Superman ReturnsEdit

Lex Luthor enters the Metropolis Museum of Natural History and steals the Addis Ababa L9 Pallasite Meteorite, which was discovered at the Kebe Mine in Addis Ababa, Ethiopia. It is described in the exhibit display as "sodium lithium boron silicate hydroxide with fluorine". According to the exhibit display, the meteorite was discovered in 1978 - the year that Superman: The Movie was released.

Incidentally, in 2007, a white and harmless mineral with the above chemical formula (except without fluorine) was discovered by Rio Tinto Group researchers in a mine in Serbia.

Lex uses the meteorite in his quest to create a new kryptonite landmass. In addition, he uses a shard leftover from processing it to create a kryptonite shiv, which he uses to stab Superman.
