Keilite
Keilite is an iron-magnesium sulfide mineral (chemical formula (Fe,Mg)S)) that is found in enstatite chondrites. Keilite is the iron-dominant analog of niningerite. Keilite is named after Klaus Keil (born 1934).
Occurrences
Examples of keilite occurrences are enstatite chondrites and the Zakłodzie meteorite. It appears to be confined to impact-melt influenced enstatite chondrites that were quenched. There are also some meteorites interpreted as impact-melt breccias that don't contain keilite. This is explained as a deeper burial after impact, which slowed cooling and enabled retrograde reactions (diapthoresis) to take place.

Wasted Years
by: ColdThere's a game life plays
makes you think you're everything they ever said you were
Like to take some time
Clear away everything I planned
Was it life I betrayed
for the shape that I'm in
It's not hard to fail
it's not easy to win
did I drink too much
could I disappear
and there's nothing that's left but wasted years
There's nothing left but wasted years
If I could change my life
Be a simple kind of man try to do the best I can
if I could see the signs
I'd derail every path I could
now I'm about to die
won't you clear away from me
give me strength to fly away
