Environments
Jingwenite-(Y) is a new mineral, approved in 2021 and to date (January 2024) reported only from the type
locality.
Localities
At the type lcality, the Yushui Mine, Mei county, Meizhou, Guangdong, China, jingwenite-(Y) is an
abundant component of the sediment-hosted stratiform copper deposit. It occurs
in bedded/massive sulphide-bearing ore and is associated with bornite,
chalcopyrite, galena,
xenotime-(Y), nolanite,
thortveitite, roscoelite,
baryte and quartz.
Jingwenite-(Y) is of epigenetic (formed later than the surrounding or underlying rock formation) origin and it
appears that heavy rare earth elements and vanadium were added to the
sediment-hosted stratiform copper system via leaching of abundant heavy minerals
in the footwall red sandstone by oxidised basinal (pertining to a
large low-lying area, often below sea level) brines. The abundance of jingwenite-(Y) at Yushui indicates that it could
potentially be a valuable resource for heavy rare earth elements and vanadium
(AM 108.192-196).
