NWA 6470, anorthositic regolith breccia

This wonderful meteorite is comprised of mostly vitrified 4.3 billion year old Lunar highlands regolith.  This meteorite started out as mostly white/light grey rock, but most of it was melted into black glass by asteroid impacts on the moon.  It’s a complex breccia with at least three major lithologies and a few larger basaltic clasts.  It even has a few unusually large (for a Lunar) ~mm-sized metal grains entrained in the lighter-grey lithology — metallic remnants of iron-rich impactors on the surface of the Moon!

Back when this meteorite was found, circa 2007, dealers selling pairings offered it as “the Apollo 16 Lunar,” because it was chemically and texturally similar to samples collected by astronauts at the Apollo 16 landing site.  See Randy Korotev’s page on this find, here.
