So now we have to believe that all the high mountains were created AFTER the flood?

Oh look, there's a mountain growing outside my window at over 1 foot per year. Why don't you all come over to look at it? But if this is such a common occurrence I am sure you all can see your own mountains growing every year.

Hi Deist,

The answer to this question is dependent on just how flat (uniform) you believe the surface of the Earth might have been.

Let's take an extreme example just to illustrate the point: Suppose the crust of the Earth were completely, uniformly flat. If that were the case, then water would be the next lightest material (after dirt/rock and before air) and even a tiny amount of water would cover the entire surface of the earth. The entire volume of liquid water would be spread evenly over the entire globe and every square inch of land would be under water.

When RL suggests that mountains might not have been as high, he may also be implying that ocean trenches may not have been as deep, and difference between the rise of a continent and the depth of the ocean may have been more uniform.

I don't think it makes any sense to try to address RL's vision of water covering the surface of the earth until you get some reasonable understanding of how how he envisions the uniformity of the planetary crust. And you're never going to get details like that from RL.

Do people actually believe that? Serious.

I remember going to Sunday school and watching cartoons on Noah's ark. There were big mountains etc, and when the water went down, the ark was on top of a big one.

I guess out with the old in with the new. That old tape much be concidered heresy now. If the churches were smart (If the churches were smart...) they would have replaced the VHS when the big shift to DVD happened.

It is possible that the ocean beds may not have been as deep, although I have not relied on that possibility.

I simply stated that there IS evidence that many of the high mountain ranges were at one point underwater, as shown by coral, sedimentary strata, etc; and that there is good reason to think that all of the continents may have been basically one landmass instead of many widely separated ones. Both of these factors make it much easier for the entire earth to have been submerged.

We can all agree that this is so, what we may DISagree on is the timing.

That is why it is important for the unproven assumptions that underlie most dating methods to be understood.

Structures of KNOWN recent origin are 'dated' as millions of years old. Something wrong there, y'know?

Taken from a John Christie article on the web:

Now any radioactive isotope decays with a fixed half-life. If it has a half
life of 1 day, then at this time tomorrow only half of it will be left, only
one quarter the next day, and so on. After 10 days there will only be one
thousandth of the original amount, one millionth after 20 days, one
billionth after 30 days, and after 50 days, you can forget it!

Here are some category 1 isotopes that are abundantly present on earth:

uranium-238 has a half-life of 4.51 billion years
uranium-235 has a half-life of 0.71 billion years
thorium-232 has a half-life of 14.1 billion years
potassium-40 has a half-life of 1.28 billion years
There are about 6 or 8 others, all with half-lives greater than that of U-
235.

ican, You can't continue to base your assumptions on a single proof for the age of this planet. You must look at "all" the current evidence available. The above article presents some of them, but science looks at everything that supports the estimated life of earth.

It's not as simple as us all agreeing that every where was once underwater, and it was a matter of figuring out a date. we'd have to additionally agree that the evidence suggested that everything was underwater at the same time. Sure a mountain may have coral on it, but if it used to be the sea bed... of course it has coral! It doesn't mean that it was the sea bed at the same time some other location has sediment etc.

There is not enough water to support a flood theory, nor any other evidence to substantiate.

Of course. We already know that some mountain ranges are driven up by plate tectonics. The himalayas are one example.

Yes, the continents were once a single supercontinent. Actually, I think it happened several times. Pangaea, Gondwana...

How?

How does the fact that mountain ranges can rise from plate collisions, and continents can all merge make it easier for the entire earth to have been submerged?

In NA there's evidence of at least 3 supercontinental assembly episodes. In the Pacific (since all the past supercontinents faced the sea, their area assemblies are maybe even more(not sure how recent evidence is interpreted as of yet).

The method of age dating supercontinental collisions is by a technique based on "Wilson ccycles" and we look at "mantle depletion" rather than age dating crustal rocks (since crustal sedimentary rocks collect and incorporate all ages of previous supercontinents.
The most useful isotopic method for mantle depletion analyses is Samarium/neodymium age dating.

The supercontinents , from the earliest at about 2.2 Billion years was COLUMBIA, then RODINIA and lastly PANGEA.
So, to complicate RL's life, we have very good evidence of mantle accretion events of continents banging into each other and mountain building and erosion, at least 3 times since his Flood.(this, using his logic)
Based on the evidence then, some wag in the Canadin geo survey, AAUMING THAT THERE WAS A fLOOD, computed a Wilson cycle continental drift speed of about 7 miles per hour.
Hell , if that were true, C.I. wouldnt have to buy plane tickets to do his globe hopping. He could just find a nice piece of real estate and cruise on it. Cool

Right now, if 7 mph isnt too slow ci, your next Alaskan junket could be taken by just taking a hotel room at the Transamerica in SF and wait till the plate winds up in Anchorage in about , lessee 7mph , about 2000 mi. CI would get to Anchorage from SFin about 12 days, by hitching a ride on Cunards" Pacific Plate Tectonocruise" Lines. . lotsa no evidence to support rl's flood story.

One can assume anything.

However, if a continent traveled even a large distance, say 5000 miles over a very short time, say, a hundred years, then you are only looking at 31 FEET per hour.

Not quite the 7 MPH that you like to have fun with, but hey, continue to have fun with it. No prob.

One can assume anything but one can only observe what is readily visible. I don't see the continents moving at any high rate of speed. Nor do I see how they could have sped up or slowed down without some force being exerted on them.

To claim that at sometime in the past the continents moved at a faster pace is an assumption. An assumption that can't be supported with any real science or math.

whereas the plate motion from mid ocen ridge to land CAN be cleverly age dated by isotopic ages and we can see that evidence shows a fairly constant speed of about 200 cm per hundred years on each side of a mid ocean ridge,

What the Canajun did , Real life, was to assume like he were a CREATIONIST, and that all these tectonic events were post flood , since no ocean sediments are stuck uniformly to mountain massifs. so your "ocean sediments" would have had to be broken up by m ountain building , not be contemporaneous with inundation. See, you cant have it many ways rl, our logic either rises or falls with our evidence

True; even the last oceanliner I took from Rio to Barcelona last month at a speed of 18 knots took only five days from land to island.

Thank you for beging specific with an example.

Now please be specific about which pieces of evidence regarding Mt. St. Helens you believe are in conflict regarding dates and ages.

Thanks,

Mt St Helens.


I assume this is what he is refering to.

In the case of Mt. St. Helens an individual named Dr. Steven Austin used potassium-argon dating to date the lave flow at Mt. St. Helens, as well as other volcanoes.

The following is from the Creationist website;
http://www.creationism.org/articles/swenson1.htm

Quote:
The concept of radioisotopic dating is fairly simple. The method used at Mount St. Helens is called potassium-argon dating. It is based on the fact that potassium-40 (an isotope or "variety" of the element potassium) spontaneously "decays", becoming argon-40 (an isotope of the element argon). This process proceeds very slowly at a known rate, having a half-life for potassium-40 of 1.3 billion years. In other words, 1.0 gram of potassium-40, in 1.3 billion years, would decay to the point that only 0.5 gm was left. Theoretically, given certain assumptions, one could measure the amount of potassium-40 and argon-40 in a volcanic rock sample and calculate how old the rock is. When this is done, the age is usually very great, often millions of years.

In June of 1992, Dr. Austin collected a 15 lb. block of dacite from high on the lava dome. A portion of this sample was crushed, sieved, and processed into a whole rock powder as well as four mineral concentrates. These were submitted for potassium-argon analysis to Geochron Laboratories of Cambridge, MA, a high quality, professional radioisotope dating laboratory. The only information provided to the laboratory was that the samples came from dacite and that "low argon" should be expected. The laboratory was not told that the specimen came from the lava dome at Mount St. Helens and was only 10 years old. The results of this analysis, shown in Figure 2 (below), were recently published.1


Sample (Mt.St.Helens' new dome) "Age" (in millions of years)
1. "Whole Rock" 0.35 ± 0.05
2. Feldspar, etc. 0.34 ± 0.06
3. Amphibole, etc. 0.9 ± 0.2
4. Pyroxene, etc. 1.7 ± 0.3
5. Pyroxene 2.8 ± 0.6

-------------------------------------------
Figure 2. Potassium-argon "ages" for "whole rock" and mineral concentrate samples from lava dome at Mount St. Helens.
What can one observe about these results? First and foremost is simply that they are wrong. A correct answer would have been "zero argon" indicating that the sample was too young to date by this method. Instead, the results ranged from 0.35-2.8 million years! Why is this? A good possibility is that solidification of magma does not reset the radioisotope clock to zero. Probably some argon-40 is incorporated from the start into newly formed minerals giving the "appearance" of great age. It should also be noted that there is poor correspondence between the different samples, each taken from the same rock.

Is this the only example where radioisotope dating has failed to give correct dates for rocks of known age? Certainly not! Dalrymple2 gives the following potassium-argon ages for historic lava flows (Figure 3):


Historic Lava Flow Potassium-Argon "age" (in millions of years)
Hualalai basalt (Hawaii, AD 1800-1801) 1.6 ± 0.16
Mt. Etna basalt (Sicily, AD 1792) 1.41 ± 0.08
Mt. Lassen plagioclase (California, AD 1915) 0.11 ± 0.3
Sunset Crater basalt (Arizona, AD 1064-1065) 0.27 ± 0.09
0.25 ± 0.15


Now lets look at the truth;

Quote:
Austin sent his samples to a laboratory that clearly states that their equipment cannot accurately measure samples less than two million years old. All of the measured ages but one fall well under the stated limit of accuracy, so the method applied to them is obviously inapplicable. Since Austin misused the measurement technique, he should expect inaccurate results, but the fault is his, not the technique's. Experimental error is a possible explanation for the older date.


Austin's samples were not homogeneous, as he himself admitted. Any xenocrysts in the samples would make the samples appear older (because the xenocrysts themselves would be old). A K-Ar analysis of impure fractions of the sample, as Austin's were, is meaningless.

K/Ar has an effective "minimal geochron limit" of about 100K years because Ar is easily degassed by volcanism. All geologists know this and we all know about "resetting the clock" as a measure of evaluating multiple volcanic events that overlie each other. Also the "xenocrysts' (which are large crystals in the lava body but are foreign to it) can trap the Argon from a previous resetting event and give high incorrect Ar data. Sampling by "blind gotchas" is a common occurence at isotope labs, they have established International Standards for how samples are collected , bagged, sent, and handled . Its almost like A CSI protocol. SoAustin was being his old "fraudulent self" by even using the technique. He knows better, hes been trained in geochronology and he always gets his butt scoured from trying to pull crap like this. He counts on guys like RL to believe his methods as real science, when theyre nothing of the sort. hes a typical fraudulent purveyor of Creationist Swill except he has a Phd in Isotope chemistry and hes using it to fool the Beleievers.

In most cases, we bracket the age of some feature by normal geology and then stratigraphy, then, if radioisotope dating is used, a proper technique, that will work within an error bar , is used. Thats why we dont use C14 on dinosaur bones, or K/Ar on young magmas or devitrified glasses .

Anyway, calling Austin a "geologist" is the zenith of hubris. He got his PhD and a Christian revelation at about the same time (A girl was involved). He then decided to use his education to shoot himself in the foot . He started with Polonium "halos" or birefringence features in micas that are found within granites . His point was to show, by such a short half-lived isotope, by leaving a "ring halo " in the b-axis of mica, this "proved that the granite was young" . He was severely criticized for failing to note that the existence of the Polonium rings was as a result of being Etched into the mica by rad iation, it wasnt an isotopic chemical feature containing polonium itself . It was actually a" fossil imprint" of radioactivity

xingu,

That's kinda the point, isn't it?

If the earth is 'young', then many of the methods currently in use will give false dates indicating an 'old earth', will they not?

Farmerman,

Austin's sample was indisputably recent, whatever one may think of him personally or professionally.
