About Rengeite
Formula:
Sr4ZrTi4(Si2O7)2O8
Colour:
Dark greenish brown
Lustre:
Adamantine
Hardness:
5 - 5½
Specific Gravity:
4.12 (Calculated)
Crystal System:
Monoclinic
Member of:
Name:
Named for Mt. Renge and the Renge metamorphic belt where jadeitite deposits are found.
Dimorph of:
Chevkinite Group.
See also strontiochevkinite and UKI-2008-(SiO:SrTiZr).
Found as a constitutent of lavender and green jade pebbles and boulders.
Structurally similar to hezuolinite; however, the O(1), O(2) and O(3) sites typical for hezuolinite are split into six sites in rengeite; also the Si(1)-O(7)-Si(2) angle is more bent in rengeite.
