Most absolute age determinations in geology rely on radiometric methods. Radiometric datingradioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbonin which trace radioactive impurities were selectively incorporated when they were formed. All absolute isotopic ages are based on radioactive decaya process whereby a specific atom or isotope is converted into another specific atom or isotope at a constant and known rate. Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks. Generally, there are four main concepts that students struggle with when thinking about radioactive decay:.
