Hello Listers, Its quite in here, I think people are having too much fun at Ensisheim. I am excited to see what meteorites people will have for sale, please tell :)
And for those of you that have some time to waist :) ..... I just came across this great research paper on the Egyptian beads made from meteorites. Its a good read and gives the reader on new perspectives on the use of meteorite in ancient cultures and anyone can download it for free. :) Shawn Alan IMCA 1633 ebay store http://stores.ebay.com/imca1633ny?_rdc=1 http://meteoritefalls.com/ AnalysisofaprehistoricEgyptianironbeadwithimplicationsfortheuse andperceptionofmeteoriteironinancientEgypt DianeJOHNSON1*,JoyceTYLDESLEY2,3,Tristan LOWE4, PhilipJ.WITHERS4, and Monica M.GRADY1,5 Abstract–Tube-shaped beadsexcavatedfromgravepitsattheprehistoric Gerzehcemetery, approximately 3300 BCE, represent the earliest known use of iron in Egypt. Using a combinationofscanning electron microscopy and microX-raymicrocomputertomography, weshowthat microstructuralandchemicalanalysisofaGerzeh ironbeadisconsistent with a cold-worked iron meteorite. Thin fragments of parallel bands of taenite within a meteoritic Widmansta¨tten pattern are present, with structural distortion caused by cold- working. The metal fragments retain their original chemistry of approximately 30wt% nickel.The bulk ofthebead ishighlyoxidized, withonlyapproximately2.4% ofthetotal bead volume remaining asmetal.
