During the last two decades the radiocarbon (14C) dating of hydroxyapatite archaeological cremated bones has become standard practice. Various pretreatment procedures exist among different laboratories of which some include fixation of SO2 using “Sulfix” prior to CO2 reduction. Recently it was reported that the use of Sulfix may cause the resulting 14C age to be too old. Here we report on the use Sulfix at the Aarhus AMS Centre. Further, we report on an experiment designed to test alternatives for the use of Sulfix as a purification agent.
The multi-stratified site of Túrkeve-Terehalom presents an exceptional opportunity to establish the start and the end of the Middle Bronze Age in the Eastern Carpathian Basin and to refine its inner chronology. The chronological potential of the site rests on the meticulous excavation campaigns over a decade. This potential has been harvested by linking stratified finds, particularly pottery, to narrow, calibrated age-ranges. The result has implications for local chronology while also prompting questions about how to synchronise long-range connectivity with central and northern Europe and the Aegean, as well. The resulting chronological model for Túrkeve-Terehalom firstly challenges prevailing chronological views regarding the life-spans of Bronze Age structures with beaten clay floors, secondly the direction of the wave of destruction and/or abandonment of multi-stratified sites in the Carpathian Basin, and thirdly the continental networking during the Middle Bronze Age.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
