[meteorite-list] Diogenite Nomenclature

[Greg Hupe]

Dear List Members and fellow diogenite enthusiasts,

I talked with Tony Irving this morning regarding the use of 'Olivine Diogenite' in classifications and abstracts. I have been enlightened to the ever evolving diogenite classification scheme. Seems a new 'pigeon hole' has been created due to new meteorites which are comprised of mostly olivine, the Dunite meteorites. Find below Tony's reply and link to an abstract that discusses their proposed, and more accurate separation of the Diogenite meteorites.

Best Regards,
Greg Hupe

[NWA 1877, NWA 5480 and other similar meteorites] would now be harzburgitic diogenites, but olivine diogenite is still OK as a general term.  The nature of nomenclature is that it evolves with the need to encompass new specimens, and we have mostly NWA and private collectors to thank for that.
