Absolute radiometric dating is the application of a scientific

A few principles were recognized and specified later.

An early summary of them is found in Charles Lyell's .

To get to that point, there is also a historical discussion and description of non-radiometric dating methods.

It can't float in mid-air, particularly if the material involved is sand, mud, or molten rock.

In this situation, the cave contents are younger than both the bedrock below the cave and the suspended roof above.

However, note that because of the "principle of cross-cutting relationships", careful examination of the contact between the cave infill and the surrounding rock will reveal the true relative age relationships, as will the "principle of inclusion" if fragments of the surrounding rock are found within the infill.

I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists.

Geochronologists do not claim that radiometric dating is foolproof (no scientific method is), but it does work reliably for most samples.

In no way are they meant to imply there are no exceptions.
