[meteorite-list] Sahara 99555, a "Rosetta Stone"!

[luc Meteorites.tv / Labenne Luc]

Hi List,

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”

Baker and Bizzarro are now able to show that achondrite planetesimals formed 
before chondrite planetesimals.
