|Name:||Named for the element.|
Two forms of native titanium have been found - one, found in granite, crystallizes in the hexagonal system, the other as minute inclusions in garnet from an ultrahigh-pressure metamorphic complex crystallizes in the tetragonal system (see Tetragonal Titanium).
Hexagonal α-Titanium was described from fumaroles of the Northern Break of Great Fissure Tolbachik Eruption of 1975 in 1992.
Considered doubtful for a longer time, finally approved in 2010.
