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, 1991; Lyman et al., 2012).
Is fluorine analysis relative dating?
Fluorine analysis can be used only as a relative dating method because the rate of decay and the amount of dissolved minerals in the ground water varies from site to site. In other words, the biochemical clock that this method relies on runs at a different rate in different environments.
What is relative and absolute dating?
Relative age is the age of a rock layer (or the fossils it contains) compared to other layers. Absolute age is the numeric age of a layer of rocks or fossils. Absolute age can be determined by using radiometric dating.
How does fluorine analysis work?
Fluorine absorption dating is a method used to determine the amount of time an object has been underground. Items such as bone that are in the soil will absorb fluoride from the groundwater over time. From the amount of absorbed fluoride in the item, the time that the item has been in the soil can be estimated.
What is the fluorine dating method?
Definition. Fluorine dating is a method that measures the amount of fluoride absorbed by bones in order to determine their relative age. 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.
How often should you see someone you date?
Although seeing them once a week is fine, if you want to see them more by month four you can scale it up to twice depending on your schedule. She recommends seeing each other weekends and a mid-week visit.
How do I know if I have fluoride in my water?
How can I tell if my water has fluoride in it? Your water system publishes a consumer confidence report each year and makes that report publicly available. The report is often available on the internet, but you may need to contact your water provider to request a copy.
