Makes total sense to me. This is how we determine the origin of most
terrestrial rocks as well!! (i.e. volanics!)

Not sure what this has to do with anything. Please expound.

Which parent body do you suggest? Do you have any data we do not?

You are correct. Point being the gases trapped within the SNC's DO MATCH
the SAMPLED martian atmosphere!

Actually this is OK. Earth's atmosphere hasn't really changed in the
last 12 M.a either! Samples of earth gases found 10 M.A, trapped in
crystal inclusions, does match the current atmosphereic composition.

It si secualtion based on REAL data collected in the lab and on MARS! It
will not be FACT until we return MANY samples from Mars (someday!)

That is BS!! If you are going to make such bold statements, please back
them up with some sort of basis.
