Hello Jeff and Lister I would have to agree with you more Jeff but I would take it further with the reign would say Semarkona is the only know 3.0 fall. No other 3.0 meteorite can beat that :) In addition to the fall it has under its belt, there are over 100 research papers done on the Semarkona meteorite.
Take a look at these two papers. First up... The Fine-Scale Cosmogenic History of the Semarkona Unequilibrated Ordinary Chondrite Craig, J.; Sears, D. W. G. http://www.lpi.usra.edu/meetings/metsoc2010/pdf/5055.pdf On the Use of Phase and Bulk Compositions in Classifying Chondrules from Semarkona (LL3.0) and Other Ordinary Chondrites Beckett, J. R.; Connolly, H. C., Jr. http://www.lpi.usra.edu/meetings/lpsc2002/pdf/1547.pdf Enjoy Shawn Alan IMCA 1633 ebay store http://www.ebay.com/sch/imca1633ny/m.html http://meteoritefalls.com/ ________________________________ From: Jeff Grossman <jngross...@gmail.com> To: "<Meteorite-list@meteoritecentral.com>" <Meteorite-list@meteoritecentral.com> Sent: Thursday, March 7, 2013 12:21 AM Subject: Re: [meteorite-list] finally: L3.00 Derek Sears, who gave us the first decimal place in his 1980 Nature paper (with a young me as coauthor), used to say that there was more chemical and mineralogical variation among the type 3 chondrites than among the type 4-6 chondrites. We now know that there is as much variation among the type 3.00-3.15 chondrites as there is among the 3.2-6 chondrites. It's kind of logarithmic, in many ways. Different things change at different temperatures, and on different scales. CO chondrites are less well characterized in this regard. Their finer grain size is a big part of the reason. The fact that there are relatively few of them, and that so many have properties that seem a bit anomalous makes their subdivision all the harder. So we don't have as many of them that have been finely classified.
