Wassonite
Wassonite is an extremely rare sulfide mineral with chemical formula TiS.〔 Its discovery was announced in a 2011 NASA press release as a single small grain within an enstatite chondrite meteorite called "Yamato 691", which was found during a 1969 Japanese expedition to Antarctica. This grain represents the first observation in nature of the synthetic compound titanium(II) sulfide. The mineral was named after John T. Wasson, a professor at the University of California, Los Angeles and was approved by the International Mineralogical Association. == References ==
