Formula:
K2TiSi3O9
Crystal System:
Hexagonal
Seems to be the Ti analogue of wadeite. No structural information reported.
Note: there is an erroneous formula (of davanite) reported in the reference.
Interestingly it is present as inclusions, up to 0.05 mm, in two iridium grains of a placer origin. Phlogopite and pectolite are also associated. The inclusions have regular outlines.
Note: the crystallography and density refer to a newly described phase from rischorrites of the Khibiny massif.
