About KolovratiteHide

Formula:
NixZny(VO4)0.67(x+y) · nH2O
Colour:
Citrine-yellow, greenish yellow
Lustre:
Vitreous
Hardness:
2 - 3
Name:
After Lev Stanislovich Kolovrat-Chervinckii (1884-1921), Russian physicist and radiologist, Mineralogical Laboratory, Russian Academy of Science, St. Petersburg, Russia, who studied the Tyuya-Muyun uranium deposit, Kyrgyzstan.
According to Jambor & Lachance (1962), kolovratite is a hydrous zinc-nickel vanadate, or perhaps silico-vanadate, rather than a nickel vanadate as originally reported.

Probably needs a reinvestigation with modern methods.

Occurs in quartz schists and carbonaceous slates.
