Okenite (CaSi2O5·2H2O)[1] is a silicate mineral that is usually associated with zeolites. It most commonly is found as small white "cotton ball" formations within basalt geodes. Other minerals associated with okenite include gyrolite, prehnite, chalcedony and goosecreekite.

It was first described in 1828 for an occurrence at Disko Island, Greenland and named for German naturalist Lorenz Oken (1779-1851).[2]

[edit] Occurrence

Okenite is largely found in India, mainly within the state of Maharashtra. Other localities include Bulla Island, Azerbaijan; Aranga, New Zealand; and Bordo Island.
