Radiocarbone dating games

opinion

Some updates to this article are now available. The sections on the branching ratio and dating meteorites need updating. Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.

We are told that these methods are accurate to a few percent, and that there are many different methods. We are told that of all the radiometric dates that are measured, only a few "Radiocarbone dating games" are anomalous.

This gives us the impression that Radiocarbone dating games but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points.

Since there doesn't seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as Radiocarbone dating games. However, this causes a problem for those who believe Radiocarbone dating games on the Bible that life has only existed on the earth for a "Radiocarbone dating games" thousand years, since fossils are found in rocks that are dated to be over million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of Radiocarbone dating games old.

If these dates are correct, this calls the Biblical account of a recent creation of life into question. After study and discussion of this question, I now believe that the claimed accuracy of radiometric dating methods is a result of a great misunderstanding of the data, and that the various methods hardly ever agree with each other, and often do not agree with the assumed ages of the rocks in which they are found.

I believe that there is a great need for this information to be made known, so I am making this article available in the hopes that it will enlighten others who are considering these questions.

Even the creationist accounts that I have read do not adequately treat these issues. At the start, let me clarify that my main concern is not the age of the earth, the moon, or the solar system, but rather the age of life, that is, how long has life existed on earth. Many dating methods seem to give about the same ages on meteorites. Thus radiometric dating methods appear to give evidence that the earth and meteorites are old, if one accepts the fact that decay rates have been constant.

However, there may be other explanations for this Radiocarbone dating games age. Perhaps the earth was made from older pre-existing Radiocarbone dating games, or perhaps decay rates were briefly faster for some reason. When one considers the power of God, one sees that "Radiocarbone dating games" such conclusions are to some extent tentative.

For some evidence for a young universe, see http: For some evidence for a young sun, see http: I believe that life was recently created. I also believe that the evidence indicates that the earth has recently undergone a violent catastrophe. Geologic time is divided up into periods, beginning Radiocarbone dating games the Precambrian, followed Radiocarbone dating games the Cambrian and a number of others, leading up to the present.

Some fossils are found in Precambrian rocks, but most of them are found in Cambrian and later periods. We can assume that the Precambrian rocks already existed when life began, and so the ages of the Precambrian rocks are not necessarily related to the question of how long life has existed on earth. The Cambrian period is conventionally assumed to have begun about million years ago. Since Cambrian and later rocks are largely sedimentary and igneous volcanic rocks are found in Cambrian and later strata, if these rocks are really million Radiocarbone dating games old, then life must also be at least million years old.

Therefore, my main concern is with rocks of the Radiocarbone dating games periods Radiocarbone dating games later.

Half Life; Decay Rates; Measurement;...

How radiometric dating works in general Back to top Radioactive elements decay gradually into other elements. The original element is called the parent, Radiocarbone dating games the result of the decay process is called the daughter element.

Radiocarbone dating games we start out with pure parent, as time passes, more and more daughter will be produced. By measuring the ratio of daughter to parent, we can measure how old Radiocarbone dating games sample is. A ratio of zero means an age of zero. "Radiocarbone dating games" higher ratio means an older age. A ratio of infinity that is, all daughter and no parent means an age of essentially infinity.

Each radioactive element has a half-life, which tells how long it takes for half of the element to decay. For potassium 40, the half-life is about 1. In general, in one half-life, half of the parent will have decayed. Potassium 40 K40 decays to argon 40, which is an inert gas, and to calcium.

Understand how decay and half...

Potassium is present in most geological materials, making potassium-argon dating highly useful if it really works. Uranium decays to lead by a complex series of steps. Rubidium decays to strontium.

When it is stated that these methods are accurate to one or two percent, it does not mean that the computed age is within one or two percent of the correct age.

It just means that there Radiocarbone dating games enough accuracy in the measurements to compute t to one or two percentage points of accuracy, where t is the time required to obtain the observed ratio of daughter to parent, assuming no initial daughter product was present at the beginning, and no daughter or parent entered or left the system. For isochrons, which we will discuss later, the conditions are Radiocarbone dating games. If these conditions are not satisfied, the error can be arbitrarily large.

In order to use these methods, we have to start out with a system in which no daughter element is present, or else know how much daugher element was present initially so that it can be subtracted out. We also need to know that no parent or daughter has entered or left the system Radiocarbone dating games the meantime.

Radiometric dating is commonly used on igneous Radiocarbone dating games lavaand on some sedimentary minerals. But fossils can generally not be dated directly. When lava is hot, argon escapes, so it is generally assumed that no argon is present when lava cools. Thus we can date lava by K-Ar dating to determine its "Radiocarbone dating games." As for the other methods, some minerals when they form exclude daughter products.

Zircons exclude lead, Radiocarbone dating games example, so U-Pb dating can be applied to zircon to determine the time since lava cooled. Micas exclude strontium, so Rb-Sr dating can be used on micas to determine the Radiocarbone dating games of time since the mica formed.

I found the following statement in an on-line non creationist reference, as follows: In rubidium-strontium dating, micas exclude strontium when they form, but accept much rubidium. In uranium-lead U-Pb dating of zircon, the zircon is found to exclude initial lead almost completely. The Interpretation and Dating of the Geologic Record. Thus one would know that any strontium that is present had to come from the parent rubidium, so by computing the ratio and knowing the half life, one can compute the age.

In general, when lava cools, various minerals crystallize out at different temperatures, and these Radiocarbone dating games preferentially include and exclude various elements in their crystal structures.

So one obtains a series of minerals crystallizing out of the lava. Thus the composition of the lava continues to change, and later minerals can form having "Radiocarbone dating games" different compositions than earlier ones.

Lava that cools on the surface of the earth is called extrusive. This Radiocarbone dating games of lava cools quickly, leaving little time for crystals to form, and forms basalt. Lava that Radiocarbone dating games underground cools much more slowly, and can form large crystals. This type of lava typically forms granite or quartz.

A good general introduction Radiocarbone dating games radiometric dating from an evolutionary perspective can be found at http: Why methods in general are inaccurate Back to top I admit this is a very beautiful theory.

Expertise. Insights. Illumination.

This would seem to imply that the problem of radiometric dating has been solved, and that there are no anomalies. So if we take a lava flow and date several minerals for which one knows Radiocarbone dating games daughter element is excluded, we should always get the exact same date, and it should agree with the accepted age of the geological period. I doubt it very much.

If the radiometric dating problem has been solved in this manner, then why do we need isochrons, which are claimed to be more accurate? The same question could be asked in general of minerals that are thought to yield good Radiocarbone dating games. Mica is thought to exclude Sr, so it should yield good Rb-Sr dates. But are dates from mica always accepted, and do they always Radiocarbone dating games with the age of their geologic period?

Indeed, there are a number of conditions on the reliability of radiometric dating. For example, for K-Ar dating, we have the following requirements: For this system to work as a clock, the following 4 criteria must be fulfilled: The decay constant and the abundance of K40 Radiocarbone dating games be known accurately.

There must Radiocarbone dating games been no incorporation of Ar40 into the mineral at the time of crystallization or a leak of Ar40 from the mineral following crystallization. The system must have remained closed for both K40 and Ar40 since the time of crystallization. The relationship between the data obtained and a specific event must be known. The requirements for radiometric dating are stated in another way, at the web site http: The earth is supposed to be nearly 5 billion years old, and some of these methods seem to verify ancient dates for many of earth's igneous rocks.

The answer is that these methods, are far from infallible and are based on three arbitrary assumptions a constant rate of decay, an isolated system Radiocarbone dating games which no parent or daughter element can be added or lost, and a known amount of the daughter element present initially. Heating and deformation of rocks can cause these atoms to migrate, and water percolating through the rocks can transport these substances and redeposit them.

These processes correspond Radiocarbone dating games changing the setting of the clock hands. Not infrequently such resetting of the Radiocarbone dating games clocks is assumed in order to explain disagreements between different measurements of rock ages.

Some more quotes from the same source: In the lead-uranium systems both uranium and lead can migrate easily in some rocks, and lead volatilizes and escapes as a vapor at relatively low temperatures. It has been suggested that free neutrons could transform Pb first to Pb and then to Pb, thus tending Radiocarbone dating games reset the clocks and throw thorium-lead and uranium-lead clocks completely off, even to the point of wiping out geological time.

Furthermore, there is still disagreement of 15 percent between the two preferred values for the U decay constant. Potassium volatilizes easily, is easily leached by water, and can migrate through the rocks under certain conditions. Furthermore, the value of the decay constant is still disputed, although the scientific community seems to be approaching agreement.

Historically, the decay constants used for the various radiometric Radiocarbone dating games systems have been adjusted to obtain agreement between the results obtained. Argon, the daughter substance, makes up about "Radiocarbone dating games" percent of the atmosphere, which is therefore a possible source of contamination.

However, since it is possible for argon to be formed in the rocks by cosmic radiation, the correction may also be in error. Half Life; Decay Rates; Measurement; Dating Game. Choose Nucleus. Carbon- Nitrogen Uranium Lead Custom.

They believe from time to time artifact dug up or discovered close to archeologists, anthropologists, geologists, or other scientists can bear its time eon accurately intent, within a narrow series, by carbon dating.

But is that the truth? First, it is based on the ratio of two elements—carbon 12 C to carbon 14 C —found in a trial of the object being dated. All living details, directly or indirectly, absorb carbon from the heavens. The carbon absorbed is both C and C and it is wrapped up at the same relationship as it exists in the environment.

The Radiometric Dating Game

Since even rocks with old K-Ar dates still absorb more argon from the atmosphere in short time periods, it follows that rocks should absorb quite a bit of argon over long time periods, especially at higher pressures. In a similar way, argon could enter the rock from the air or from surrounding rocks and make it look older. Here are some quotes from http: It is composed of little glass beads that come from volcanic ash.

By the way, Ar-Ar dating and K-Ar dating are essentially the same method, so between the two of them we obtain a large fraction of the dates being used.
