Oxide mineral

Hydrokenoelsmoreite is a hydrous tungsten mineral with formula □2W2O6(H2O). Hydrokenoelsmoreite is a colorless to white, translucent isometric mineral. It has a Mohs hardness of 3, exhibits no cleavage and has a splintery fracture. It has a vitreous to adamantine luster. It is optically isotropic with an index of refraction of n = 2.24.

It forms from the oxidation within granitic pegmatite and in pegmatitic greisen. It has a structure based on a defect pyrochlore (A2B2O6O’).

It was first described for an occurrence in Elsmore Hill, New South Wales from where it takes its name.
