Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating , as use of the word “absolute” implies an unwarranted certainty of accuracy. In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates coins and written history.

Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics. In historical geology , the primary methods of absolute dating involve using the radioactive decay of elements trapped in rocks or minerals, including isotope systems from very young radiocarbon dating with 14 C to systems such as uranium—lead dating that allow acquisition of absolute ages for some of the oldest rocks on Earth.

Radiometric dating is based on the known and constant rate of decay of radioactive isotopes into their radiogenic daughter isotopes. Particular isotopes are suitable for different applications due to the types of atoms present in the mineral or other material and its approximate age. For example, techniques based on isotopes with half lives in the thousands of years, such as carbon, cannot be used to date materials that have ages on the order of billions of years, as the detectable amounts of the radioactive atoms and their decayed daughter isotopes will be too small to measure within the uncertainty of the instruments.

One of the most widely used and well-known absolute dating techniques is carbon or radiocarbon dating, which is used to date organic remains. This is a radiometric technique since it is based on radioactive decay. Carbon moves up the food chain as animals eat plants and as predators eat other animals. With death, the uptake of carbon stops. It takes 5, years for half the carbon to change to nitrogen; this is the half-life of carbon

Chronometric dating has revolutionized archaeology by allowing highly accurate dating of historic artifacts and materials with a range of scientific techniques. Chronometric dating, also known as chronometry or absolute dating, is any archaeological dating method that gives a result in calendar years before the present time. Archaeologists and scientists use absolute dating methods on samples ranging from prehistoric fossils to artifacts from relatively recent history.

Scientists first developed absolute dating techniques at the end of the 19th century. Before this, archaeologists and scientists relied on deductive dating methods, such as comparing rock strata formations in different regions. Chronometric dating has advanced since the s, allowing far more accurate dating of specimens. Adrian Grahams began writing professionally in after training as a newspaper reporter.

Argon or fluorine deficiency is a disorder which may cause increased dental caries or tooth radiocarbon, is the breakdown of dental tissues by the acidic methods released by the “bacterial fermentation of radiometric carbohydrates.

Radiocarbon dating also referred to as radiocarbon dating or carbon dating is a method for determining the age of an carbon containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late argon at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric method.

The resulting 14C combines with absolute oxygen to form radiometric carbon dioxide, which is incorporated into methods by photosynthesis; animals then acquire 14C by eating the plants.

Having an accurate time scale is a crucial aspect of reconstructing how anatomical and behavioral characteristics of early hominids evolved. Relative dating methods allow one to determine if an object is earlier than, later than, or contemporary with some other object. It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years.

The most common relative dating method is stratigraphy. Other methods include fluorine dating, nitrogen dating, association with bones of extinct fauna, association with certain pollen profiles, association with geological features such as beaches, terraces and river meanders, and the establishment of cultural seriations. Cultural seriations are based on typologies, in which artifacts that are numerous across a wide variety of sites and over time, like pottery or stone tools.

If archaeologists know how pottery styles, glazes, and techniques have changed over time they can date sites based on the ratio of different kinds of pottery. This also works with stone tools which are found abundantly at different sites and across long periods of time. Stratigraphic dating is based on the principle of depositional superposition of layers of sediments called strata.

This principle presumes that the oldest layer of a stratigraphic sequence will be on the bottom and the most recent, or youngest, will be on the top. The earliest-known hominids in East Africa are often found in very specific stratigraphic contexts that have implications for their relative dating. These strata are often most visible in canyons or gorges which are good sites to find and identify fossils.

Understanding the geologic history of an area and the different strata is important to interpreting and understanding archaeological findings.
