  In Nov 2004 the news of potential new Colorado lunar was published to
the List. Checking the chemical analysis from the abstract
(http://gsa.confex.com/gsa/2004AM/finalprogram/abstract_76183.htm)
Allan Treiman quickly alerted the List that there was a problem. (see
email below) Allan was right. Randy Korotev added that not only was it
not a lunar meteorite, "I suspect that this object is a piece of
industrial slag."
(http://epsc.wustl.edu/admin/resources/meteorites/granada.htm) On one of
his websites, Neil Ray apologized for "for any misunderstanding or
confusion that my published abstract has brought about." You would
think this would be the end of the matter, but it is not.

Perhaps you have seen the eBay auctions "Chicxulub meteorite (0.xxx g)
comes with COA/ guarantee
very rare, meteorite that wiped out the dinosaurs, NR!" (ex.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=6601599997) Well
guess what? It is the same 'lunar' material (Granada) resurrected by Mr.
Ray to a new and more prosperous life.

Initially I wrote Mr. Ray about his use of the the term 'meteorite' in
his eBay auction title.
(http://home.earthlink.net/~ebaywrong/auction/Chicxulub.html ) He
refuses to change "Chicxulub meteorite" while at the same time admitting
it is not a meteorite? (more 'misunderstanding or confusion') I thought
he was legit, and then I looked at his research conclusions.
(http://www.chicxulubmeteorite.com/) Making this short, I disagree with
his conclusions.

And what would Allan Treiman have to say about the new theory? Well, I
asked him. He said, "The simplest explanation, with the data I have, is
that Mr. Ray's rock is a piece of EAF slag." (EAF stands for Electric
Arc Furnace).
