radiometric dating issues

How reliable is radiometric dating?

The reliability of radiometric dating is subject to three unprovable assumptions that every geologist must make when using the radioactive “clock”. Radioactive rocks offer a similar “clock.” Radioactive atoms, such as uranium (the parent isotopes), decay into stable atoms, such as lead (the daughter isotopes), at a measurable rate.

What is a radiometric date?

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.

Why is crystallization a problem for radiometric dating?

This is not necessarily a problem for radiometric dating, because it can be taken into account. But as we saw above, processes that take place within magma chambers involving crystallization could result in a different concentration of uranium and thorium at the top of a magma chamber than at the bottom.

What are the assumptions of radioactive dating?

The assumptions on which the radioactive dating is based are not only unprovable but plagued with problems. As this article has illustrated, rocks may have inherited parent and daughter isotopes from their sources, or they may have been contaminated when they moved through other rocks to their current locations.

What is the most common radiometric dating method?

One common radiometric dating method is the Uranium-Lead method. This involves uranium isotopes with an atomic mass of 238. This is the most common form of uranium. It decays by a 14-step process into lead-206, which is stable. Each step involves the elimination of either an alpha or a beta particle.

What is a radiometric date?

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.

What are the limitations of radiometric dating?

The shortcomings of the radiometric dating method is one of many indications that our earth is only a maximum of 10,000 years old and was created by God. Another problem that calls into question the credibility of radiometric dating is heat contamination.

What is uranium lead radiometric dating used for?

Uranium–lead radiometric dating involves using uranium-235 or uranium-238 to date a substances absolute age. This scheme has been refined to the point that the error margin in dates of rocks can be as low as less than two million years in two-and-a-half billion years.

What are the assumptions of radiometric dating?

The field of radiometric dating persists despite these mountains of assumptions. Each calculation assumes universal constants that are assumed, constant decay rates that are assumed, and original conditions, including those assumed.

How are radioactive rocks dated?

Radioactive rocks offer a similar “clock.” Radioactive atoms, such as uranium (the parent isotopes), decay into stable atoms, such as lead (the daughter isotopes), at a measurable rate. To date a radioactive rock, geologists first measure the “sand grains” in the top glass bowl (the parent radioisotope, such as uranium-238 or potassium-40).

Can radiometric dating be used to date sedimentary rocks?

There is a discussion of a few examples of radiometric methods with sedimentary rocks in Mythology of Modern Dating Methods. Creationists believe that the assumptions of radiometric dating are invalid and cannot be proven.

Should we trust radioactive age clocks?

Not Billions (Master Books, Green Forest, Arkansas, 2005), pages 65–78. If these clocks are based on faulty assumptions and yield unreliable results, then scientists should not trust or promote the claimed radioactive “ages.” The assumptions on which the radioactive dating is based are not only unprovable but plagued with problems.
