Hello List,
I received a beautiful meteorite specimen from Anne Black at Impactika the other day, (Mt. Tazerzait, 23.21 grams) and I'm amazed at the beautiful chrome crystals that reside in the vugs of this stone. Upon researching this rock I came across several references to "extraterrestrial chromite." I have seen these words before in reference to other minerals that are in meteorites as well.
My question(s) is this; What's the difference between terrestrial and extraterrestrial minerals? Is there some sort of signature that defines them? Is it isotopic or chemical?
I'm looking for specifics as opposed to generalities.
Thanks,
Larry
