It is not about the theory behind radiometric dating methods, it is about their applicationand 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. To get type of dating used to determine the age of one fossil that point, there is also a historical discussion and description of non-radiometric dating methods. 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. 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 isbut it does work reliably for most samples. 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.
Chronological datingor simply datingis the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a "dating method". Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, historyarchaeologygeologypaleontologyastronomy and even forensic sciencesince in the latter it is sometimes necessary to investigate the moment in the past in which the death of a cadaver occurred. Dating methods are most commonly classified following two criteria: Relative dating methods are unable to determine the absolute type of dating used to determine the age of one fossil of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known. In this type of dating used to determine the age of one fossil dating method, Latin terms ante quem and post quem are usually used to indicate both the oldest and the most recent possible moments when an event occurred or an artifact was left in a stratum. But this method is also useful in many other disciplines. Historians, for example, know that Shakespeare's play Henry V was not written before because Shakespeare's primary source for writing his play was the second edition of Raphael Holinshed 's Chroniclesnot published until

Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.

Datingin geologydetermining a chronology or calendar of events in the history of Earthusing to a large degree the evidence of organic evolution in the sedimentary rocks accumulated through geologic time in marine and continental environments. To date past events, processes, formations, and fossil organisms, geologists employ a variety of techniques. These include some that establish a relative chronology in which occurrences can be placed in the correct sequence relative to one another or to some known succession of events. Radiometric dating and certain other approaches are used to provide absolute chronologies in terms of years before the present. The two approaches are often complementary, as when a type of dating used to determine the age of one fossil of occurrences in one context can be correlated with an absolute chronlogy elsewhere.
