[meteorite-list] [Announced June 8, 2010] NWA 5400: Earth-Related Meteorite

Hello Greg H I have also spoken to a scientist about NWA 5400 and for the meteorite to be ejected from Earth from the 4 billion Thea event, it would have to make the CRE at 4Ga, if its related to that event. Also, like you said, your not a scientist nor am I, but if you could, it would be

Shawn, It's a lot more complicated than that so we need to wait for this statement. I am willing to wait so there is nothing further to add at this point. Best regards, Greg - Original Message - From: Shawn Alan photoph...@yahoo.com To: gmh...@htn.net Cc:

Hello Kevin, I would let you know, that your book was the first meteorite book I had ever read. You inspired me to read Nininger´s Find a falling star. Since that time more than hundred books are following. So I can say, you have made me a meteorite book nut. Now time is come to reduce this

Re: [meteorite-list] [Announced June 8, 2010] NWA 5400: Earth-Related Meteorite

I think there is a misunderstanding on what the CRE dating represents. As Shawn pointed out, the abstract clearly states that The meteorite shows a large 129Xe excess (~3×10-10 cm3/g) derived from 129I decay (T1/2 = 16 Ma), indicative of its formation very early in Solar System history. That

Re: [meteorite-list] [Announced June 8, 2010] NWA 5400: Earth-Related Meteorite

The CRE age is the length of time this rock has been exposed in space to cosmic rays. That is, THIS rock, a chunk less than a meter or so, which the cosmic rays could penetrate (mostly) through. Now, if there was a 4 billion year old chunk that was fat enough, it would keep cosmic rays out of

[meteorite-list] Planetary Pairings...some facts, some guesses

Hi Martin, list, NWA 3163 IS paired with NWA 4483 and 4881 (Korotev Met. Bull.). All the other unpaired from your compilations are correct. This being and, on another note, because NWA 4483 was quasi certified having been found in Algeria (Ralew and also Met. Bull. database), I guess it is
