Even if you don't want to /can't afford buying thin sections to study, you can examine chondrules in "hand" specimens pretty well with simple magnification. I use a 20x triplet loupe similar to this one http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1215&item=6511994470&rd=1 and just recently bought one of these (though I got mine on Ebay for half that price) http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&product%5Fid=63-1133. I can't see individual crystals like you can with a thin section through a polarizing filter, but I can get a pretty good look at more obvious features-- fracturing, barred olivine, "pac-man" chondrules, and the like. ______________________________________________ Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
