For example, the principle of superposition is based, fundamentally, on gravity.

In order for a layer of material to be deposited, something has to be beneath it to support it.

These are often characterised as the norm, rather than the exception.

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.

6) Two separate isotopes were measured in a rock to determine its age. Because the radiometric isotopes are not reset when the clastic sedimentary rocks are formed.

Most of these principles were formally proposed by Nicolaus Steno (Niels Steensen, Danish), in 1669, although some have an even older heritage that extends as far back as the authors of the Bible.

A few principles were recognized and specified later.

The layers of rock are known as "strata", and the study of their succession is known as "stratigraphy".

Fundamental to stratigraphy are a set of simple principles, based on elementary geometry, empirical observation of the way these rocks are deposited today, and gravity.
