Fluorine dating is a method that measures the amount of fluoride absorbed by bones in order to determine their relative age. Unlike radiometric dating methods, it cannot provide a chronometric or calendrical date. Fluorine dating provides only a relative date for bone, revealing whether specimens are older or younger than one another or if they are of the same age Berger and Protsch, ; Lyman et al.
Fluorine dating relies on the discovery that bone mineral, calcium hydroxyapatite, will absorb fluoride ions if, during burial, it is exposed to groundwater that contains fluoride.

Interest in the origins of human populations and their migration routes has increased greatly in recent years. A critical aspect of tracing migration events is dating them. Inspired by the Geographic Population Structure model that can track mutations in DNA that are associated with geography, researchers have developed a new analytic method, the Time Population Structure TPS , that uses mutations to predict time in order to date the ancient DNA.
At this point, in its embryonic state, TPS has already shown that its results are very similar to those obtained with traditional radiocarbon dating. We found that the average difference between our age predictions on samples that existed up to 45, years ago, and those given by radiocarbon dating, was years.

It is a relative dating technique which compares concentrations of fluorine, uranium, or nitrogen in various samples from the same matrix to determine contemporaneity. Its range is , years to 1. The date on a coin is an absolute date, as are AD or BC. It is used for human and animal bone and other organic material.
Fluorine absorption dating is a method used to determine the amount of time an object has been underground. Fluorine absorption dating can be carried out based on the fact that groundwater contains fluoride ions. Items such as bone that are in the soil will absorb fluoride from the groundwater over time.

Relative Techniques. In the past, relative dating methods often were the only ones available to paleoanthropologists. As a result, it was difficult to chronologically compare fossils from different parts of the world. However, relative methods are still very useful for relating finds from the same or nearby sites with similar geological histories. The oldest and the simplest relative dating method is stratigraphy , or stratigraphic dating.

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s 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 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.
The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and from that point onwards the amount of 14 C it contains begins to decrease as the 14 C undergoes radioactive decay. Measuring the amount of 14 C in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.
The older a sample is, the less 14 C there is to be detected, and because the half-life of 14 C the period of time after which half of a given sample will have decayed is about 5, years, the oldest dates that can be reliably measured by this process date to around 50, years ago, although special preparation methods occasionally permit accurate analysis of older samples. Research has been ongoing since the s to determine what the proportion of 14 C in the atmosphere has been over the past fifty thousand years.
What is “fluorine dating”
Dating techniques are procedures used by scientists to determine the age of rocks, fossils, or artifacts. Relative dating methods tell only if one sample is older or younger than another; absolute dating methods provide an approximate date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element decays into a non-radioactive product at a regular rate.
Others, such as amino acid racimization and cation-ratio dating, are based on chemical changes in the organic or inorganic composition of a sample.
