I wonder, what about granitic intrusions, or Plutonic rocks? We would only want to measure the amount of Calcium 40 that is produced when K 40 is broken down, and not the natural Ca 40 in the rocks that would contaminate our measurements.

Potassium is a radioactive isotope of potassium that decays into argon Another name for plutonic rocks is intrusive igneous rocks.

What Are Two Methods Used To Date Fossils?

The data does not support long ages. So since the time of the flood, there is no evidence that there has been any change in half-lives of radioactive materials. Potassium-argon dating Written By: I don't see why creationists can't accept the age of the earth as being older than what a book written thousands years ago says as interpreted by pope usher.

      If the surrounding medium contained high Argon pressure, the molten rock would then accept Argon gas by allowing the Argon gas to reach equilibrium with its surrounding medium. Note that time is expressed in millions of years on this graph, as opposed to thousands of years in the C graph.
