Dating from archaeological

Bones and teeth, however, are primary archaeological materials and are common to many archaeological sites. Bones bearing cut marks from stone tools are a clear proxy for human occupation of a site, and in the study of human evolution, hominid remains provide the primary archive material. Hence, many attempts have been made to directly date bones and teeth using the U-series method. Unlike calcite, however, bones and teeth are open systems. Living bone, for example, contains a few parts per billion (ppb) of Uranium, but archaeological bone may contain 1-100 parts per million (ppm) of Uranium, taken up from the burial environment. Implicit in the calculation of a date from °Th/U or Pa/ U is a model for this Uranium uptake, and the reliability of a U-series date is dependent on the validity of this uptake model.

Did the plentiful use of lead cause severe outbreaks of lead poisoning in the Romans Archaeological chemists looking into this issue have examined skeletons dating from Roman times. Lead accumulates in the bones as the body absorbs this heavy element. The University of Minnesota researcher Arthur C. Aufderheide and his colleagues tested Roman... 

Archaeomagnetism can be considered a branch of Paleomagnetism specifically devoted to the dating of archaeological materials from the measurement of the remanent magnetization achieved by the iron oxide impurities present in clay after cooling of the ceramic artifact. This recording mechanism primarily provides information on the direction of the Earth s field at the time the artifact was fired or the kiln was last used. 

Cannabis use by humans dates from prehistoric times. It was used as a food source, medicine, fuel source, for fiber, and as a recreational drug. Although it is not known how Cannabis was first used, fibers and seeds have been found in Neolithic archaeological sites. Pottery... 

Radiocarbon dating of archaeological artifacts depends on the slow and constant production of radioactive carbon-14 in the upper atmosphere by neutron bombardment of nitrogen atoms. (The neutrons come from the bombardment of other atoms by cosmic rays.)...
