Crash's science a bit shakey?
My "that's not quite right" detector has tingled over some of Crashfrog's postings before, but this is the first time I've responded. I'm not even quite sure what to say, other than I feel that the Frog's sometimes operating at the fringes of his/her knowledge.

And radiometric clocks only start counting from the time the stone became stone. So the age of the lime material has no bearing on the tested age of the limestone it forms. The clock is reset.
This is a bit muddled. Limestones are not (directly) radiometricly age dated. So there is maybe some truth there - maybe call it a half-truth (quarter truth?).
quote:
Remember the radiometric dating dates the time since the hardening of the stone, not the age of the matter itself.
See above comments.
Hypotheticly, one could have a quite recent sandstone, made up of very old zircons. That is, the zircons may have originally crystalized, say, 4 billion years ago. They would age date at 4 bya. But the sandstone might only be, say, 1000 years old.
Well, another crappy posting from -

I'll jump in here, Mark is certainly welcome to it also.
Not that I'm any great expert, but I find no fault with the quoted.
As I understand it, the living conditions on earth, for the dinosaurs et all, was in serious decline, even before the asteroid (or whatever) came crashing down. The impact only put a period onto what was already being a major extinction event.
So, esentially, the boundary was pretty well marked out, even before the Irridium clay layer was discovered.
Cheers,
Moose

An introduction to geologic methodology
Time once again to trot out my favorite introduction to geologic methodology page (covers more than just radionetric dating).
The outline of the page "Radiometric Dating and the Geological Time Scale":
quote:
* Introduction
* Background
--- Stratigraphic principles & relative time
--- Biostratigraphy
--- Radiometric dating: Calibrating the time scale
* A theoretical example
* Circularity?
* Specific examples: When radiometric dating "just works" (or not)
* Conclusions
* References
* Other sources
* Acknowledgements
Also, I rediscovered something I couldn't find a while back - a fairly good coverage of the KBS tuff dating problems (I don't recall if it was in this topic, that this was being discussed):
Specific Examples: When Radiometric Dating "Just Works" (or not)
Cheers,

Maintain your position in the face of incredible evidence that radiometric dating is mostly wrong.
You wish to make that "wrong" into a "right", I presume?
