (specific gravity).
This page provides mineralogical data about Barylite.

Classification of BaryliteHide

Approved, 'Grandfathered' (first described prior to 1959)

9 : SILICATES (Germanates)
B : Sorosilicates
B : Si2O7 groups, without non-tetrahedral anions; cations in tetrahedral [4] and greater coordination

55 : SOROSILICATES Si2O7 Groups,Generally with no Additional Anions
1 : Si2O7 Groups, Generally with no Additional Anions with cations in [4] and higher coordination

14 : Silicates not Containing Aluminum
3 : Silicates of Be
