Niningerite - Wikipedia, the free encyclopedia
Niningerite is a magnesium-iron-manganese sulfide mineral with the chemical formula (Mg,Fe,Mn)S that is found in enstatite chondrite meteorites. Niningerite is the magnesium-dominant analog of keilit...

Troilite and niningerite occur in approximately equal proportions interspersed within the silica. Most chondrules have enstatite rims and their cores contain silica and sulfides, although some have silica rims with a mixture of enstatite and silica in their cores.
