The use of pollen fossilization or in the case of man's influence with deforestation and the species introduction was so telling!
I learned a lot in such a short span of time, Thanks!
In many cases, however, it is possible to reconstruct the original sequence of strata so that they can be used for relative dating.
For instance, if we find a fossil bone below the strata 3 rock level shown above, we assume that the animal most likely lived at a time before that layer was formed.
The content of both fluorine and silicon in bone, as well as the Ca: (PO) molar ratio, are time-dependent, which means that these parameters seem to be suitable for dating purposes.
Methods and improvements are proposed in order to make chemical analysis and chemical dating of bone as reliable as possible.
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.
Unlike radiometric dating methods, it cannot provide a chronometric (or calendrical) date.The application of the described chemical dating method made it possible to discover the first Swedish and the oldest dated Scandinavian finds of wild horse, and one of the oldest finds of domestic cattle in Scandinavia.In the past, relative dating methods often were the only ones available to paleoanthropologists.Iodine is classified as a halogen — a subset of very chemically reactive elements (Group 17 on the periodic table) that exist in the environment as compounds rather than as pure elements.The other halogens include fluorine (F), chlorine (Cl), bromine (Br) and astatine (At).
