The Meteoritical Bulletin entry for Mount Egerton is a bit sparse. This is a book describing the meteorite and its discovery. (5MB)
It’s a very strange meteorite comprised of intergrown enstatite crystals and nuggets of Fe-Ni (check the above image for photos of some etched specimens!).
Here are some photos of a 22.3 gram fusion-crusted fragment. As with most aubrites, the crust is tan (last photo). Black areas are exposed Fe-Ni inclusions.
