You have radiometric data showing that accelerated decay has actually occurred? Please publish this as soon as possible.
Radioisotope ratios together with helium retention spells accelerated decay. There's no other possibility that I can think of other than de-accelerated diffusion!
And the diffusion data is nonsense. Do you realize that helium is produced constantly within the mantle and crust? Where do you suppose that He goes?
The surrounding He concentrations are taken into account in the work!
Please explain the method of 'starting and stoppping' accelerated decay.
See my comment to Mark24.
Also I am curious about the secondary effects of this accelerated radiation. If we have several billions of years of equivalent radiation occurring within one year, what do you think would have happened to life in the sea and on any vessel navigating it?
With the Recolonizatoion Model we're talking a factor 500 differnet.
How is that? What does He diffusion in zircons have to do with sedimentation?
It couldn't be simpler. If diffuison dating dates Paleozoic rocks at 6000 +-2000 years old wouldn't that suggest that the rest of the geo-column was created rapidly? He diffusion dating is not some obscure fact - it's a new dating method!!
I just looked at thousands of feet of a shale basin that covered a large portion of North America. How do you suppose this happenened? Care to change your statement?
Shales may be problematic for us - I don't know enough about it.
And why does cross-bedding, per se, indicated rapid deposition of an entire formation?
We're often talking cross-bedding for much of the way thorugh a formation - like through 12,000 feet:
F.J. Pettijohn Sedimentary Rocks 3rd Ed Harper & Row (New York) 1974
p520-521 "The stability or persistence of a particular paleocurrent system through time is indeed one of the most astonishing results of paleocurrent measurements. Cross-bedding in a 12,000 foot (3,660m) sequence in the Moine series of Scotland displays a uniformity of orientation throughout which was described by Sir Edward Bailey as "the most surprising single phenomenon" displayed by these strata (Wilson et al Geol Mag 90,377-387 (1953)). Pelletier (Pelletier et al Bull Geol Soc Amer 69, 1-33-1064 (1958)) has shown mean current direction to remain constant in strata ranging from Upper Devonian (Catskill) to Pennsylvanian (Pottsville) in age of Pennsylvania and Maryland. This means essentially stable paleoslope for a period of 150 to 200 milion years.
But not all are? What about the major inter-regional unconformities found throughout the geological record?
I would assign the major conformities to breaks between catastrophic layering.
So, you agree that ecological zoning doesn't work?
I agree that it is a big ask. When I was a Ecological-zoner I did seriously toy with the idea of post-Flood catastrophic innundations (due to my reading and your and other's posts) especailly since I prefer a post-Flood Pangea break-up for theological reasons.
You have to fit thousands of distinct dates, from billions of years equivalent radiation, into a 500 year time slot. The picture should be pure noise.
If the acceleration occurred over 500 years it's quite possible to exactly get what we see in the geo-col radioisotpoically. All you need is enough time for resetting. Resetting time is the issue your trying to address without saying it.
You have completely avoided the argument that there are concordant dates by different techniques and that this should be impossible. THIS is what you need to explain. Discordance is not an issue.
My presumption for now is that the metods we use are the ones which are largely concordant. Myabe some of the other methods that have been discarded are disconcordant for precisely the reason we propose.
