What is it?
This is a sawn face of the Dhofar
007, a coarse-grained, brecciated eucrite. A generous
meteorite dealer sent this beautiful sample to me for free when
I bought some lunar meteorites. I reluctantly show this photo because
this is a highly atypical meteorite that superficially resembles some
terrestrial rocks. In detail, however, there is a piece of iron-nickel
metal at the center of every rusty spot in the image. Neither metallic
iron nor iron-nickel ever occurs in any natural Earth rock. If
it's got rusty metal, it's either a meteorite or a man-made
material like slag.
