There are an additional two probable iron meteorite <DIV></DIV> <DIV></DIV>fragments, a 2-mm fragment recovered from the fines fraction of <DIV></DIV> <DIV></DIV>Apollo 11 regiolith sample 10085-18, and a 0.3x0.4-mm iron <DIV></DIV> <DIV></DIV>fragment from Apollo 16 regolith core sample 60014. Both Bench <DIV></DIV> <DIV></DIV>Crater and Hadley Rille were extensively heated when they impacted <DIV></DIV> <DIV></DIV>the lunar surface. This is reasonable because the peak in the <DIV></DIV> <DIV></DIV>relative velocity distribution of projectiles hitting the moon is <DIV></DIV> <DIV></DIV>14 km/sec. Less than 2% of the prjectiles survive as unmelted <DIV></DIV> <DIV></DIV>fragments. <DIV></DIV> <DIV></DIV>As far as nomenclature is concerned, most scientists refer to <DIV></DIV> <DIV></DIV>lunar material blasted off the Moon and delivered to Earth as <DIV></DIV> <DIV></DIV>lunar meteorites. Meteorites found on the moon don't seem to have <DIV></DIV> <DIV></DIV>a special label and are simply referred to as meteorites from the <DIV></DIV> <DIV></DIV>Moon. <DIV></DIV> <DIV></DIV>Alan Rubin <DIV></DIV> <DIV></DIV> <DIV></DIV> <DIV></DIV> <DIV></DIV> <DIV></DIV>______________________________________________ <DIV></DIV> <DIV></DIV>Meteorite-list mailing list <DIV></DIV> <DIV></DIV>Meteorite-list_at_meteoritecentral.com <DIV></DIV> <DIV></DIV>http://www.pairlist.net/mailman/listinfo/meteorite-list <DIV></DIV> <DIV></DIV> <DIV></DIV></div><br clear=all><hr>Chat with friends online, try MSN Messenger: <a href='http://g.msn.com/1HM1ENUS/c144??PS=47575'>Click Here</a><br></html> Received on Tue 27 Aug 2002 02:47:15 PM PDT |
