The implication of the technology and chronology reflected in the metal assemblage from the middle-class Xiongnu burials at Tamiryn Ulaan Khoshuu, Mongolia

Bronze and iron objects from the middle-class Xiongnu burials at Tamiryn Ulaan Khoshuu were examined for technology and chronology. The bronze objects were made from copper–tin–lead alloys, mostly for ornamental purposes, while the iron objects were household items made of cast iron. Radiocarbon measurements dated the site to the 4th century bce to the 1st century ce. The results revealed two key factors: (1) Xiongnu style material culture established by incorporating various contributions from across Eurasia at an earlier date than previously supposed; and (2) the emergence of regionally stratified material culture suggesting intimate political relationships consistently maintained between geographically distant Xiongnu communities.
