Re: why wiki may be a poor source
It's typical of popular accounts of Evolutionist and Old Earth conclusions: They do not bother with giving you any of their reasoning, it's only their conclusions stated as absolute fact.

"Absolute"? I don't remember that ever being the case.

Perhaps you overstate your position, or maybe you are simply projecting? If anyone is an absolutist around here, that would be you.

What is presented to the public is generally the current state of knowledge about the universe. I don't suppose you'd be as concerned if the 'six-day creation/global flood' story was presented as fact, would you?

I have read the RATE I and RATE II books. I've also read all the YEC "papers" that I know of on radiometric dating.

My sympathies. I could only take very small doses, confined to specific topics. Did RATE ever provide actual, positive evidence for a young earth?

Thank you for interpreting Mindspawn's posts.

As I already pointed out, the equilibrium to which you refer is billions of years in the future.

This link has some discussion about how secular equilibrium is handled in uranium exploration.

"In theory, secular isotopic equilibrium is attained in uranium deposits after approximately 1.7 million years if mineralization behaves as a closed geochemical system."

...

"Secular equilibrium is disturbed if the system is not closed. Uranium dissolved in oxygenated groundwater can be transported away, depleting the site."

Re: Interested
All 3 types of rocks, sedimentary, igneous and metamorphic have been known to form rapidly

They have also been known to form slowly.

And why is it so difficult to understand that fast processes do not indicate short time spans? Why can we not have a rapid process happening 100 my ago?

Re: Interested
I'm interested in the evidence for this - I can't seem to find much.

Well, it's not really a burning issue in geology. I can give you examples of rapid formation of each rock type, but they all require very specific conditions which don't control the deposition of the entire crust.

The Hawaiian Islands have been developing for tens of millions of years but any given rock body probably forms within minutes to thousands of years.

This is basically a stupid YEC argument.
