About KatayamaliteHide

Nobuo Katayama
Formula:
KLi3Ca7Ti2(SiO3)12(OH)2
Crystal System:
Monoclinic
Name:
Named in honor of Nobuo Katayama (片山信夫) (17 January 1910, Tokyo, Japan - 4 March 1997), mineralogist and professor at the Tokyo Imperial University and later at Kyushu University.
Described as the hydroxyl analogue of baratovite, which had originally been described as fluor-dominant. Some mineralogists now claim that baratovite is also hydroxyl- rather than fluor-dominant, and that baratovite and katayamalite are therefore the same species, with the name baratovite having priority. At present this situation has not been clarified and katayamalite remains an IMA-approved species.

Originally described as having a triclinic symmetry (space group C-1) by Kato & Murakami (1985). The structure was redetermined with monoclinic symmetry (space group C2/c) by Andrada et al. (2013).
