I have had an opportunity to see samples of the Chelyabinsk
meteorite. I think that these stones are almost as distinctive as the
fireball was spectacular.
Many samples have deep fractures.
Many samples have patches of reddish fusion crust. The reddish crust
may be secondary crust. It formed on broken surfaces or perhaps in the lower
portions of regmaglypts. The reddish crust is smoother than the primary
crust.
Some samples have a brownish "dusty" appearance. Despite being
freshly collected.
Has anyone else noticed these or other interesting characteristics
of this meteorite?
Thanks,
Peter
