Eighty-seven subfossil bones found in soil at different locations in the province of Skåne, southern Sweden, were analysed for their fluorine content.
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.
The analytical results are compared with the chemical composition of the subsoil water in the area and radiocarbon dates of the bones.
The relationship between fluorine and silicon provides new information about the diagenesis of the inorganic phase of bone.
The term halogen means "salt-producing." When these elements react with metals, they produce a wide variety of salts, such as calcium fluoride, sodium chloride (common table salt), silver bromide and potassium iodide.
Iodine is the least reactive of the halogens as well as the most electropositive, meaning it tends to lose electrons and form positive ions during chemical reactions.
This is due to the fact that one or both of the objects may have been moved or redeposited into a different location.
It is best known for the vital role it plays in thyroid hormone production in humans as well as in all vertebrates.
Wind and water erode strata and some areas are uplifted or even tilted.
