This Enstatite 'conversation' reminds me of the 'ongoing need' to make the proper [Official Classification] changes to Al Haggounia (aka earlier, NWA 2828). The 'Official' classification which has been proven NOT to be an Aubrite needs to be corrected in the Meteoritic Bulletin and other public places. Al Haggounia is a 'simple' EL3-6 meteorite which makes it pretty interesting in its own right. This is one that has been pushed aside by the committee and ignored even though Drs. Irving, Bunch, and others have proven over the last several years it is a unique Enstatite Chondrite... Not an Aubrite! Here is an in-depth web page that discusses the problems with Al Haggounia/NWA 2828 and pairings, a VERY good read for all who seek the truth about this unique 'Enstatite'... >From Northern Arizona University (NAU) & the University of Washington (UW): 'The Al Haggounia "Fossil or Paleo" Meteorite Problem' http://www4.nau.edu/meteorite/Meteorite/Al_Haggounia.html Best Regards, Greg ==================== Greg Hup?

Since it's a joint NIPR-Belgian meteorite find, it will never show up on the private market anyway. I was waiting for Jeff to chime in on this one and clarify the apparent new class. With the sample being so small, and with the differences between the classification peculiarities between different institutions, I assumed it was a temporary classification - put the meteorite under some heading until we figure out later where it properly fits into the scheme. I also left out the word "breccia" by mistake. The actual classification in the Bulletin entry is "E-Melt Breccia". Thanks for the clarification Jeff. Now I can go back to chasing more-obtainable "unobtainables" like a Kakangari specimen. :) Best regards, MikeG -- ------------------------------------------------------------- Web - http://www.galactic-stone.com Facebook - http://www.facebook.com/galacticstone Twitter - http://twitter.com/galacticstone Pinterest - http://pinterest.com/galacticstone ------------------------------------------------------------- On 6/7/14, Jeff Grossman via Meteorite-list <meteorite-list at meteoritecentral.com> wrote: > I wouldn't get too excited about this.
