Referenza:
▪ Takai, Y. & Uehara, S. (2012): Rhabdophane-(Y), YPO4·H2O, a new mineral in alkali olivine basalt from Hinodematsu, Genkai-cho, Saga Prefecture, Japan. Journal of Mineralogical and Petrological Sciences, 107, 110-113.

Abstract:
Rhabdophane-(Y), ideal formulaYPO4·H2O, occurs in a druse of the Higashimatsuura basalt at Hinodematsu, Genkai-cho, Saga Prefecture, Japan. It occurs as short rod-like crystals and forms radial aggregates. Rhabdophane-(Y) is hexagonal, P6222, a = 6.959(2) Å, c = 6.384(2) Å, V = 267.7(1) Å3, Z = 3. It is yellowish white to yellowish brown in color with a silky to dull luster. The density is 4.54 g/cm3 (calc.). The strongest lines in the X-ray powder diffraction pattern are [d (I/I0) hkl] 2.821 (100) 102, 3.013 (77) 200, 6.026 (76) 100, 4.385 (47) 101, 3.480 (44) 110, 2.127 (28) 003, and 1.854 (26) 212.
