Identify the advantages and disadvantages of carbon-14 uranium-238 and rubidium-87 dating

One rare form has atoms that are 14 times as heavy as hydrogen atoms: In the study of the Grand Canyon rocks by Austin, different techniques gave different results.

It does not give dates of millions of years and when corrected properly fits well with the biblical flood. Furthermore, different techniques should consistently agree with one another. The forms issued by radioisotope laboratories for submission with samples to be dated commonly ask how old the sample is expected to be. A relatively short-range dating technique is based on the decay of uranium into thorium, a substance with a half-life of about 80, years. The rubidium-strontium isochron technique suggested that the recent lava flow was Ma older than the basalts beneath the Grand Canyon—an impossibility. Rapid reversals during the flood year and fluctuations shortly after would have caused the field energy to drop even faster.

By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.

However, radioisotope dating may not work so well in the future. A particular isotope of a particular element is called a nuclide. If a material that selectively rejects the daughter nuclide is heated, any daughter nuclides that have been accumulated over time will be lost through diffusion , setting the isotopic "clock" to zero.

They realize that all science is tentative because we do not have all the data, especially when dealing with the past. That is how radiometric dating works.

Determining the Age of a Fossil Using Carbon-14

Luminescence dating methods are not radiometric dating methods in that they do not rely on abundances of isotopes to calculate age. A carbon-based life form acquires carbon during its lifetime. Thorium has a long half-life decays very slowly and is not easily moved out of the rock, so if the lead came from thorium decay, some thorium should still be there.

Zircon has a very high closure temperature, is resistant to mechanical weathering and is very chemically inert. A relatively short-range dating technique is based on the decay of uranium into thorium, a substance with a half-life of about 80, years. On impact in the cups, the ions set up a very weak current that can be measured to determine the rate of impacts and the relative concentrations of different atoms in the beams.

      Creationists cannot prove the age of the Earth using a particular scientific method, any more than evolutionists can.
