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. Carbon-14, radiometric dating and index fossils carbon dating is used to determine the age of biological artifacts up to 50,000 years old this technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old. Other radiometric dating methods such as potassium-argon or rubidium-strontium are used for such purposes by those who believe that the earth is billions of years old radiocarbon is not suitable for this purpose because it is only applicable: a) on a time scale of thousands of years and b) to remains of once-living organisms (with minor exceptions, from which rocks are excluded. To date rocks or other objects, scientists typically use radiometric dating in short, the ratio of radioactive and stable isotopes in the sample are determined and the measured rate at which the isotopes decay is used as an indicator of the age of the sample.
Best answer: radiometric dating cause uncertainties or is it a reliable, sure-fire means of dating rock the absolute ages aren't strictly absolute, and allowance is made for uncertainty. This illustrates the whole problem with the radioactive dating of geological events those who promote the reliability of the method spend a lot of time impressing you with the details of radioactive decay, half-lives, mass-spectroscopes, etc. We previously reported an event organized by the adelaide, australia, chapter of reasonable faith where dr justin payne, a lecturer within the school of earth and environmental sciences at the university of adelaide, sought to ‘disprove’ objections to long-age radiometric dating.
There is, of course, one radiometric dating method that appears to overcome the vital zero date problem so, it is starting to look like isochron dating has solved some of the major problems of other dating methods however, isochron dating is still based on certain assumptions. Radiometric dating is a method of determining the age of an artifact by assuming that on average decay rates have been constant (see below for the flaws in that assumption) and measuring the amount of radioactive decay that has occurred. Response: [wiens' article] has listed and discussed a number of different radiometric dating methods and has also briefly described a number of non-radiometric dating methods there are actually many more methods out there well over forty different radiometric dating methods are in use, and a number of non-radiogenic methods not even mentioned here. Several types of radiometric dating methods are used today one of the best known is carbon 14 (c-14) when a plant or animal dies, the carbon in it has a small amount of radioactivity.
Radiometric dating utilizes the decay rates of certain radioactive atoms to date rocks or artifacts uniformitarian geologists consider this form of dating strong evidence that the earth is billions of years old but new research by creationists has revealed a large number of problems with radiometric dating. Third, many dating methods that don't involve radioisotopes—such as helium diffusion, erosion, magnetic field decay, and original tissue fossils—conflict with radioisotope ages by showing much younger apparent ages these observations give us confidence that radiometric dating is not trustworthy. Two kinds of magma and implications for radiometric dating it turns out that magma has two sources, ocean plates and material from the continents (crustal rock) this fact has profound implications for radiometric dating.
The biggest problem with dating methods is the assumption that the rate of decay has remained constant there is no way to prove it in fact there is much evidence to show this rate has not remained constant, and that it is decaying quicker and quicker. Radiometric dating or radioactive dating is a technique used to date materials such as rocks orexample of a radioactive decay chain from lead-212 212pb to lead-208 208pbrubidium-strontium dating is not as precise as the uranium-lead method, with errors of 30 to 50 million years for a 3-billion-year-old 3 examples of radioactive dating sample. Radiometric dating of rocks and minerals using naturally occurring us who have developed and used problems with radiometric dating dating techniques to solve scientific problems are wellit was a little embarrassing because the patient and his wife were both doctors probably working in research both were happy with their treatment and theduring this time he said that his boys were resting and gaining strength after their terrible ordeals in the untracked jungle to the south but he had not.
Radiometric dating prior to 1905 the best and most accepted age of the earth was that proposed by lord kelvin based on the amount of time necessary for the earth to cool to its present temperature from a completely liquid state. The guide describes a number of radiometric methods and states that for ‘suitable specimens the errors involved in radiometric dating usually amount to several percent of the age result thus a result of two hundred million years is expected to be quite close (within, say, 4 million) to the true age. Radiometric dating half-life problems radiometric dating half-life the following material has been taken from a sheet entitled several faulty assumptions are used in all radiometric dating methodscarbon 14 is used for this example , which was put out by drhovind r1 the atmospheric c-14 is presently only 1 3 of the way to an equilibrium.
Radiometric dating - a brief explanation radiometric dating is the primary dating scheme employed by scientists to determine the age of the earth radiometric dating techniques take advantage of the natural decay of radioisotopes. There are well over forty different radiometric dating methods, and scores of other methods such as tree rings and ice cores all of the different dating methods agree--they agree a great majority of the time over millions of years of time. Various problems with the three main types of radiometric dating lastly, an examination and discussion will be presented of how these methods can give unreliable dates.
