Some scientists believe that at least one meteorite found in Antarctica
preserves evidence of ancient life on Mars.
I think that Earthites would have a very high amount
of Maskelynite should plagioclase be present in the
parent rock. The impacts from earth would be so
energetic as to create more of this mineral than in
Martian meteorites.
The atmospheric composition would then, just as the
case with Martian
Steve and List,
Thanks for your contribution to this discussion.
Your information may help lead to the finding of an
Earthite. Best, Dirk Ross...Tokyo

List,
Which would be the most likely event that
potentially could have created an Earthite meteorite?
What age would it be? And of what earth rock
material and how could it be determined (other than
fusion crust)? Would they not be more valuable than
Lunites?
Thanks for any comments.
Hi, Ken, List,
I've posted on Earthites or terrestrial meteorites
a couple of times before; they're somewhere in the
archives... Howver.
Likely event? More energetic than the impacts
that launched the Martian meteorites off Mars, since
our atmosphere is thicker, hence harder to get back
Hi,
Some scientists are aware of the possibilities
and the problems. See (from 1994):
