• Hingganite-(Ce): Mineral information, data and localities.

    www.mindat.org/min-1905.html The Ce analogue of Hingganite-(Y). The existence of a Ce-analogue was known for a long time and the name hingganite-(Ce) was in rather common use in the mineralogical literature, but it was only accepted as a valid species in 2004 (IMA2004-004) from Tahara, Hirukawa-mura, Gifu Prefecture, Japan (Miyawaki et al.2006).
