Cavansite


Cavansite is a calcium vanadium silicate. Staples et al. (1973) named the mineral after the first few letters of its chemical components. This piece comes from the type locality in Oregon; Oregon material pales in comparison to the large crystals found in India, which changed standards for the species in 1987.

Small crystals of stilbite-Ca line a cavity in basalt, which hosted radiating blue spheres of cavansite to 2 mm. On the edge of piece, a tight grouping of spheres shows some excellent color. This is a nice specimen for Oregon! Note: the base of the specimen has been sawn. A Mineralogical Research label accompanies the specimen.
