Zincovelesite-6N6S

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Zn3(Fe3+,Mn3+,Al,Ti)8O15(OH)
Colour:
Black
Lustre:
Metallic, Sub-Metallic
Hardness:
Specific Gravity:
5.158 (Calculated)
Crystal System:
Trigonal
Name:
The rootname velesite is given for the discovery locality near the city of Veles.
The first Fe3+-dominant member of the högbomite supergroup and, thus, can be considered as a parent species of a new mineral group.

Uniaxial intergrowths of zincovelesite-6N6S with nežilovite are observed at the type locality, in silicate-baryte zones of a metasomatic rock.
