I think some information on this has been posted before, but I don't know if all
of this has. Of note:

"The dolomite did not acquire a fusion crust. Instead, the surface exposed to
the heat of re-entry burned off. This could point to one reason why we have not
yet found a sedimentary martian meteorite ? it lacks that tell-tale black fusion
crust that meteorite hunters look for.

?It will be difficult to recognize them,? says Brack. ?There is no obvious sign
or feature that they are meteorites. The only way would be to have a mass
spectrometer to measure the oxygen isotopes 16, 17, and 18, as well as nickel,
manganese, and chromium, because Martian silicates are expected to be enriched
in these elements.? "
