| Why this rock is probably not a meteorite:
1) No fusion crust.
2) Like meteorites that are brecciated, this rock appears to contain
pieces of older rocks that are glued together somehow. Note that some
of the "clasts" are missing and there are holes where the
clasts used to be. Geologists would say that the clasts have been
"plucked." Plucked clasts mean that the clasts are harder
than the matrix that holds them together. That's common in terrestrial
sedimentary rocks but unknown in meteorites. Although some lunar regolith
breccias consist of hard clasts in a friable matrix (e.g., sample
60016), such a
rock would not withstand being blasted off the Moon (or an asteroid)
and the hard landing on Earth.
|What is it?
Probably a conglomerate of some kind.
