Radiometric dating is based on the decay rate of these isotopes into stable nonradioactive isotopes.
Despite very impressive and powerful measurement and characterization tools, physical and chemical analysis methods, the dating of rocks by using radioactive elements depends on very basic assumptions.
The significance and relevance of these assumptions have not been demonstrated.
Chronological dating, or simply dating, is 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".
Radiometric dating utilizes the decay rates of certain radioactive atoms to date rocks or artifacts.
