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).
