Perhaps a good place to start this article would be to affirm that radiometric dating is not inaccurate. To understand this point, we need to understand what exactly is being measured during a radiometric dating test.It is certainly incorrect, and it is certainly based on wrong assumptions, but it is not inaccurate. One thing that is not being directly measured is the actual age of the sample.Since coal is relatively incompressible, Gentry concludes that these particles of uranium and polonium must have entered the deposit before it turned to coal.These isotope ratios are sensitive to the temperature at the time they fell as snow from the clouds.After this was widely accepted, further studies of the rocks brought the radiometric age down to about 1. The rate of decay is proportional to the number of parent atoms present.If all the argon escaped from hot lava of volcanoes that erupted long ago, then all the argon should escape from the hot lava of volcanoes that erupt in modern times too.
For example, it has been known since the s that the famous Cretaceous-Tertiary boundary, the line marking the end of the dinosaurs, was 65 million years old.
