Rietmeijer (TEM): Finds the amorphous Si-bearing material to be un-GEMS like. He sees another Si-rich glassy material which has Mg,Fe,S, etc, that appear more GEMS like. He reports Fe-Ni sulfide compositions, including some that are enriched in S, and some that have very high Ni, and cannot have originated from partial volatilization of troilite. He sees both kamacite and taenite (by ED). He sees brookite grains which appear to be in the epoxy only and are probably contamination (?).
