Geologic History of North America Gets Overturned
Yahoo News ^ | 4-3-2013 | Becky Oskin

Posted on 04/17/2013 7:05:48 AM PDT by Renfield

t's time to redraw the map of the world during the reign of the dinosaurs, two scientists say.

Picture the U.S. West Coast as a tortured tectonic boundary, similar to Australia and Southeast Asia today. Erase the giant subduction zone researchers have long nestled against western North America. Drop a vast archipelago into the ancient Panthalassa Ocean, usually drawn as an empty void, the kind on which medieval mapmakers would have depicted fantastical beasts.

"Now it fits together," said Karin Sigloch, a seismologist at Ludwig-Maximilians-University in Munich, and lead study author. "We've come up with a pretty different solution that I think will hold up."

With a spectacularly clear look at the remnants of ancient subduction zones under North America, Sigloch and her colleague Mitch Mihalynuk have revised 200 million years of geologic history. The results of their study are published today (April 3) in the journal Nature....

According to this revelation, when a plate sinks well into the abyss of the earth’s core, down 1,200 miles; it retains some of the original structure it had when it was close to the surface. I would have assumed it would have been disolved by then.

The climate and typography assumptions of the Jurassic and earlier remain.

I think what they're looking at is the accretionary wedge at the upper limit of the subduction zone. What they are saying is that rather than than a single subduction zone along the margin of the NA plate, there was also westward movement (from the Juan de Fuca/Farallon spreading center) that accounted for another “left-handed” subduction zone further west that is now being overridden by the NA plate.

This has been a result of new discoveries, understanding, and modeling over the past decade or so.

I think it's pretty widely believed that subducted slabs are actually hitting the core-mantle boundary, astonishingly.

Personally, I think the expanding planet theory is too compelling to ignore.

Expanding Earth and Pangaea Theory

The center of the earth is a nuclear reactor, which is why it has never cooled down. Fission products are created by this nuclear reaction, resulting in an increase in volume as a single atom of one element decays and becomes multiple atoms of other elements.

Personally, I think the expanding planet theory is too hilariously stupid not to laugh at it or anyone that gives it any creedence.

There's no evidence the Earth is expanding based on GPS. There are thousands of pieces of evidence that subduction occurs, based on GPS and seismic profiling. Expanding Earth is garbage. Case closed.

I read a book once, so I’m pretty smart. I think the Earth is like a big tick, except that it doesn’t have to eat anything to get bigger. If you look at pictures of it from space it is round, just like a really big tick that is about to pop.

What is absolute BS is the notion that convective currents beneath the lithosphere move the continents. Ever wonder: what about Newton’s Third Law?

Yep. Once you’ve seen Neal Adams you can never go back. And when was it? Might it have been as it says in the Original Testament...in the time of Peleg, when the earth was divided, and the fountains of the deep were exposed...? (paraphrased.) The earth expanded within the memory of man, within historical times.

I don’t know if I buy all this. However, the apparent wash to the the east at the tip of South America, and at Panama is certainly interesting. North and South America have only been connected for about 3 million years. I have always felt as if my body wanted a 25 hour day, and I think others notice the same effect. So I certainly think an event affecting the speed of the earth’s rotation is possible.

I've read this one both ways. Speeding up and slowing down. The brain because of the physical world surrounding us believes in most reactions slowing after said action is a law of nature. It is the natural order to which each of us is exposed, till what was in motion comes to be at rest. In the world of time and space in the universe heard for countless years the expanse of the universe is slowing down only to next read and hear (oops) the expanse has not slowed. The entire discussion reminds me of the global warming theory. Global warming where we were told humans were cooling the planet about fifty years ago and a new ice age is coming. Then we were told, no, humans are increasing the rate at which the planet is warming and the ice is melting. Next we were told because things started to cool once more ... it's Climate Change. Have fun everyone. Lies and liars come in all aspects of life and science. I shall pray for God to control. Man has little to no control in this vastness called space.

It also explains how the parallel laid down rocks in my area are uplifted in a north westerly manner in parallel sinusoidal ridges.

Your link is no longer working so I can't go back and identify the most egregious contentions, but you still haven't provided me with your explanation for your statement regarding convection and Newton's Third Law.

Not sure what link you’re referring to, but the threeimpacts link is working. From that site I cited a paper that criticizes drift and convection. You said you read it and then classified it as garbage. I have asked you to elaborate why you classify it as you do. So: please explain why the paper by Lyustikh is garbage.

Sorry, but a 45 year old paper that can't even reference contemporary terminology is a poor substitute for modern research. If you really want (and if I thought it would do any good at all), I could supply you with some more up to date papers.

There are so many problems with this, I don't even know where to start - the author doesn't even have the decency to put his name on it! Not withstanding the grammatical errors, completely unsupported contentions, lack of any acknowledgment of well understood geological processes, the author can't even correctly identify the directional aspect of the Hawaiian Island chain. As far a “visual analysis” is concerned, that doesn't mean looking at Google Earth and guessing about stuff, it means applying known mechanisms to the problem at hand and developing comparable data to support a hypothesis. I really laughed when the author said he'd submitted his “findings” with Nature and the GSA - I wonder if he mentioned his view that a comet caused a global flood? Anyway, it's just crap.

If the earth is expanding, it's due to the slow build up of space dust and meteors continually hitting the earth.
