Isotopes dating archaeological finds
Our strongly methodological research philosophy is therefore capable of pointing the way for more applied case study work within the archaeometrical community. Jan Elsen, geologist Bert Neyt, and archaeologist Dennis Braekmans (all K. Leuven), diverse options for geo-archaeological research utilizing radiogenic isotopes were discussed with respect to the field situation: 1.) The metal and glass artifacts and building stones and wall veneer excavated at Sagalassos reflect a great range of different raw materials and commodities used for their production.
As with lead, local sources for copper and metals alloyed with it are unknown on the territory and can be excluded.
At Sagalassos, one finds a mixture of artifacts produced both from local materials available on the territory and imported raw materials.
While the "internal" isotopic characterization of these artifacts is not a problem, there is a clear lack of isotopic background data for comparison.
The amount of carbon 14 will decay at a fixed rate so, by measuring the amount of carbon-14 compared with carbon-12, scientists can know how old it is.
Isotope Archaeology: July 8-20, 2007 Radiogenic isotope archaeology at Sagalassos--perspectives from the field situation: Radiogenic isotopes are of major importance in the Earth Sciences for numerical dating of rocks and the study of various geological processes, such as the origin of magmas, the sources of metals concentrated in ore deposits, the composition of ancient seawater, etc.Archaeologists can use isotopes for various things including dating artifacts, understanding where artifacts come from (such as what region animals were raised in, or where resources were mined) and reconstructing past dietary habits.
