The second broad category is sometimes called "heavy-metal dating," and includes Uranium-Thorium-Lead, Rubidium-Strontium, and Potassium- Argon systems.
These are the methods that are commonly used on inorganic samples such as rocks, and that often give extremely long ages-millions or billions of years.
Nontechnical readers can skip the box-figures, however, without losing much.
Experimental Errors The methods that give ancient ages produce almost as many "wrong" answers as "right" ones.
It furnishes some good evidences that creationists often use.
But we won't discuss the C-14 method in this article.
And yet, there is really no scientific reason proving that radiometric dating is correct, and a number of evidences showing that it doesn't work. We'll find that faith in materialism, and rejection of any supernatural activity, is the foundation stone of radiometric analysis, even before any measurements are made.
The "correct" answer is chosen on the basis of stratigraphic sequences, that is, what kinds of fossils are buried nearby.
Of course, the fossil dates depend on the assumption of evolution.
" The only answer to that question is that "good" samples give dates that are in accord with evolutionary presuppositions.
"Bad" samples are the ones that give dates not in conformity with evolutions classic illustration of circular reasoning.5 Grand Canyon Dating Creationists have criticized many aspects of dating rocks by radioactivity, but have offered little real proof that the method is flawed.
