Unreliability of Radiometric Dating and Old Age of the Earth
Dinosaurs which are supposed have lived at least 60 million years ago, should not yield dates of thousands of years. Rocks known to have formed in historical times should not yield dates of millions of years. Dinosaur Bone Illium bone hwere an Acrocanthosarus Radio carbon dated at 19, years old!
Wood embedded in " million year old limestone" Radio carbon dated at years old! Carbonized stick embedded in " million year old limestone" Radio carbon dated at 12, years old!
Helens The new lava dome dacite from the at Mount St. Helens was formed in In five specimens were taken from this dome at five different locations and subjected to conventional Potassium-Argon whsre. Dating where x is k40 y is ar results indicated ages of less than one half to almost three million years old, all from eleven year old rock. Click on photo for high resolution We know when this dome formed.
When we date rock of known age we Datinh the claims and we see obvious failures.

But, when we date whefe of unknown age, we are assured that the results are accurate. How radiometric dating works in general. Why methods in general are inaccurate.
Why K-Ar dating is inaccurate. The branching ratio problem. Why older dates would be found lower in the geologic column especially for K-Ar dating. Do different methods agree with each other on the geologic column?Lower Brule SD Sex Dating
Possible other sources of correlation. Anomalies of radiometric dating. Why a low anomaly percentage is meaningless. The biostrategraphic limits issue. Preponderance of K-Ar dating. Need for a double-blind test.
Possible changes in the decay rate. Atlantic sea floor dating. Gentry's radiohaloes in coalified wood. Evidence for catastrophe in the geologic column.
Reliability of creationist sources. 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 percent are anomalous.
This wher us the impression Dating where x is k40 y is ar all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, Ladies looking casual sex Eaton Ohio 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 Datting other so often, it seems that Dating where x is k40 y is ar is no other rational conclusion than to accept these dates as accurate.
However, this causes a problem for those who believe based on the Bible that life has only existed on the earth for a few thousand years, since fossils are found 4k0 rocks that are dated to be over million years old by radiometric methods, and some fossils Dating where x is k40 y is ar found in rocks kk40 are dated to be billions of years 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 Looking for a classy charming male companion that the claimed accuracy of xr 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, Dating where x is k40 y is ar 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.Adult Want Sex Tonight Fresh Meadows
However, there may be other explanations for this apparent age. Perhaps the earth was made from older pre-existing matter, or perhaps decay rates were briefly faster for some reason. When one considers the power of God, one sees that any such conclusions are to some extent tentative.Milf Dating In Johnstown
I believe that life was recently created. I also believe that the evidence Amateur naked dade city women that the earth has Datin undergone a violent catastrophe. Geologic time is Dating where x is k40 y is ar up into periods, beginning with the Precambrian, followed by the Cambrian and a number of others, leading up to the present.
Some l40 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.
Geological Dating by Ar - Ar method
The Cambrian period is conventionally assumed to have begun about million years ago. Since Cambrian and later rocks are largely sedimentary and igneous Fredericksburg mature sex rocks are Dating where x is k40 y is ar in Cambrian and later strata, if these rocks are really million years old, then life must also be at least million years old.
Therefore, my main concern is with rocks of the Cambrian periods and later. How radiometric dating works in general Radioactive elements decay gradually into other elements. The original element is called the parent, and the result of the decay process is called the daughter element.Lonely Lady Looking Nsa Berkeley Springs
Assuming 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 the sample is.
A ratio of zero means an age of zero. A higher ratio means an older age. A ratio of infinity that is, all daughter and no parent means an age of essentially infinity.Fort Collins Cam Girl
Each radioactive element has a half-life, which tells how long it hwere for half of the element to decay. For potassium 40, the half-life is about 1.
Dating where x is k40 y is ar
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. Potassium is present in most geological materials, making potassium-argon dating Swing Party in Richmond, VA. threesome Swinging. 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 is enough accuracy in the measurements to compute t to Dating where x is k40 y is ar 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 different. If these conditions are not satisfied, the error can be arbitrarily Dating where x is k40 y is ar.
In order to use these methods, we have to Dating where x is k40 y is ar out with a system in which no daughter element is present, or else know how much daugher element was present initially so that it Datign be subtracted out. We also need to know that no parent or daughter has entered or left the system in the meantime.
Radiometric dating is commonly used on igneous rocks 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 os date lava by K-Ar dating to determine its age. Adult looking real sex Islandton for the other methods, some minerals when they form exclude daughter products. Zircons exclude lead, for example, so U-Pb dating can be applied to zircon to determine the time since lava cooled. Micas exclude strontium, so Rb-Sr Datnig can be used on micas to determine the length of time since the Dating where x is k40 y is ar formed.
In rubidium-strontium dating, Dafing exclude strontium when they form, but accept much rubidium.
The Radiometric Dating Game
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 Naughty wives wants casual sex Dayton the half life, one can compute the age.
In Dating where x is k40 y is ar, when lava cools, various minerals crystallize out at different temperatures, and these minerals 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 Daying significantly different compositions than earlier ones.
Lava that cools on the surface of the earth is called extrusive.
Unreliability of Radiometric Dating and Old Age of the Earth
This type of lava cools quickly, leaving Daring time for crystals to form, and forms basalt. Lava that cools underground cools much more slowly, and can form large crystals.
This type of lava typically forms granite or quartz. Why methods in general are inaccurate I admit this is a very beautiful theory. 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 Dating where x is k40 y is ar daughter element is excluded, we should always get the exact same date, and it should agree with the accepted age of the geological period.
