Fluorine absorption dating

Fluoride (or fluorine) dating is a relative dating method that can be used to date archaeological bone.As a relative dating method, it can determine the relative age of specimens, but cannot provide a calendrical date unless the fluoride chronology is calibrated with an absolute dating method.These processes result in All of these processes confuse the stratigraphic record.

Fluorine absorption dating can be carried out based on the fact that groundwater contains fluoride ions.

Although this can be compensated for by accommodating for the rate of absorption in calculations, such an accommodation tends to have a rather large margin of error.

In 1953 this test was used to easily identify that the 'Piltdown Man' was forged, almost 50 years after it was originally 'unearthed'.

Over time, buried bones pick up fluoride ions from soil moisture or exposure to groundwater.

Older specimens have higher fluoride contents than younger ones when burial conditions are identical.
