It would be very interesting to find out what radiometric terrestrial dating methods will turn up with regards to NWA 482, a lunite. Thanks to Frank Cressy, I obtained a 2.162 g piece of this meteorite and it appears to be absolutely fresh. There is no weathering to be seen in the piece I have. But then again, the environment of North West Africa is very dry.
