Correlation Among Various Radiometric Ages

http://EvC Forum: Age Correlations and an Old Earth -->EvC Forum: Age Correlations and an Old EarthPercy has a table there with more than a little bit of what you're asking about. And it's only the old stuff - Mark24 has posted a more recent (K-T boundary) set of examples here as well. There are too many possibilities to search through for me to find it, but Mark, if you're around...?

Then what, pray tell, are these methods used to date? The hard things people dig out of the ground are very often known as "rocks" in English, and are the things mentioned in those links! What are you on about?Edited by Coragyps, : typo

You've sort of mentioned potassium-argon dating here. Would you like to learn a little about uranium-lead, uranium-thorium, thorium-lead, samarium-neodymium, rubidium-strontium, or lutetium-hafnium dating, too? Or one of the other methods that all the correlations spoken of here are built on?We can learn you up if you'd like.....

We don't have an instrument that "directly measures" silicon, or oxygen, or iron in a rock either. That hardly keeps some smart people from figuring out ways to measure them.Of course there's no age-meter for a rock. It's nice, though, that there are direct counts of age for trees, or lake bottoms, or glaciers. All of those lead to an earth way over the 6000 years YEC's like.

Elephants have never been known to barf significant quantities of samarium-147, so I don't see the significance here, no.You have no idea what I'm even talking about, do you, JF?

None known to the poster using the name "Jesus Fighter," that is. He's been reading too many creationist websites to learn of any.Tree rings.
Lake varves.
Ice varves.
Ocean-bottom varves.Those are ones you yourself could count, JF. No tools required.
