if it's an antiquated term, what is it called now?

I'm not sure at all it is an antiquated term, it is listed in the GeoWhen database too. And what is more important, it is not part of the Proterozoic eon. Archean is an _eon_ of its own, as well as Hadean and Phanerozoic. That should be mentioned in the article. Jyril 22:00, 9 Jul 2004 (UTC)


The Tree of Life link is not very good -- it goes to a religious article. Falatwar

[edit] Percentage of cratons of Archean age

Question: "...7% of the Earth's cratons formed during the Archean" --Does anyone have a value for the percent of continental outcrop/surface rock that is Archean? Or is that what is meant? Fantastic referencing, btw, thanks. Andesite 22:56, 11 January 2007 (UTC)

Good question - I spent some time trying to find a validation or explantation of that figure, and could not; perhaps someone who has access to the Stanley book can do so. My guess is that the 7% figure refers to some estimate of the actual extent of Archean vs other rocks, and that the amount of outcrop of Archean rocks would be even less. But I definitely do not know for sure. Cheers Geologyguy 00:13, 12 January 2007 (UTC)

[edit] Origin of word?

What is the origin of the term "Archean"? I really want to konw. —Preceding unsigned comment added by 76.102.227.227 (talk) 00:08, 12 February 2008 (UTC)
