This reported terrestrial age is even more of a problem for those researchers trying to prove that the weathered mineral grains in Lafayette were formed on Mars. One of "those researchers" is a fellow Listee and co-authored this paper: <http://www.lpl.arizona.edu/~bcohen/cv/pubs/iddingsite.html> And just to clear up any misunderstandings, I am not opposed to making Lafayette a fall. Quite the contrary. I'm just trying to define the obstacles that stand in the way of getting that status changed. The article above clearly proves that Lafayette is not related to Nahkla. This is a non-issue now. On the other hand, that same article lists all the evidence that stands in the way of changing Lafayette to being a witnessed fall. This evidence can't be ignored, nor dismissed out of hand. It has to be dealt with. A fellow Listee asked how does the status of a "find" get changed to a "fall". As it is with everything else, it's done through the "literature", and the evidence for it being a fall has to be published. My personal opinion is that, at this point, it would be easier to prove that a certain dog was "turned to ashes" in Egypt by a meteorite. To borrow a quote from George Bush Sr., "Naht gunna happen!" "Wouldn't be prudent." ;-) Bob V. --__--__-- Message: 3 From: moonrock25_at_webtv.net (Charlie) Date: Tue, 19 Dec 2000 10:02:03 -0500 (EST) To: mlblood_at_home.com Cc: mmorgan_at_mhmeteorites.com Subject: Re:[meteorite-list] Lafayette-a possible fall? Hi Michael, Thanks for your reply. Yes, I do recall that the witness heard, but did not see the fall. But I am wondering if a terrestrial age was determined. I thought it had been, and, inexplicably given the other "evidence", was in the many thousands of years. Perhaps others on the list will clarify this or correct my memory.
