Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which . Apr 30,  · A: Absolute dating is a method of determining the specific date of a paleontological or archaeological artifact or location based on a specific time scale or calendar.
