>> Hello List,
>>
>> Well for years now, I know a lot of us were puzzled
>> by the classification of Portales Valley as an " H6
>> ordinary chondrite". (See my article in the May 2001
>> issue of Meteorite, titled " Portales Valley - A Not
>> So Ordinary (Ordinary Chondrite??)! " In the recent
>> past, the classification was modified a bit, being
>> changed to read as an " H6 Impact Melt Breccia ".
>>
>> I am excited to be able to say that there is a
>> distinct chance the true uniqueness of PV may soon be
>> reflected in a possible new moniker for this
>> intriguing meteorite. David Weir was kind enough to
>> make me aware of a new and comprehensive paper by Alex
>> Ruzicka, Marvin Killgore, David Mittlefehldt, and Marc
>> Fries in the current MAPS. In this detailed work, we
>> now have the proposed reclassification of PV as an "
>> H7, metallic-melt breccia (primitive achondrite)",
>> with the case made for a new meteorite type
>> designation of "Portalesite" due to this metallic-melt
>> breccia characteristic.
>>
>> You can read David's updated description of PV on
>> his excellent website here:

>> Many thanks to David for news of this exciting
>> paper, and to the authors of the paper as well.

>> Sincerely,
