Jul 30, But the basic concept of radioactive dating, sometimes called radiometric dating, is not difficult, especially since all of us regularly calculate how. Nov 14, Radiometric dating is flawed - Find single woman in the US with More dates, all lyrics radiometric dating is going through the majority of years. Jan 31, By evaluating the concentrations of all of these isotopes in a rock to only be influenced by the radioactive decay of the rubidium into.

At the time of formation for a rock, the isotopes for an element are homogenized and so the composition of a certain isotope is the same in all the minerals in the rock. But what happens when the rocks have been disturbed?

Radiometric Dating Does Work!

If so, the data will not fall on an isochron line, but will be all over the place. This tells scientists that the sample has been disturbed and cannot be dated with this particular method. So far from rejecting samples because they do not fit a preconceived notion of what the age should be, scientists reject samples because there is ample evidence that it has been disturbed: Scientists do not assume that rocks have been closed systems; it is a well-supported conclusion from experiments.

But what about assuming that initial amounts are known? Radiometric dating and initial conditions A second property of isochron diagrams is that it actually gives the initial amount of daughter isotope as a result of the method. It is just the y-intercept of the isochron line. The initial conditions are just read off the graph; it is not just assumed. Radiometric dating and decay rates In a last ditch effort, young earth creationists exclaim that scientists just assume, without warrant, that decay rate are constant.

However, this is not the case. Decay rates have been shown to be constant, despite very high pressure and temperature. Furthermore, by studying supernovas far away, scientist have determined that decay rates have been constant in the ancient past as well. Not only that, different radioactive isotopes decay differently and it is enormously improbable that a postulated difference in decay rates would affect all of them in the same way, yet as we have seen, different radiometric dating methods converge on the same date within margins of error.

Fourthly, decay rates can be predicted from first principles of physics.

Any change would have to correspond to changes in basic physical constants. Any such change would affect different forms of decay differently, yet this has not been observed.

As a final blow to the already nailed shut coffin of young earth creationism, had decay rates been high enough to be consistent with a young earth, the heat alone would have melt the earth. Conclusion Scientists do not assume that rocks have been closed systems, but they test for it.

If all the data points fall on the isochron line, it has been a closed system; it it scatters, it has not and that rock is not used for dating with that method.

In addition to shocked quartz grains and high concentrations of iridium, the K-T impact produced tektites, which are small glass spherules that form from rock that is instantaneously melted by a large impact. The K-T tektites were ejected into the atmosphere and deposited some distance away. Tektites are easily recognizable and form in no other way, so the discovery of a sedimentary bed the Beloc Formation in Haiti that contained tektites and that, from fossil evidence, coincided with the K-T boundary provided an obvious candidate for 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. The results from all of the laboratories were remarkably consistent with the measured ages ranging only from Similar tektites were also found in Mexico, and the Berkeley lab found that they were the same age as the Haiti tektites. The K-T boundary is recorded in numerous sedimentary beds around the world. 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.

Since both the ash beds and the tektites occur either at or very near the K-T boundary, as determined by diagnostic fossils, the tektites and the ash beds should be very nearly the same age, and they are Table 2.

There are several important things to note about these results. First, the Cretaceous and Tertiary periods were defined by geologists in the early s.

The boundary between these periods the K-T boundary is marked by an abrupt change in fossils found in sedimentary rocks worldwide. Its exact location in the stratigraphic column at any locality has nothing to do with radiometric dating — it is located by careful study of the fossils and the rocks that contain them, and nothing more.

Furthermore, the dating was done in 6 different laboratories and the materials were collected from 5 different locations in the Western Hemisphere. And yet the results are the same within analytical error. These flows buried and destroyed Pompeii and other nearby Roman cities.

We know the exact day of this eruption because Pliny the Younger carefully recorded the event. They separated sanidine crystals from a sample of one of the ash flows. Incremental heating experiments on 12 samples of sanidine yielded 46 data points that resulted in an isochron age of 94 years.

The actual age of the flow in was years. Is this just a coincidence? No — it is the result of extremely careful analyses using a technique that works. This is not the only dating study to be done on an historic lava flow. Two extensive studies done more than 25 years ago involved analyzing the isotopic composition of argon in such flows to determine if the source of the argon was atmospheric, as must be assumed in K-Ar dating Dalrymple26 flows; Krummenacher19 flows.

Note, however, that even an error of 0. Summary In 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.

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. Their odds of success are near zero. Even if against all odds they should succeed, it still would not prove that the Earth is young. Only when young-earth creationists produce convincing quantitative, scientific evidence that the earth is young will they be worth listening to on this important scientific matter.
