Chemical Composition of Meteorites

 

Manganese / Iron

MnO / Fe2O3(T) vs. Fe2O3(T) + MgO

 



MnO / Fe2O3(T)

 

The ratio of manganese to iron does not vary much within different groups of meteorites. The MnO/Fe2O3(T) ratio (or Fe/Mn or FeO/MnO) is not as reliable a test for meteorites as some sources imply, although ratios of <60 are inconsistent with lunaites and >50 are inconsistent with eucrites, for example.
