Environments
Although xiangjiangite was first published in 1978, to date (March 2024) it has been reported only from the
type locality.
Localities
At the type locality, the Jinyinzhai Mine, Suxian District, Chenzhou, Hunan, China, xiangjiangite occurs as
yellow to bright yellow earthy microcrystalline aggregates in the oxidised zone of a Permian (299 to 252 million
years ago) uranium deposit. Associated minerals include
sabugalite, variscite,
pyrite and quartz
(AM 64.466).
