I know about this one. The mineralogy and chemistry was done by a team of scientists that incuded one who I met at a seminar( a guy named Zare of Stanford). He was assigned to put together a chem /mineral description of this meteorite (which had been deduced to be a "Strewn chunk" from a bolide hit on MArs and theis meteorite was some of the debris.
What looked like biogenic stuff wound up having mineralogical assemblages called "Carbonatites"[Bell, Keith,1989,Carbonatites, genesis and evolution. Kenwyn inc
] which can result from a quick heating and cooling and the formation of "blebs" which look like pasta and the mineralogical significance is that all of the carbon was C13 (non living) and that the xl formation of the carbonatite mineral body was unremarkeable. The panspermists have tried to keep this going since th early 90's (when it was discovered). Their contention is that life was centered within the SOlar System and had been transferred planet to planet after one planet was hit from deep space with a life carrying meteor. Its still a working hypothesis but this meteorite doesnt support the story.
I wonder what the Creationists have to say about the 52 new life zone planets that re discovered in a 0.005% ar second segment of space that Kepler found. It appears that there are an unimageanable number of life zone planets out there .
I heard Garrison Keihlor muse this weekend that
"Whay would many citizens ofthis planet be so insistent that their God had sent his son to just one insignificant planet out of the huge maze of planets with possible life on them?"
Wed seem to be deluged with counter science websites lately. What the hell, its still fun and games no matter what we find out.
