RE: Meteorite origins



Dear George,

The grammatical changes that I made on the letter were not meant to be rude or confrontive - I apologize for my misguided helpfulness.  I am not a scientist, but I thought I would try to help the community where my strengths are.  Again, I apologize.

Good  Luck and Best Regards,

Lawrence Linteau

In a message dated 06/04/99 13:04:28 GMT, you write:

<< This is my whole point. How do you know that it contains bubbles from
 the Martian atmosphere? The meteorite that contains those bubbles formed
 around 4 billion years ago. The atmosphere on Mars then was very
 different from the atmosphere of today. Therefore, how can you compare
 the two?   >>

4 billion years?
I thought the SNC crystallisation ages ranged from 2 million years up to 1.3 
billion years, but stand to be corrected on that. Remember that these are 
igneous rocks excavated from different depths, so they were molten at a 
comparatively recently when compared to others that we know originated from 
within the asteroid belt.
The trapped gases are not an exact match to the atmosphere tested by the 
Viking landers.....but they are very similar. The evidence is greatly stacked 
in favour of the SNC's originating from Mars, so confidence is high - but few 
scientists will declare that as 100% definite if there is even the tiniest 
amount of un-certainty.
Where else could these SNC's have come from if not the planets?...they are 
too young to be from the asteroid belt.

I'm convinced, but then I also believe in Nessie.....especially during the 
tourist season ;-)

Cheers,
Rob.
