[meteorite-list] New or maybe old QUESTION??????

Sun May 4 11:21:21 EDT 2008

Thanks Greg,  Beautiful photos!  Every  one interested in this material 
should check them out.  I like the slice of  "Blue" with an attached rhyolite 
pebble.   http://www.lunarrock.com/nwa2828/nwa2828pebble.jpg

It is one thing to  look at this material now with the knowledge of what it 
is.  I can only  call it astonishment when you cut into one like is shown in 
Greg's image.   But Greg,  what was it like to cut into a blue meteorite when it 
was  new!  I'm sure you had ideas of what it was but this was before any  
classification/analysis had been done.  What did you think when the first  blue 
meteorite was cut?

Hi Tom,  Pete and List,

Tom has been doing a fantastic job with his  studies and I thank him for his 
tireless efforts and for sharing with us.  Before the realization that NWA 
2828, Al Haggounia and the other pairings to  NWA 2828 were found to be an 
EL3 and NOT an aubrite, I spent many trips to  Morocco buying up the "Blue" 
material. Needless to say, I have several kilos  of the "Blue" EL3 material, 
one of the lucky first-in buyers, not price-wise  but material-wise :-)

Here are some additional photo links of NWA  2828 "Blue", most have seen 
these as they are the ones I have with my eBay  description of NWA 2828.
