Hi Mike and All,
Mike quoted, "So this horrible-looking meteorite has been laying around for
about
20,000 years, give or take."
I wouldn't call it, "horrible-looking", well at least not the 'blue' part of
the meteorite! In fact, it is pretty fun to cruise the surface under a
microscope! :)
Best Regards,
Greg

Thanks Phil. That is exactly what I was looking for. I had misplaced
the link to that article. I bookmarked it again. :)
So this horrible-looking meteorite has been laying around for about
20,000 years, give or take.
Best regards,

Mike, it's about as "old as dirt".
in the first paragraph at
http://www4.nau.edu/meteorite/Meteorite/Al_Haggounia.html
It states
The terrestrial age of samples of the bluish-gray material was determined
by direct measurement of carbon-14 by Dr. Timothy Jull at the University
of
Arizona Accelerator Mass Spectrometry Laboratory, and reported in an
abstract by Aoudjehane et al. (2009) at the 72nd Meteoritical Society
Meeting in Nancy, France. The measured age is 23,000±2000 years and
establishes this meteorite fall as occurring during the Pleistocene Epoch.
Does that help?

I hate to bring up Al-Haggounia again, for fear of starting the
aubrite-enstatite issue again. But, I have a question about Al-Hagg
that is unrelated to it's problematic classification.
Has the terrestrial age of Al-Hagg ever been firmly established? And
if so, how long has it been here on Earth?
