Prior to the development of radiocarbon dating in the late s, archaeologists relied primarily on historical records and the position of archaeological finds to determine the relative order of past events. Today, there is a whole suite of dating methods derived from chemistry and physics that can determine the numerical age of the dated sample. Among these modern methods are radiometric dating techniques. Radiometric dating techniques are based on the principle that naturally occurring materials contain variants of particular chemical elements called isotopes , and some of these variants are unstable and undergo radioactive decay over time as the atoms transform into more stable forms. The time it takes for half of a given amount of an unstable isotope to decay is called half-life. Here are some radiometric dating methods that have been used at Liang Bua:.
