Radiometric dating sedimentary
The assumptions which underlie radiometric dating are covered in our radiometric dating article published here.his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional 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.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.
For example, the principle of superposition is based, fundamentally, on gravity.
Sedimentary rock on the other hand consists of sedimentary particles which were removed and deposited somewhere else by some sort of fluid (generally wind and water).
The sedimentary particles predate the rock which they form.
Dating the particles which make up the rock wouldn’t give you the age of the rock itself.
In addition, the redeposition process upsets the conditions necessary to achieve accurate results through radiometric dating.
