Dear List Members,
With my announcement of NWA 6704 yesterday, I received a couple of emails
from people who commented how it looks like a member of the HED group;
diogenite or olivine-diogenite. The lead specialist in classifying NWA 6704,
Tony Irving, put together this oxygen isotope chart with accompanying
description to help people visualize the differences. I hope this is
helpful!

"Oxygen isotopic compositions of various achondrites relative to the
terrestrial fractionation line (TFL).
NWA 6704 plots well below the TFL within the broad field for members of the
acapulcoite-lodranite clan,
and far from the fields for eucrites, diogenites and mesosiderites."
Best Regards,
Greg
