Radiometric dating metamorphic rocks


This would erroneously represent millions or billions of years of age.

It assumes radioactive decay has never been interrupted by worldwide cataclysmic events.

Scientists do not disagree with the amount of daughter isotopes found in rock formations, but rather the constancy of the rate of decay.

The third assumption is invalidated by discordant dates—that is, different dating techniques do not agree with each other or with known historic dates and by consistently finding vast ages from recently solidified magma.

This indicates that something is fundamentally wrong with the dating technique. Helens in 1980 provides a radioisotope age of 2.8 million years although the rock was only 15 years old, • Mt.

This would erroneously provide results in the millions or billions of years—and would thereby invalidate radioisotope dating techniques.
