Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.over the last half century nuclear science, radiography, chemistry and physics have developed laboratory procedures for determining accurately the absolute date of any stratigraphy.some of these methodologies are referenced in the other answers.there are several entries in wikipedia which provide good overviews of the question and numerous web sites that explain how to go about archaeological, paleontological and geological as dr.Can someone explain in short and/or provide a scientific paper talking about this topic?the basıc concept ıs stratigraphy: the earliest deposition is at thee top while the oldest is t the bottom. when you excavate you actually can see the layers of deposition as actual dating process is far beyond the scope of this venue but rather entails several graduate school courses in geochronolgy and Chronostratigraphy an excellent over view of dating in geology paleontology and archaeology may be seen at any particular excavation one must determine the key artifact, fossil and geological features, crating a relative chronology.musch below lists a series of dating techniques usd to determine the ags of fossils and artifacts.has shown that this bone dates back to 895-1017, which scientists from the University of Winchester believe ties in with the death of the two kings and is unlikely to have come from anyone apart from the father or the son.

But different isotopes have different numbers of neutrons.By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question.But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.

every stratum has its unique profile, whereby the relative chronology is verified.
