Jixianite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Pb(W,Fe3+)2(O,OH)7
System:
Isometric
Colour:
red to brownish red
Hardness:
3
Name:
For the type locality at Ji Xian (= Ji County), China.
A variety of Elsmoreite Group

Jixianite (Liu 1979) is 'plumboelsmoreite'. In the absence of a crystal-structure study, it is not possible to know the dominant anion of the dominant valence at the Y site of jixianite.

Compare also hydrokenoelsmoreite (formerly ferritungstite, alumotungstite and elsmoreite).

Classification of Jixianite

Discredited 2010
4.DH.15

4 : OXIDES (Hydroxides, V[5,6] vanadates, arsenites, antimonites, bismuthites, sulfites, selenites, tellurites, iodates)
D : Metal: Oxygen = 1:2 and similar
H : With large (+- medium-sized) cations; sheets of edge-sharing octahedra
48.4.2.1

48 : ANHYDROUS MOLYBDATES AND TUNGSTATES
4 : Miscellaneous
7.15.9

7 : Oxides and Hydroxides
15 : Oxides of Mo and W
