[meteorite-list] AD : The oldest rock on Earth : 4.28Ga !!!

[Fabien Kuntz]

Hello, 

a last AD for now, few slices of a paraggneiss called "faux-amphibolite", the 
oldest rock known on Earth, with an age of 4.28 billions years old! A Hadean 
crust relic (with possibly Late Heavy Bombardment evidence, based on Os isotopes 
arguments).

I obtained samples directly from the team published it in Science (26 SEPTEMBER 
2008 VOL 321). An agreement on a trade (with meteorites of course), and when 
they collected during 2009 field work new specimens of garnet-bearing 
"faux-amhibolite" (4.28Ga), cummingtinite-rich "faux-amphibolite" (4.28Ga), 
Banded Fe-Formation (3.8Ga), Fe-rich amphibolite (4.02Ga) and Fe-rich garnet 
amphibolite (4.02Ga) for more studies... some was for me (with all field data)! 


Few specimens sold in Ensisheim, I have here new slices of the garnet-rich 
"faux-amphibolite" lithology available (and a link to download the full thesis)

Other lithologies uppon request, include the 3.8Ga BIF (first evidence of 
microbiological life on Earth, as other the other BIF of the same age around the 
world).
