Hello Martin and All, http://www.meteorite-times.com/Back_Links/2009/august/Accretion_Desk.htm
It’s nice to see a witnessed iron on the Accretion Desk this month. It is quite easy to forget that witnessed iron falls are incredibly rare. In fact, according to the MetBull database, witnessed HED’s are more abundant than irons at ~69 witnessed HED achondrites to ~49 witnessed irons. Even at that number, iron falls are so highly prized by museums and institutions, that you are lucky to find anything outside of Sikote-Alin, Udei Station, or the occasional Boguslavka or Braunau. I was surprised to see that Martin’s piece has a ‘hack-saw’ cut job – something I thought was unique to my piece of Bogou: http://img.villagephotos.com/p/2004-11/877141/Bogou-3.jpg I purchased my Bogou several years ago (ex. Cureton Collection) sight-unseen and re-etching and cutting off the hack-saw marks and 'hanging chads' has always been on my to-do list until I read Martin’s article. It is easy to forget that those blemishes can actually help tell the story and human interaction involved with particular specimens. In fact, I think a hacked-up Bogou looks just fine now ☺ Martin also reminds us of how delicate and rare -real- fusion crust on an iron is. On Bogou, it is like the thin crust of a croissant and can easily flake off if not handled properly: http://img.villagephotos.com/p/2004-11/877141/Bogou-2.jpg Finally, the ‘good’ side, showing the curvature of the specimen. One can only imagine how impressive a full slice would be: http://img.villagephotos.com/p/2004-11/877141/Bogou-1.jpg Martin, I wonder if our specimens shared a jar with the Cureton Collection? 6 Irons Old, Mike Bandli ______________________________________________ http://www.meteoritecentral.com Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
