Zelmir, To me the very fact that there are no known Earthites, (other than Tektites) or any known 'venusites', (or indeed any meteorites of types not believed to be from asteroids/persolar nebula/mars/moon/and maybe mercury?) raises some interesting questions...
Either, 1. The mechanism we believe that allows rocks to escape from Venus and Earth (i.e. larger planets with a thick atmosphere and high gravity) is wrong and they can't or don't get ejected very often at all. 2. or we have misidentified some of the Lunar or Martian or other rock types when in fact they are from other planet(s) (although this is unlikely) 3. or statistically we have not found them because we just haven't found enough meteorites yet (although we (mankind) have found quite a few now!). 4. or they look [very different] to what we are used to, and they are actually all around us! Personally I think that we still have a lot to learn about atmospheric rock interactions and particularly about ejections on planets like Venus, I mean a rock has to undergo two atmospheric 'meltings' to arrive here on earth. I'ts different with the Martian rocks because the atmosphere is very thin, that must make a big difference to the ejected rock 'yield'?
