About HydrokenoelsmoreiteHide

Formula:

◻₂W₂O₆(H₂O)

Alternative formula based on data obtained by Mills et al. (2016) for 3C and 6R polytypes:
(◻,Na,H₂O)₂(W,Fe³⁺,Al)₂(O,OH)₆·H₂O.

Colour:

White, black, dark green, yellowish, brownish

Lustre:

Adamantine

Hardness:

Crystal System:

Isometric

Member of:

Elsmoreite Group > Pyrochlore Supergroup

Name:

Originally called elsmoreite, for the Elsmore tin mine and/or the town of Elsmore, Australia. It was renamed in 2010 according to the nomenclature for the pyrochlore supergroup. The name elsmoreite was promoted to group level and this species was renamed to indicate its membership in the group, with dominant water and a vacancy (keno).

Type Locality:

ⓘ Elsmore Tin Mine (Elsmore Tin lodes), Elsmore, Gough Co., New South Wales, Australia

Formerly called elsmoreite (if chemically pure) or ferritungstite (Fe-bearing variety, with W>Fe) or alumotungstite (Al-bearing variety; W>Al).
V- and Cr-rich varieties with black colour are known from the Clara mine, Black Forest.

See also hydroplumboelsmoreite (formerly jixianite).

The recent crystallochemical data (Mills et al., 2016) was obtained from material ("elsmoreite", formerly known as "ferritungstite") from Hemerdon mine (now Drakelands mine) in Devon, UK. The 3C and 6R polytypes were recognized (see hydrokenoelsmoreite-3C and hydrokenoelsmoreite-6R).
