Meteorite Classification



After Matt Morgans excellent post on the Iron Classes I dug up the 
classification chart I have been using curtesy of Phil Bagnall's book 
"The Meteorite and Tektite Collectors Handbook. I Contacted Phil (a frequent 
visitor here) and requested to post the classification I have been using by his 
permission. Phil was very generous and gave me the new second edition that will 
be published in the second addition of his handbook now being published and 
perhaps printing by William-Bell Inc. (also an excellent source of astronomy 
publications) Enjoy the chart.
