Why do Campo del Cielos all have that characteristic knobby look?
Like yes, I understand the entire thing about liquid nitrogen and Campo crystals and stuff like that.
However, surely most of the material would have come from inside the meteorite, which is basically just a solid hunk of metal - so how does shattering it create such a distinctive look? Is it something to do with Campo's iron-nickel crystal structure?
Also if anyone could tell me more about Campo's colour / texture (which honestly seems quite distinct also) that would be great!
