Great question to ponder.
As a "lay" astrogeologist here is "an" answer as I see it. So far we
only have the direct sampling of the Venusian atmosphere by the Soviet
mission. The isotope ratios of the Venusian
Sterling,
Interesting theory about Venus's atmosphere being blown off by a monster
impactor. Here is my objection: Where did the 100 bar carbon dioxide atmosphere
come from? Could one monster impactor blow off the existing atmosphere and
yet at the same time deposit a new one? Seems a stret

The best way to identify a Venus Stone would be by the Argon isotope
ratios. Argon-36 is the "natural" original isotope of Argon from the solar
nebula. Argon-4
Gee,
You mean, we could have been a nice "normal" planet like Venus if it wasn't for
the sheer bad luck of getting that ol' Devil Moon delivered to our doorstep?
Shucks, I hate to think of having to miss those 100-bar CO2 breezes, particularly
the ones with that whiff of fresh Argon, when I
More to the point where are all the earth meteorites? We should be able
to recognize them, (one would hope!), I guess as most of the earths
immediate surface is soil, or sedimentary rock(s), an earthite meteorite
would be pretty strange do date no true 'sedimentary' meteorites have
been found?, I

loose the moon (according to recent theory) was the best thing that could
have happened to us -- for life formation, that is.

Hi,
Actually, there are a number of sedimentary meteorites. It's just that
they are not acknowledged to be meteorites.
If you have the CDROM of the Catalogue, have the software assemble you a
list of "pseudometeorites" that are not irons.
Or just search for BLECKENSTAD (April 11, 1925)
