[meteorite-list] AHL84001 strange passing thought.

[doctor death]

After reading the book review of the Rock from Mars I had a strange passing 
thought. I find it totally strange that this martian would be 4.5 billion 
years old unlike all the other martians most of which are more in the 
neighborhood of 1.3 billion years. But the atmoshperic isotopes check it out 
as a martian. But how do we know it wasn't a frag of the impactite that 
blasted the other martians into space. That would explain the xenon, etc. 
Must be an obvious answer in the evidence as this meteorite is probably the 
most carefully studied rock in history, but just made me think...
