Some fusion crust is present on all of these meteorites, the amount varying from 10% to 95%. The fusion crust is generally thin and black. Traces to abundant amounts of evaporite deposits are present. The deposit is white on most specimens except for 90003 where it has a greenish-blue color similar to that seen on EET90004 and 007. The interior of these Elephant Moraine C4's is medium gray. Cream-colored inclusions are present as is a small amount of metal.
