keilite Keilite is an iron-magnesium sulfide mineral (chemical formula (Fe,Mg)S)) that is found in enstatite chondrites.〔http://webmineral.com/data/Keilite.shtml Webmineral〕 Keilite is the iron-dominant analog of niningerite.〔http://pubs.nrc-cnrc.gc.ca/journals.old/mineral/mineral40/tcm-168740-6.pdf 〕 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.
