Potassium 40 dating problems

These each have 19 protons and 21 neutrons in their nucleus.

If one of these protons is hit by a beta particle, it can be converted into a neutron.

Both the physical geologists and paleontologists could point to evidence that much more time was needed to produce what they saw in the stratigraphic and fossil records.

As one answer to his critics, Kelvin produced a completely independent estimate -- this time for the age of the Sun.

was published, the earth was "scientifically" determined to be 100 million years old. In 1947, science firmly established that the earth was 3.4 billion years old.

Finally in 1976, it was discovered that the earth is "really" 4.6 billion years old… The answer of 25 million years deduced by Kelvin was not received favorably by geologists.

From June 6-8, 2017, our New Mexico Geochronology Research Laboratory will host 35 geochronologists from 7 countries to discuss multiple topics that impact radiometric dating of rock samples and noble gas measurements.

The isotopes the KAr system relies on are Potassium (K) and Argon (Ar).

One out of every 10,000 Potassium atoms is radioactive Potassium-40 (K-40).His result was in close agreement with his estimate of the age of the earth.The solar estimate was based on the idea that the energy supply for the solar radioactive flux is gravitational contraction.Potassium-Argon Dating Potassium-Argon dating is the only viable technique for dating very old archaeological materials.Geologists have used this method to date rocks as much as 4 billion years old.Motivation for the question to follow: Some of the common mistakes we make in evaluating claims are resisting contrary evidence, looking for confirming evidence, and preferring available evidence.
