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.When exposed to water that contains fluoride, a fluoride ion (F-) can replace a hydroxyl ion (OH-) in the bone mineral.The resulting fluor-apatite is more stable than the original form, thus the fluoride content of a bone will increase over time if it is exposed to a solution containing fluoride ions.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.

Wind and water erode strata and some areas are uplifted or even tilted.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.This dating method is also known as Archaeological Dating or Historical Chronology. These methods were relied on especially prior to the introduction of scientific methods of dating.But, even when the scientific methods of absolute dating are available, this method of dating has not lost its importance, as many a time we have to depend solely on relative dating.In such cases subjective element cannot be ruled out.
