[meteorite-list] AD - Rosetta Stone Pieces

[Peter Marmet]

Dhofar 908...Rosetta stone?

For many years that expression was used for NWA 99555:

A very important new paper on our angrite SAH99555 (Sahara 99555, a  
2710g single stone with black fusion crust found by our team in May  
1999) was published in the last issue of the scientific journal  
Nature. In the words of co-authors Joel Baker, Director of Geology  
School of Earth Sciences, University of Wellington, NEW ZEALAND, and  
Martin Bizarro, Leader, MC-ICP-MS Laboratory, University of  
Copenhagen, DENMARK : “Your angrite meteorite find SAH9955 is now the  
oldest absolutely dated igneous rock in the Solar System, has clear  
evidence for the former presence of short-lived 26Al in it (which  
caused planetesimal melting), and very likely will become the  
"Rosetta Stone" for early Solar System chronology”...

Will every a bit special meteorite be nicknamed "Rosetta Stone" now?

To my knowledge Dhofar 908 is paired with  Dhofar 302, 303, 305, 306,  
307, 309, 310, 311, 730, 731, 489, 908, 909, 911, 950, and 1085...
It seems that Dho 908 has something that all those others do not  
have. This is very interesting and I'd be very pleased to know more  
about that phenomenon.
Thank you!

Peter
