Hydrokenoelsmoreite is a hydroustungstenoxide mineral with formula □2W2O6(H2O). Hydrokenoelsmoreite is a colorless to white, translucentisometric mineral. It has aMohs hardness of 3, exhibits no cleavage and has a splintery fracture. It has a vitreous to adamantine luster. It is optically isotropic with anindex of refraction of n = 2.24.
It forms from theoxidation offerberite within graniticpegmatitedykes and in pegmatiticgreisenveins. It has a structure based on a defectpyrochlorelattice (A2B2O6O’).
It was first described for an occurrence in Elsmore Hill,New South Wales,Australia from where it takes its name.
