Appearance
Cavansite is a very distinctive mineral which often forms in a bright blue colour and often occurs on top of members of the zeolite and apophyllite groups.
Uses and History
As far as I am aware Cavansite is only really used as a mineral specimen. It does contain Vanadium but not at a high enough concentration to be used as an ore.
Cavansite takes its name from CAlcium VANadium SIlicate – CaVanSi.
The type locality (original find location) is Owyhee Dam, Lake Owyhee State Park, Malheur County, Oregon, USA.
Mineralogy
Brilliant, bright blue to an aqua blue.
Hazards and Warnings
Almost all rocks, minerals (and, frankly, almost all other substances on earth) can produce toxic dust when cutting, which can cause serious respiratory conditions including silicosis. When cutting or polishing rocks, minerals, shells, etc, all work should be done wet to minimise the dust, and a suitable respirator or extraction system should be used.
