I minored in Geology, so most of my knowledge on the subject came from
hardcore geology texts. You might want to look in used book stores for the
Time-Life series on Geology. Not up-to-date, I'd imagine, but they are far
more involved than an encylcopedia. Continents in Collision (plate
techtonics and continental drift) from that series will probably speak of
the age of the earth and dating principles, but I'm not sure.

A range of 4 billion years, plus or minus a billion is pretty darn vague
beyond indicating the place is really, *really*, old. These are broad
estimates likely to be revised, and shouldn't be looked on as anything else.

Most people don't have the expertise one way or another to judge the
accuracy of these claims. That's actually what the creationists are banking
on - most people don't know how to question their claims. It's all about
creating plausible doubt, not scientific accuracy (on the highest levels -
I'm not saying Ryan is intentionally trying to mislead anyone. I presume he
is very sincere).
