Radiometric Dating

pros and cons of radioactive dating

May 1, The End. A method of radioactive dating is called carbon dating Cons: 1. Expensive, because you have to determine the isotope of very trace. Pros and cons of carbon dating radiocarbon dating is an absolute Con all radioactive dating except carbon 14 are based on atoms found in igneous rocks. pros and cons of radiometric dating. Pro radioactive dating gives an absolute age for the rocks radioactive dating can be used to date fossils older.

However, the answer to the detection of C in diamonds fits a young earth hypothesis just as good, if not better, than Th creating C which is lacking in evidence. Furthermore, U and Th decay does create Helium. He is the second lightest element and diffuses out of minerals and rocks quickly. They have measured He diffusion rates from Zircons that are supposedly 1. It seems not all dating methods cross-check each other as my opponent asserts.

So why do some independent dating methods appear to match? The simple answer is they don't. The conventional geological community has the presupposition that the earth is billions of years old.

So when they date a rock layer with any radiometric dating method that doesn't match the "expected" age they already had for the rock layer they throw it out and keep dating until they get the results they wanted. It has been admitted as such: If it does not entirely contradict them, we put it in a footnote, and if it is completely out of date we just drop it" T. True, this quote is frombut why should we believe scientists are any different today?

The only way scientists know radiometric dating results are incorrect is because they already had preconceived ideas of the what the age of a rock was. It is the relentless application of uniformitarianism that creates these perceived matches with independent dating methods. It is assumed that tree rings form one a year, but it is actually well known that tree rings can form several in one year depending on the climate the tree is growing in http: If we eliminate the uniformitarian philosophy we can see that it makes the assumption of tree rings difficult to prove.

Furthermore, the oldest tree, appropriately nicknamed Methuselah, is only years old according to conventional dating http: If the earth is billions of years old why are there not any older trees than a few thousand years old?

Varves are conventionally believed to be laid down one a year. However, a Florida Hurricane deposited a six-inch-thick mud layer with numerous thin laminae Journal of Geology, What would a yearlong global flood do? Coral reef growth is claimed to take long ages to have grown. The Enewetok Atoll in the Pacific Ocean is usually pointed to as an example.

An Annual Review, Based on these measurements the Enewetok Atoll would have only taken years to grow. Instead, we impose long ages on coral reefs. Most Speleotherms in modern caves are not growing. However, observations of those still growing have reported growth of stalactites at 7. If these measurements are applied to the Great Dome stalagmite in Carlsbad Cavern, it would have grown in less than years.

Furthermore, radiocarbon ages of speleothems are deceptive, because the carbon incorporated in the speleothem minerals is out of equilibrium with the atmospheric carbon. Absolute dating has proved disappointing http: Antarctic ice cores are dated by this method, since the accumulation on this ice sheet is so low that annual layer dating cannot be applied, except in shallow coastal cores with higher snowfall.

So, theyears obtained near the bottom of the Vostok ice core is based on preconceived ideas on the ages of ocean sediment, which is based on the astronomical theory of the Ice Age.

Radiometric Dating is Accurate

In other words, the uniformitarian scientists date the ice sheets to hundreds of thousands of years because they believe the ice sheets are old to begin with. They have "proved" only what they have assumed! Fission tracks and electron spin resonance is dependent on the rate of decay of isotopes. So of course they match the radiometric dating. If decay had been accelerated in the past so would have fission tracks and electron spin resonance.

If someone believes it is 3: Pro This is has been a good debate. I've gotten to revisit many aspects of the science. If radiometric dating were inaccurate, it would be easy to show it. Anyone could have samples dated by various different techniques using different laboratories. Labs performing radiometric dating are on the Internet, and they will provide services to anyone.

A double-blind technique could be used to prevent any bias in evaluation. If the dates are inconsistent, then the dating is inaccurate. Scientists have done this many times, and the dates are very consistent. Critics claim the scientists are just pretending there is consistency.

If so, critics could run the experiments themselves and show the results they obtained. Critics don't do that. Critics do not even try the simple tests. The method critics employ is like searching for broken wrist watches, and upon finding a dozen, then claiming that wrist watches are utterly useless for telling time. If the methods were not accurate, it would be easy for critics to present contradictory statistical data, but there is none.

It is impossible for a flood to produce varve sediments with layers having pollen grains sorted by season in the layers. Sediments in floods may appear in layers, but the layers depend upon materials settling out of the water at different rates. Mixing a solution and having it settle in repeating patterns of spring-summer-fall-winter pollen, each in discrete layers, is an impossibility.

No physical mechanism for that has been suggested and none demonstrated. Pollen types and fish scale types in varve columns are used to study past climates. The species of plant or fish present indicates the climate at the time the sediment was deposited. Periods of climate warming and cooling are thus tracked. A great flood would produce a sample of only one climate condition, when the flood occurred. Spectral analysis of sediment layers is also used to count solar cycles, lunar cycles, sunspot cycles, and Milankovitch bands, independently confirming the age of the layers.

Varve columns produce the same number of layers, corresponding to the years, at dozens of independent sequences around the world. There is no reason to suppose the number of layers would match globally, as in fact observed. Also, if all the water on earth were added to the oceans it would only make them rise by feet. Many sediments columns have been measured in lake areas more than ft above sea level.

Con wrongly claims that the individual layers of ice cores are not counted. The layers are in fact individually counted. The religious-inspired counterargument is that maybe the layers are formed by individual snow storms so that there are fewer years than layers. In that way, they hope to get a record of hundred of thousands of years reduced to just a few thousand, as they require.

These didn't melt it get Flood waters? The way that scientists distinguish years is to measure isotopes that vary with the seasons. Water having one isotope of oxygen evaporates faster than water having another isotope, so the ratio is a proxy for seasonal temperature. Also isotopes of beryllium and chlorine vary with sunspot cycle, but that is a secondary confirmation. The reason we know that the Institute for Creation Research and their allied journals are religious is that their motto is "Biblical - Accurate - Certain" as shown in the header of the Snelling paper http: No scientific journal can claim papers are required to conform with the Bible or that results are certain.

In counting tree rings, very rarely, two growth rings can occur in one season. When this happens it is obvious, so accurate counting is not a problem. The reason is that trees die, of course, and ultimately the remains decay.

What are the advantages and disadvantages of relative and radiometric dating

However, the pattern of yearly growth can be correlated between trees in overlapping generations, like matching bar codes. Using that method, tree rings can be used for dating back about 7, years in North America http: The allegations that there are widespread problems is simply false, and nothing other than a few particular problems is offered. Recent lava flows producing ancient dates is traced to the recent flows having incorporated old olivine.

If Snell's critiques were valid general criticisms he would publish them in the peer-reviewed literature rather than unreviewed religious tracts. He could not get away with the generalization in a scientific journal. Con claims "Fission tracks and electron spin resonance is dependent on the rate of decay of isotopes. So if the decay rates changed, they would have to change in exactly the same way in each. But there is no known mechanism by which any of them can be changed, and there is no theory that supports even one changing.

There is ample experimental verification that decay rates are not affected by environmental factors. Fission tracks are formed after a mineral crystallizes from the molten state, and it measures times up to about two billion years past. If the time scale were dramatically in error, all the volcanism in two billion years would have to be compressed into a few years. That is not possible under all the rates of heating and cooling have also changed, implying the basic physical laws had changed along with that, but improbably remain consistent with respect to crosschecking.

Con ridicules crosschecking, but it is both logical and valid. He offers no scientific alternative. Con quotes one article from in which a scientist says he throws away data he doesn't like.

Con then claims that all scientists always do the same.

That claim is unsupported. Scientists are renowned for showing errors in previous results, not by confirming them. Showing a serious error would win a Nobel prize. The geological time scale is confirmed by dozens of independent methods employed by many thousands of scientists from around the world.

Con All thanks goes to Pro for a robust debate! Pro has argued that my position, and the evidence I have presented, has been "religious-inspired" and, therefore, is not valid. However, he fails to see that the evidence he has presented has been uniformitarian-inspired, which is just a naturalistic philosophical lens through which all his data has been interpreted. Just because ICR gives glory to God does not make their data any less scientific. Just as a uniformitarian philosophy does not make data any less scientific.

We need to look at the data and see whose interpretive framework fits the data the best. Conventional geologists look at current varve forming sediment layers on the beds of existing lakes and immediately assume this must have been the same mechanism that formed the varves in the geologic column. Therefore, they interpret the rock column as such. There are more than a million varves in some parts of the formation.

The uniformitarian interpretation is there was an ancient lake that existed for a million years. However, this is just an assumption because no one was there to prove it! The problem with this interpretation is that the laminae are entirely too thin and uniform, and extend over too wide an area to have been deposited on the floor of an abnormally calm lake.

Furthermore, part of the formation has layers of volcanic ash tuff bedsand there are layers of varves situated between these two tuff beds. Mass spectrometers are made up of an ion generator, analyzer, and several detectors. The sample is ionized using the ionic generator and then passed through a magnetic field that separates the samples into different groups based on their mass and ionization levels. When each ionized sample reaches the Faraday Cup in which it is stored, a current is produced and measured as an electrical signal.

A computer can then identify the types of atoms present in the sample as well as the number of atoms the sample has. Modern Radiometric Dating Techniques Modern radiometric dating uses many different techniques to identify both organic and inorganic objects. For example, uranium-lead experiments are often conducted on older, inorganic objects because uranium-lead conversions have a much longer half-life than other isotopes.

However, Carbon tests are conducted on relatively young, organic objects because organisms only replenish Carbon while they are alive. By using Carbon tests, scientists can calculate how long it has been since the organism died.
