    only rarely does a creationist actually find an incorrect radiometric result (austin 1996; rugg and austin 1998) that has not already been revealed and discussed in the scientific literature. numerous thin beds of volcanic ash occur within these coals just centimeters above the k-t boundary, and some of these ash beds contain minerals that can be dated radiometrically. to demonstrate that excess argon is a 'problem' for k-ar dating by. dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life.  however, research by geologist john woodmorappe (a pen name) revealed that the radiometric methods used today were actually hand-picked to coincide with the dates previously assumed for the geologic column diagrams. austin does indeed identify a real potential weakness in potassium-argon dating. scientists from the us geological survey were the first to obtain radiometric ages for the tektites and laboratories in berkeley, stanford, canada, and france soon followed suit.

Carbon Dating Undercuts Evolution

for example, after extensive testing over many years, it was concluded that uranium-helium dating is highly unreliable because the small helium atom diffuses easily out of minerals over geologic time. because of their importance, meteorites have been extensively dated radiometrically; the vast majority appear to be 4. it is these studies, and the many more like them documented in the scientific literature, that the creationists need to address before they can discredit radiometric dating. measuring the age of this impact event independently of the stratigraphic evidence is an obvious test for radiometric methods, and a number of scientists in laboratories around the world set to work., if results are found that differ from hypothesized, such as the level of helium in the zircon, isn’t the best scientific method to search for an explanation, rather than give up and assume that the u/pb dating is completely false and therefore creation is correct? the radio-dating calculations are based on a series of assumptions:1) the decay rate has not changed. third, the radiometric ages agree, within analytical error, with the relative positions of the dated ash beds as determined by the geologic mapping and the fossil assemblages; that is, the ages get older from top to bottom as they should.

austin submitted the sample for radiometric dating to an independent laboratory in cambridge, massachusetts. results of the manson impact/pierre shale dating study (izett and others 1998) are shown in figure 1. this is extremely powerful verification of the validity of both the theory and practice of radiometric dating. it is only good for a dating back with any confidence to less than 80,000 years. if radiometric dating didn’t work then such beautifully consistent results would not be possible. for more than five years, the rate team labored examining modern dating techniques and found that these techniques do not support an earth that is billions of years old. how could all of this be so if the 40ar/39ar dating technique did not work?

and other c14 tests are also referenced in this site:In “evolution and carbon-14 dating “ by eric lyons, m. these samples were sent to independent labs for c-14 dating. from many decades of such experience, geologists have excellent data that guides proper usage of each of these tools, and they don't include gross misuse of potassium-argon dating. the 122 bce flow from mt etna, for example, gave an erroneous age of 0. some so-called creation scientists have attempted to show that radiometric dating does not work on theoretical grounds (for example, arndts and overn 1981; gill 1996) but such attempts invariably have fatal flaws (see dalrymple 1984; york and dalrymple 2000). scientists have concluded that it is not; it is instead a consequence of the fact that radiometric dating actually works and works quite well. perhaps you could give more information on this c14 dating of fossils?

and there's pretty good reason for this: geology dating is pretty complicated, and if you look at dr. have acknowledged that the c-14 dating methods are unreliable for material which is more than 80,000 years old, as you have said, so why would the results of such dating be significant?. deyoung authored this non-technical book in order to equip the layperson to defend scientific six-day creation and refute modern dating techniques.  it is the prime reason many scientists have had doubts about radiometric dating all along. certainly there is no doubt that the test was far outside the useful parameters of potassium-argon dating, but whereas critics say this invalidates the results, austin concludes that his results certify that the test is universally useless. radioisotope dating, using the trace amounts of radioactive elements within the rock, was quickly accepted as proof the earth is millions and millions of years old. is rare for a study involving radiometric dating to contain a single determination of age.

second, the radiometric age measurements, 187 of them, were made on 3 different minerals and on glass by 3 distinctly different dating methods (k-ar and 40ar/39ar are technical variations that use the same parent-daughter decay scheme), each involving different elements with different half-lives. is not the only dating study to be done on an historic lava flow., yecs clearly believe that they can discredit k-ar dating if they. not only that, they have to show the flaws in those dating studies that provide independent corroborative evidence that radiometric methods work. is an article by an independent research group that explains c14 dating and its issues, as well as their procedures for testing dinosaur bone samples – not just for c14 but also for collagen. few verified examples of incorrect radiometric ages are simply insufficient to prove that radiometric dating is invalid.“… you mentioned that there are samples of dinosaur bones which returned c14 dating in ‘thousands’ rather than millions of years old… is there any other information on this?

John D. Morris - Wikipedia

see, the radiometric dating technique’s do not work when you can check the dates, but you should trust them when you can’t check them. in order to accomplish their goal of discrediting radiometric dating, however, creationists are faced with the daunting task of showing that a preponderance of radiometric ages are wrong — that the methods are untrustworthy most of the time. purpose of this paper is to describe briefly a few typical radiometric dating studies, out of hundreds of possible examples documented in the scientific literature, in which the ages are validated by other available information. this short paper i have briefly described 4 examples of radiometric dating studies where there is both internal and independent evidence that the results have yielded valid ages for significant geologic events. and the ages assigned to the layers were derived from long age evolutionary assumptions – not from the scientific facts, – as the column was established long before we even had radiometric dating. he was deliberately trying to illustrate that even a brand-new rock would show an ancient age, even when potassium-argon dating was properly used. with ar-ar dating, where excess argon can often be distinguished.
