Environments
Hydrokenoelsmoreite was approved in 2003 as a new mineral and named "elsmoreite". In 2010 it was redefined and renamed
"hydrokenoelsmoreite".
Localities
The Two Mile and Three Mile deposits, Paddy's River, Paddys River District, Australian Capital Territory, Australia,
are skarn deposits at the contact between
granodiorite and volcanic rocks.
ferritungstite is a secondary oxide that occurs with
ferrimolybdite associated with
scheelite. Both ferritungstite and
ferrimolybdite appear to have formed as weathering products of
scheelite
(AJM 22.1.41).
At the type locality, the Elsmore Tin Mine, Elsmore, Gough county, New South Wales, Australia, hydrokenoelsmoreite
was formed as a result of the oxidation of ferberite in the oxidised zone of
weakly mineralised granitic pegmatite dykes containing
tin, tungsten, molybdenum and
bismuth minerals (Webmin, AJM 13.1.51). Associated minerals include
quartz, white mica,
cassiterite, arsenopyrite,
native bismuth, chalcopyrite,
ferberite and molybdenite
(HOM).
At the Drakelands Mine, Plympton, Plymouth, Devon, England, UK, hydrokenoelsmoreite is associated with
wolframite and quartz
(HOM).
