Plutonic igneous environments
Two forms of native titanium have been found; the first, found in
granite, crystallises in the hexagonal system,
and the second occurs as minute inclusions in garnet from an ultrahigh pressure
metamorphic complex, and crystallises in
the tetragonal system (Mindat); also as microscopic inclusions in coesite
At the type locality, Orebody 31, Luobusha Mine, Qusum county, Shannan Prefecture, Tibet, China, titanium has been found in chromitite associated with kyanite and coesite (Mindat).
At the Great Fissure eruption, Tolbachik volcano, Kamchatka Krai, Russia, hexagonal titanium has been described from fumaroles (Mindat).
Titanium has been recovered from heavy-mineral separates prepared from granite taken from the margin of the Bezymyannyy pluton, eastern Yakutia, USSR. The separates also contain native tin, lead, copper, iron, zinc, nickel, gold, aluminum and tin-antimony and copper-zinc compounds (AM 76.1435).
Titanium-bearing minerals include:
