Mag.)       #2663346 - 09/25/08 08:55 PM Edit   Reply   Quote Quick Reply   The November issue of Astronomy Magazine arrived in today's mail. The cover has a small photo with the words, "Rare angrite meteorites may have come from Mercury, p.32". Have not read it yet, but the photos and graphics are very interesting at a glance. Looking forward to everyone's commentary. All the best, Mark J.D. Post Extras:       csa/montana Astro Ambassador Reged: 05/14/05 Posts: 28270 Loc: montana Re: Another Article on Meteorites (Astron.

Meteorite prices fluctuate like wind direction. Have you tried combing other sources besides eBay?

[Re: Veridian]       #2670477 - 09/29/08 04:59 PM Edit   Reply   Quote Quick Reply   Hi Mark, A paper I read in a recent issue of Meteorite Magazine (by a respected researcher) all but shoots down the angrite-Mercury connection. I was on the fence before reading the article, but after reading it, I would bet against any Mercury-Angrite connection. I wish there was, since it would make my Angrite micromount more interesting and valuable to me. Meteorite Magazine (Volume 14, #2, May 2008) - "Do Angrites come from Mercury" (page 7), by Melinda Hutson. Melinda Hutson is a Research Assistant Professor at Portland State University and is curator of the Cascadia Meteorite Laboratory collection. Her article is well-written, definitive, and contains a slew of academic references to the latest research on the subject. In short, her article casts very serious doubts on the Mercury connection.

Although I have not read it in depth yet. It's always nice to see meteorites getting some press. Personally, like I said above previously, I am in the camp that does not believe angrites come from Mercury. The evidence is just not compelling and is full of holes. I would say it is "possible" that angrites may eventually be proven to come from Mercury or a Mercury-like parent body, but much more research needs to be done to prove this. Regardless of whether they come from Mercury or not, angrites are a very rare type with some unusual properties. They are still very interesting from a collector's standpoint and from a scientific standpoint.
