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.Fluoride ions are present in trace amounts in most soils and groundwaters.In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.Although relative dating can work well in certain areas, several problems arise.

process of absolute dating

Because all living organisms contain a radioactive form of carbon (carbon 14) that decays at a known and steady rate, archaeologists can determine an organic object's age (if it is less than 40,000 years old) by measuring the amount of carbon 14 remaining in the object.

Fluoride (or fluorine) dating is a relative dating method that can be used to date archaeological bone.
