Dovyrenite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Ca6Zr(Si2O7)2(OH)4
System:
Orthorhombic
Colour:
colorless
Hardness:
3 - 4
Name:
After the type locality, the Dovyren Bald Mountain, Yoko-Dovyren layered massif, Northern Baikal Region, Russia.
Exhibits a new type of modular structure with stacking of the tobermorite-like and the rosenbuschite-like layers parallel to (010). Single-crystal structural data point to an incompletely occupied Ca(2) site from the rosenbuschite module which is confirmed by microprobe analysis.

Classification of Dovyrenite

Approved
Approval Year:
2007
9.BE.23

9 : SILICATES (Germanates)
B : Sorosilicates
E : Si2O7 groups, with additional anions; cations in octahedral [6] and greater coordination
