Implications of Polonium Radiohalos in Nested Plutons of the Tuolumne Intrusive Suite, Yosemite, California

by Dr. Andrew Snelling and Dallel Gates

Abstract

The formation of granite plutons has conventionally been thought to be a slow process requiring millions of years from generation to cooling. Even though new mechanisms for rapid emplacement of plutons have now been proposed, radioisotope dating still dominates and dictates long timescales for pluton formation. However, a new challenge to those long timescales has arisen from radiohalos. Polonium radiohalos found in biotite flakes of granites in Yosemite National Park place severe time constraints on the formation and cooling of the granite plutons due to the short half-lives of the polonium isotopes. The biotite flakes must have formed and cooled below 150ºC before the polonium supply was exhausted and the radiohalos could be preserved, so the U decay had to be grossly accelerated and the formation of the plutons had to be within 6–10 days. Furthermore, rapid cooling of the plutons was facilitated by the hydrothermal fluid convection that rapidly generated the Po radiohalos, challenging conventional thinking that cooling is a slow process by conduction. It is evident that there were greater volumes of hydrothermal fluids in the later central intrusions of the nested plutons of the Tuolumne Intrusive Suite. So as expected, more Po radiohalos were generated in these plutons as they were sequentially intruded, confirming the hydrothermal fluid transport model for Po radiohalo formation. Thus granite pluton formation is consistent with the timescale of a young earth, and accelerated radioisotope decay renders the absolute ages for these granite plutons grossly in error...

This one is technical...but very interesting IMHO

[GeronL]

um. *scratches head*

thats all scientology to me.

[GodGunsGuts]

Since you are sending me links, I thought I’d send you one :o)

[WayneS]

I traded all my plutons for candy and gum when I was a kid.

It’s one of the great regrets of my life. No more plutons for me... (SIGH).

[ClearCase_guy]

The biotite flakes must have formed and cooled below 150ºC before the polonium supply was exhausted and the radiohalos could be preserved, so the U decay had to be grossly accelerated and the formation of the plutons had to be within 6–10 days.

Well ... duh!

[GodGunsGuts]

I don’t blame you at all!

[Alamo-Girl]

Thanks for the ping!

[GodGunsGuts]

It’s like sooooooo obvious!

[Darteaus94025]

You know, I’ve been wondering about this for a long time.

[MHGinTN]

? placemarker

[GodGunsGuts]

I have a feeling you will still be wondering long after this thread has past :o)

Well du-uh.

[dforest]

When do I get to Obama in this um....article?

[calex59]

um. *scratches head* thats all scientology to me.

I am still trying to decipher the headline!

[papasmurf]

My hat’s off to you if your understand what you posted, I sure as heck don’t! LOL

[calex59]

If I had really been on my best game I would have said, “So simple a caveman could understand it!”.

[ken5050]

The REAL question is why did we all decide to open this thread and read it..???

[GodGunsGuts]

It is a monument to precisely where Obama does not want science to go!

“Implications of POLONIUM RADIOHALOS in Nested PLUTONS of the TUOLOMNE Intrusive Suite, Yosemite, CA”

Wha’d you call me?

[GodGunsGuts]

I saw halos, maybe the authors are calling you an angel :o)

[Dr. Ursus]

I understand and have a reply-Klaatu Barada Nikto

[dforest]

Can you break it down for me brotha?

[GeronL]

a caveman would have hit you on the head with a club -o)

[granite]

Definitely ABOVE my pay grade.

[TYVets]

I saw Radiohalos and thought they were talking about Rush during Holy Week.

My bad.

[TheOldLady]

Scientific proof of Creationism. Cool.

[FreeSouthernAmerican]

The author doesn’t know me very well then. HAHAHA. I try, but its unsuccessful most of the time.

[snarks_when_bored]

“The world could’ve been made 6,000 years ago. Really, it could’ve...I’m not kidding! Stop laughing! This is not a joke!”

[GodGunsGuts]

The superduper condensed version:

The Evos say granites take millions of years to form, these scientists present evidence that granites form VERY rapidly (i.e. years to tens of years).

[Petronski]

..more Po radiohalos were generated in these plutons as they were sequentially intruded, confirming the hydrothermal fluid transport model for Po radiohalo formation...

This ought to put the lie once and for all to all those blindered, stiffnecked, Philistine claims about non-sequential pluton intrusion.

[montomike]

This is like so....way beyond my paygrade!

[VRWCtaz]

Is this article about the stuff Bugs stopped Marvin from using to blow up the earth?

[editor-surveyor]

I don’t think that this is exactly new info.

I recall a discussion with a physicist from LRL Livermore, back around 1991 or 92, where he contended that the cooling had to have been complete in seconds, or the halos could not have formed.

[tumblindice]

“creationism”
No, no, no. It’s called `Intelligent Design’.

And I don’t go to the ‘hopper’. I visit my `Fortress of
Solitude’ where I sit and ponder matters of great import.

Like “plutons”.

[Clioman]

Nothing like a big bowl of biotite flakes to start the your day!

[editor-surveyor]

"When do I get to Obama in this um....article?"

That would be when he bows to kiss the Saudi king's plut-on...

[Nick Danger]

Big deal. We get nested plutons around here every Spring.

[editor-surveyor]

"Nothing like a big bowl of biotite flakes to start the your day!"

Very crunchy, and they never become soggy in the milk!

[tacticalogic]

The Evos say granites take millions of years to form, these scientists present evidence that granites form VERY rapidly (i.e. years to tens of years).

For this to be evidence of a young Earth, you have to disregard everything but granite, and find the same evidence in all the other granite.

[Zathras]

If it sounds stupid, it probably is.
The earth is NOT 4000 years old.

[DevNet]

He is saying this proves the Earth is only 6,000 years old.

[DevNet]

“so the U decay had to be grossly accelerated”

Notice the totally lack of evidence for accelerated atomic decay?

[pabianice]

I understood “of,” “and,” and “the.”

[dforest]

Thank you.

[Zathras]

I suspect the writer doesn’t even know where Polonium is on the Periodic Table.

[Jonah Hex]

I suspect the writer doesn’t even know where Polonium is on the Periodic Table.

Polonium is between Germanium and Ukranium and south of Scandium isn't it?

;-)

[MainFrame65]

The first paragraph discourages further reading, but I LOVE the title!

[techcor]

“Plutons” isn’t that what Mickey Mouse had to pick up after his dog had been in the yard awhile?

[TenthAmendmentChampion]

“The biotite flakes must have formed and cooled below 150ºC before the polonium supply was exhausted and the radiohalos could be preserved, so the U decay had to be grossly accelerated and the formation of the plutons had to be within 6–10 days.”

Stunning!
