What a celestial beauty! A very unusual new discovery, not matched to any other known meteorite.

It is classified as a Ungrouped achondrite, norite, with a “cumulate intermingling of cream-colored plagioclase grains and vivid-green pyroxene grains. This meteorite contains approximately 60% plagioclase, 35% low-Ca pyroxene. Olivine was observed as small (~100 μm) inclusions in pyroxene. Metal is nearly pure iron with trace amounts of cobalt — nickel was barely detectable with the microprobe.”

I just procured this 122g central slice, ~6×7″ Curious if there is any more info on it out there.

One response to “The Center of Al Bir Lahlou 001”

  1. backside of end cut:Some detail of mine: And analysis from Carl Agee: "I classified it. Certainly worthy of further research, but the ungrouped is well established, not an HED. Plus very pretty!" Backscatter electron image of Al Bir Lahlou 001" Medium gray is pyroxene, dark gray is plagioclase. This is the intermingling of the two minerals, with blebby intergrowths. Small light gray with the pyroxene is olivine. Bright patches are metal. Scale bar is 100 microns.
