Generally try to find as many pictures of slices or interiors of meteorites as you can find (NWA slices usually are the best for ID'ing similiar meteorites like you have) And really just try and compare them to the picture of one that is already classified. Your might not be right on but you probably could have a good idea of what you have. The only way to be really sure would be to take a small piece (bout the size of a fingernail) and send it off to a university or museum and they could ID it there for sure. I dont know if the Geological Survery of Canada does it seeing they are only really interestred in Canadian meteorites.<BR><BR></P></DIV> <DIV></DIV> <P>Clear Skies & Happy Hunting,</P> <DIV></DIV> <P>Jay Haynes</P> <DIV></DIV> <P>IMCA Member #:6905</P> <DIV></DIV> <P><A href="http://www.geocities.com/cdnastronomer/meteorite.html">www.geocities.com/cdnastronomer/meteorite.html</A></P> <DIV></DIV> <DIV></DIV> <DIV></DIV> <DIV></DIV> <DIV></DIV> <DIV></DIV>>From: "Graham Christensen" <MAJORVOLTAGE_at_HOTMAIL.COM> <DIV></DIV>>To: Meteorite-list_at_meteoritecentral.com <DIV></DIV>>Subject: [meteorite-list] Classifying meteorites. HELP! <DIV></DIV>>Date: Sat, 13 Apr 2002 01:10:07 -0600 <DIV></DIV>> <DIV></DIV>>Hello list, <DIV></DIV>>I haven't posted in a while, I have been busy with school work and I <DIV></DIV>>just <DIV></DIV>>got my report card (81% in physics :). I just got a whole bunch of <DIV></DIV>>unidentified meteorites from Northwest Africa that were sent to me <DIV></DIV>>by Simon <DIV></DIV>>de Boer (Thanks again Simon :) and I want to try classifying them. I <DIV></DIV>>need <DIV></DIV>>suggestions/tips/general rules about how to identify them. I am <DIV></DIV>>pretty sure <DIV></DIV>>they are all ordinary chondrites, they all have metal flake and <DIV></DIV>>chondrules <DIV></DIV>>except for a few badly weathered ones. Are there any keys for <DIV></DIV>>meteorites <DIV></DIV>>like there are for identifying insects and plants? Many of them <DIV></DIV>>don't look <DIV></DIV>>like any of the ones in my collection and photos on the internet <DIV></DIV>>don't show <DIV></DIV>>the fine details so I really have nothing to compare them to. I have <DIV></DIV>>some <DIV></DIV>>guesses on some of them but I would rather go about this <DIV></DIV>>scientifically. One <DIV></DIV>>of them has a few giant chondrules or inclusions in it. And one has <DIV></DIV>>so much <DIV></DIV>>metal in it it almost looks like a mesosiderite but with chondrules. <DIV></DIV>>A few <DIV></DIV>>of them have armoured chondrules, those are really neat. Any <DIV></DIV>>information <DIV></DIV>>would be greatly appreciated. <DIV></DIV>> <DIV></DIV>>Thanks. <DIV></DIV>>************************************************************ <DIV></DIV>>Graham Christensen <DIV></DIV>>majorvoltage_at_hotmail.com <DIV></DIV>>http://www.geocities.com/aerolitehunter <DIV></DIV>> <DIV></DIV>> <DIV></DIV>>_________________________________________________________________ <DIV></DIV>>Chat with friends online, try MSN Messenger: <DIV></DIV>>http://messenger.msn.com <DIV></DIV>> <DIV></DIV>> <DIV></DIV>>______________________________________________ <DIV></DIV>>Meteorite-list mailing list <DIV></DIV>>Meteorite-list_at_meteoritecentral.com <DIV></DIV>>http://www.pairlist.net/mailman/listinfo/meteorite-list <DIV></DIV></div><br clear=all><hr>Chat with friends online, try MSN Messenger: <a href='http://g.msn.com/1HM501601/z'>Click Here</a><br></html> Received on Sat 13 Apr 2002 11:03:22 AM PDT |
