Potassium argon dating archaeology today, got a youtube account?

In the Creationary Flood Model, essentially all layers were deposited under water. This is because there is no time for any new Argon to form, the only Argon present in the rock would be that which failed to get out of the rock when it was molten. Many text books say it is self-evident.

Decay series Potassium K exists in 3 isotopes - 39K So since the time of the flood, there is no evidence that there has been any change in half-lives of radioactive materials.

Who can edit:

Below the surface of the earth, where would the Argon go? If an experiment is conducted and the information needed to answer the problem is not forthcoming, then another experiment can be designed to answer the problem. Method Because argon is a gas, it is able to escape from molten rock.

This can lead to an inaccurate date. Research in Hawaii shows that the lava flows on the surface of the ground are able to loose essentially all of the Argon. Not Synced [Ah, the Olduvai is gorgeous this time of year!

When volcanic material flows over the land, the naturally occurring Argon gas is driven off by the excess heat. We do actually now have a Facebook page. So potassium-argon dating, it's actually very similar to carbon dating inasmuch as harry dating louis takes advantage of the change from an unstable element to a more stable element.

There is another group that has been conducting experiments for the express purpose of speeding up the transmutation process thus changing the half-life characteristics of radioactive materials. They think that the radioactivity could have speeded up during the flood producing dates with long ages.

References Scientific Theology by Paul A. The Age of the Earth. The point I was making in citing the two articles using Argon gas pressure in both mica and muscovite was to suggest that when the rock heated up, the Argon gas will follow its concentration gradient.

Also, if there is a partial pressure of Argon surrounding the rock, then, as experiments indicate, Argon might even enter the rock during its cooling to increase its content of Argon.

One out of every 10, Potassium atoms is radioactive Potassium K If one of these protons is hit by a beta particle, it can be converted into a neutron.

(K/Ar) Potassium Argon Dating Techniques I

The modern ratio of 40Ar to 36Ar is These older dating rocks give the kind of dates as expected by the scientific community. When the rock is molten hot, it is more liquid in texture, allowing the Argon gas to escape.

So in both cases the Argon flows down the concentration gradient. However, I look at that same data and I come to very different conclusions.

Departures from this assumption are quite common, particularly in areas of complex geological history, but such departures can provide useful information that is of value in elucidating thermal histories. All the other Ar 40 was forced out of the rock by the heat.

As Paul Giem notes: Stanford University Press, p. This is not right! Some samples will not be fully reset, initially. However, when they turn around and say that the data supports the evolutionary viewpoint and not the Creationary viewpoint. They think of the long age scenario of evolution as being fact.

There is no question about it. If the rock is in the lab in a vacuum, the Argon gas will flow out of the rock.

If all the gas is driven off, then there should be no Argon left in the rock. However, this is an assumption that could be challenged. A deficiency of 40 Ar in a sample of a known age can indicate a full or partial melt in the thermal history of the area. A paradigm is a theory that is so well accepted that no one seriously questions it.

The areas of science, which are the most successful, which the public notices, are the amazing discoveries in medicine, biology, space exploration, and the like. Well you can escape.

Limitations of the Historical Sciences In any kind of a historical science, assumptions have to be made in the assessing of historical dates.

Plutonic rocks are rocks are rocks that have solidified below the ground.

This is the key principle behind K-Ar dating. For this reason, only trained geologists should collect the samples in the field. But if the Argon pressure is greater outside the rock, then the Argon will flow into the rock.

This is very interesting. It has as its basis of understanding, various assumptions which concern the conditions of the Earth for hundreds of millions of years. Your Questions Answered I'm sure you've had many responses to your article about the potassium-argon dating article and I'm sure sure you won't respond to this one.

Internet URLs are the best. This approach permits the analyses of single grains, and the use of a more refined step-heating approach that greatly improves the reliability of the result and eliminates the need to do an independent analysis for the potassium.

Foreign material, composed of small rocks and crystals xenoliths and xenocrysts were mixed into the lava. The data does not support long ages. The technique works well for almost any igneous or volcanic rock, provided that the rock gives no evidence of having gone through a heating-recrystallization process after its initial formation.

It is based on the fact that some of the radioactive isotope of Potassium, Potassium K ,decays to the gas Argon as Argon Ar The ratio of K to total K is constant. In the K—Ar method was used by the Mars Curiosity rover to date a rock on the Martian surface, the first time a rock has been dated from its mineral ingredients while situated on another planet.

The fifth assumption is fairly safe. But this kind of work has not been published. This approach permits the 39K and the 40K to be directly determined along with the 40Ar and eliminating the need to separately analyze for potassium.

On Pagewe can also note: K—Ar dating was instrumental in the development of the geomagnetic polarity time scale.
