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.
Methods of dating rocks Absolute dating involves determining a rock’s actual age as a number of years, whereas relative dating methods provide an estimate of the age of a rock by comparing it to rocks of a known age The Geological Time Scale has been created by combining both absolute and relative dating methods.
Radioactive or radiometric dating is a very important method of determining an absolute age for a rock using radioactive isotopes.
This group is dedicated to providing information about the scientific method as it concerns the idea of evolution in the Creation/Evolution debate.
Ask yourself how the things that are happening in the world today might end up being recorded in the sediments that are now or soon will be deposited.Check out this video on the Uranium – Lead dating method: Biostratigraphy is a relative dating method that correlates rock ages using the fossils contained within rock units.Knowing this first: that scoffers will come in the last days, walking according to their own lusts, and saying, “Where is the promise of His coming?The rate at which the isotopes decay is in effect our "geological clock".By measuring the amount of the parent and daughter isotopes in a crystal, and then applying the decay rate, the actual age in years since the rock crystallized can be calculated.
