Formula:
Y4(Si,H4)4O12-x(OH)4+2x
Crystal System:
Monoclinic
Name:
Named after Thomas Fredrik Weiby Barth (1899-1971), professor of geology, Oslo University, Norway.
A mixture of metamict and crystalline phases, among them thalénite-(Y), xenotime-(Y) and kainosite-(Y).
Described as a new mineral by Neumann & Nilssen (1968). Friis (2018, 2019) has re-examined the original material (neotype) and showed that the samples are heterogeneous, and a mixture of metamict and crystalline phases. The original chemical analyses were done on heated material, which removed elements such as C and F, and thus erroneously. The mineral was discredited by IMA in 2016.
