Potassium argon dating reliability

Published: 22.01.2018

As far as I know, no study has been done to determine how different methods correlate on the geologic column excluding precambrian rock. Lava flows that lie above and below rock beds with ancient human fossils are a good—and true—example.

This is a well founded major assumption, common to all dating methods based on radioactive decay. Archived from on potassium argon dating reliability.

And if we recall that most radiometric dating is done of igneous bodies, one sees that the percentage of anomalies is meaningless. This could move the "ages" to tremendously high values. Musk ox muscle was dated at 24, years, but hair was dated at 17, years. Some gave virtually zero ages, although the geologic evidence suggested that devitrification took place shortly after the formation of a deposit. Interesting insights are likely to come from such a group. This is consistent with a young world—the argon has had too little time to escape. The forms issued by radioisotope laboratories for submission with samples to be dated commonly ask how old the sample is expected to be.

Other ore bodies seemed to show similar evidence.

To make matters even worse for the claimed reliability of these radiometric dating methods, these same basalts that flowed from the top of the Canyon yield a samarium-neodymium age of about million years, 5 and a uranium-lead age of about 2.

Rubidium decays to strontium. These techniques are applied to igneous rocks, and are normally seen as giving the time since solidification. One can assume that at the beginning of the flood, many volcanoes erupted and the waters became enriched in Ar

The J factor relates to the of the neutron bombardment during the irradiation process; a denser flow of neutron particles will convert more atoms of 40K to 40Ar than a less dense one.

Musk ox muscle was dated at 24, years, but hair was dated at 17, years. Radiation from atomic testing, like cosmic rays, causes the conversion of 14 N to 14 C. The partial pressure of argon should be largest deepest in the earth, and decrease towards the surface.

      This happens quite fast, yet so much helium is still in some rocks that it has not had time to escape—certainly not billions of years.

      It is subtracted, and a proportional amount of the 38 Ar and 40 Ar are also subtracted. Significant quantities of argon may be introduced into a mineral even at pressures as low as one bar.

      One can also hypothesize that leaching occurred. There is not absolutely reliable long-term radiological "clock".
