[meteorite-list] Maskelynite

[Pekka Savolainen]

Hi,

a type of naturally occurring glass having the composition of a 
plagioclase series feldspar,
created by the vitrification of plagioclase by shock melting in 
meteorites and meteorite impacts,
so as far as I know, Maskelynite is not formed or found on Earth w.o. 
impacts.
