Thanks, Mark -- yes, that's a key bit of missing info! :-) The question remains, which particular petrology(ies) of Almahata Sitta contained the amino acids? Perhaps it wasn't in a ureilitic sample, but one of the main other breccia constituents, in which case the amino acids wouldn't necessarily have had the ureilite temperature history.
Thanks also to Martin, Anne and others who provided links to more scientific papers -- perhaps the answer to my question will be found among them. Happy New Year, All! --Rob -----Original Message----- From: [email protected] [mailto:[email protected]]on Behalf Of Mark Hammergren Sent: Thursday, December 30, 2010 1:59 PM To: Mike Hankey; meteoritelist; Robert D.Matson Subject: Re: [meteorite-list] NASA finds extra-terrestrial amino-acids inSudan meteorites The article is missing a description of the genesis of the asteroidal material. Almahata Sitta is a ureilite (among other things), which cooled from very high temperatures (in excess of 1100C) during its formation. -- Mark ______________________________________________ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
