Modern dating techniques

My thanks to both him and other critics for motivating me.

Much of the Earth's geology consists of successional layers of different rock types, piled one on top of another.

It is not about the theory behind radiometric dating methods, it is about their , and it therefore assumes the reader has some familiarity with the technique already (refer to "Other Sources" for more information).

As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale.

A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.

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

This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.

his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale.

An early summary of them is found in Charles Lyell's .It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for "young Earth" theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques.This document is partly based on a prior posting composed in reply to Ted Holden.In the last 200 or more years of their application, they are valid, but geologists do not assume they are.
