Hi Mendy and List,

You inquired:

"Can someone please clarify why this is listed as a Brachinite instead of
 diogenite? Based on the composition being 90% olivine, should this not
 be listed as a dunitic diogenite?"

Because igneous-textured brachinites are olivine-rich rocks (79-93 vol% olivine)
too. Looking forward to my little slice from Fabien and also looking forward to
looking at it under the microscope. Maybe the size of the crystals can shed a bit
more light on this "enigmatic puzzle"!

But, whatever it is, it is an achondrite and it is beautiful, ... and thin sections may
also be helpful in "solving" the riddle!

Best wishes,

Bernd
