>> .. approx .. 4,566,500,000 years old
.. and it still amazes me that number ! It's always fun to blow peoples mind who are handling meteorites for the first time with : These rocks are [old]... 4,566,500,000 years Or 60,886,666 Human Lifetimes or 237,458,000,000 weeks or 1,662,206,000,000 Days or 39,892,944,000,000 Hours or 2,393,576,640,000,000 Minutes or 143,614,598,400,000,000 Seconds!

Hi L.A., Listees, Just the white powdery "CAI" material which represents a small fraction of Allende is the old snuff ... There are probably other carbonaceous chondrites of types similar to the "age" of Allende from the recent vast harvest of the deserts ... but I think scientists have a hard time splitting the hairs of the first couple of million years when they are just dealing with excess concretes that never were cleaned during the construction of this whole cool neighborhood of the Sun we live in. Bjurbole is a standard and older than the hills of the Solar Sytem, as well ... at least a standard to judge others: the oldies must all be aroound 4,566,500,000 years old. or maybe a million more. Telling the age of a meteorite is kind of challenging since they are heterogenious. For example, a person is born and grows based on an initial splitting of some strands of DNA. But if someone analyzed the ends of your hair, the might find you older than all the men on the list except Bob Haag and Ken (?), and Michael C. So how many inclusions floating out there in places no one expects, I couldn't guess ... that are older than old. Then, several listmembers may be older and know better, Best wishes and nice to see you posting, Doug -----Original Message----- From: Leigh Anne DelRay <[EMAIL PROTECTED]> To: [email protected] Sent: Tue, 15 Apr 2008 2:22 am Subject: [meteorite-list] what is the most primitve meteorite? or do we even know? Dear Listees~ I was wondering if anyone knows what the oldest (as in most primitive) meteorite is? I was thinking it was Allende, b/c it is believed to be of extra-solar origin, but is there another one that is more primitive than that? Is there one that is older than our own solar system? Thanks for letting me pick your brains. ~L.A. DelRay ________________________________________________________________________ _ ___________ Be a better friend, newshound, and know-it-all with Yahoo!
