How accurate are radiometric dating methods?

They normally use radiometric dating methods to date the fossil, and many promote these methods as being accurate. Yet when you look into the technical papers on these discoveries, you find that these dates are often questionable and are sometimes clearly in error. What are radiometric dating methods?

Do all the different dating methods agree?

All of the different dating methods agree--they agree a great majority of the time over millions of years of time. Some make it sound like there is a lot of disagreement, but this is not the case.

What is the absolute dating method?

The absolute dating method first appeared in 1907 with Lord Rutherford and Professor Boltwood at Yale University, but wasn’t accepted until the 1950s. The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope.

Why do scientists reject all but the oldest dating methods?

Yet when asked why they reject all but the oldest science-based dating methods, the answer often given is that (they think) long-age radiometric dating is more reliable and that science settled the matter of the earth’s age many years ago.

Can all radiometric dating methods be wrong?

In regard to the radiometric dating of rocks, it is known that various different radiometric methods often yield quite discordant dates for the same rock, thus proving that they cannot all be correct.

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 is the most common radiometric dating method for uranium?

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.

How is radiometric dating used to date fossils?

Radiometric dating is based on the half-lives of the radioactive isotopes. These half-lives have been measured over the last 40-90 years. They are not calibrated by fossils.

Do relative dating methods provide an age in years?

They do not provide an age in years. Before the advent of absolute dating methods, nearly all dating was relative. The main relative dating method is stratigraphy. Stratigraphy is the study of layers of rocks or the objects embedded within those layers.

Why do scientists use multiple methods to date specimens?

Although certain dating techniques are accurate only within certain age ranges, whenever possible, scientists attempt to use multiple methods to date specimens. Correlation of dates via different dating methods provides a highest degree of confidence in dating.

Is there such a thing as an accurate dating technique?

In recent years, a few of these methods have come under close scrutiny as scientists strive to develop the most accurate dating techniques possible. Relative dating methods determine whether one sample is older or younger than another.

Do all the dating methods give similar dates?

If the dating methods are all objective and reliable, then they should give similar dates. The rocks were tested as whole-rock samples using K-Ar dating and also separated into individual minerals.
