I had a nice evening chat with Dr. Ruzicka a while back, this paper is the
completion of a very long endeavor. He is very erudite and enthusiastic on
the subject and I am glad to see the finished work. Portales Valley deserves
it.

> 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.
