Strontium Isotope Ratio (87Sr/86Sr) To Determine Human Skeletons Origins From The Ancient Cemeteries, Case study: An Iron Age Cemetery of Gohar Tepe

The isotopic analysis solves many important issues in archeology and anthropology including the reconstruction of past diets, tracing the footsteps of the ancient migrations and recognition of climate change. Stable isotope analysis has been applied in archaeology during the last three decades to address questions regarding the paleoclimatology, palaeodietary and palaeomobility. In this research, we focus on the human skeleton remains of Iron Age cemetery of Gohar Tepe, using Strontium stable isotope analysis to reconstruction the aspects of the past mobility. At the same time we tried to identify the geographical origin of people that buried in residential areas or ancient cemeteries. This approach in a geological region could make a substantial contribution to assess various aspects including migration models, cultural changes, colonialism and trade. Also research related to the palaeomigration has long been done by different analytical methods. Gohar Tepe is one of the areas that able to respond multiple questions about social and cultural developments of Iron Age in northern Iran. Tooth samples obtained from skeletons of the mentioned site where studied through Strontium isotope ratio (87Sr/86Sr) were used to address the question of whether the skeletons are local or non-local. Result of 87Sr/86Sr revealed that six of samples could be considered as local and five others to have been c as non-local.
