Why this rock
is probably not a meteorite:
This "rock" (about 2" across) has both big and little blebs
of metal (the shiny or gray areas) and lots of vesicles.
In metal-bearing stony meteorites
(ordinary
chondrites), the metal grains ar all about the same size.
Also, the finder of this rock followed my advice and had a chemical
analysis done. The "rock" has a composition that is not
only inconsistent with a meteorite but suspicious even for a natural
rock from Earth (e.g.,
33% Fe2O3, 6% MnO, 0.15% MgO, 30 ppm Ni).
