Hi Jeff, Darren, and All, Ceratinly a most interesting find, and great news. I've been aware of this one since some months now, and all I can say that Darren's conclusions are way to the spot. The absence of solar noble gases indicates a VERY short transition time, and from what I've heard the researchers first doubted that it might be a meteorite at all. I'm sure that there will be a lot of most interesting publications coming up, pretty soon, that will answer all these question in great detail.
For now, all I can say is that I'm a bit sad that it will virtually be impossible to get a specimen of this whopper, and its smaller anorthositic sister. The finder is obviously intending to keep the entire masses, and to stay anonymous... Maybe there's a good part to that sad news, too, and that is that this whopper probably won't ruin the lunar market - for what it's worth... All the best, Norbert (still lunatic after all those years...) -----Ursprüngliche Nachricht----- On Fri, 13 May 2005 19:14:24 -0400, "Jeff Pringle" <[EMAIL PROTECTED]> wrote: >List - >Did anyone notice in the provisional Met Bull 89 that someone found a 13.5 KILO lunar in the Kalahari back in '99?

Even more interesting than the size (to me) is that "the sample does not contain solar wind implanted rare gases". Does that not mean that it had to spend a very short time "in transit" and would have to be from a recent impact? And have to be from a bit of a distance below the lunar surface, because any surface rocks would be exposed to cosmic rays? How short a period would the meteorite need to be exposed to space to not build up solar wind gases? ______________________________________________ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
