So, hypothetically, if you're not supposed to be able to scratch the fusion
crust of a meteorite with a sharp object such as a knife, how do meteorites
such as Bensour receive "skid marks" when landing on sharp stone surfaces?

Hi All,
Continuing the mini-thread on extraterrestrial wannabes, I've uploaded
some images of an achondrite meteorwrong that I found recently. (For
the few list members that have already assisted me in identifying the
rock in question, these images are slightly better quality):

The fourth image shows the windowed interior. I welcome any of our
rock experts to offer opinions on probable ID -- gabbro, black granite,
diorite, etc. Specific gravity is ~3.0, and rock has no paramagnetism.
I was able to scratch the black surface with a pocket-knife; haven't
tried the white inclusions yet. No streak on a streak plate. --Rob
