Absolute dating is the process of determining an age on a specified chronology in archaeology Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge The technique often cannot pinpoint the date of an archeological site better than historic records, but is highly effective for. Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that Measuring Radiocarbon – AMS vs Radiometric Dating.
Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50, years, and most rocks of interest are older than that. Carbon dating is used by archeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50, years.
Because of the short length of the carbon half-life, carbon dating is only accurate for items that are thousands to tens of thousands of years old. Most rocks of interest are much older than this.
