In recent years,with the development of archaeological investigations in Tibet,some important burials belonging to the Early Metal Age of Tibet have been discovered.Early iron tools are commonly present in these burials,which provide key evidence for further chronological study of the Early Metal Age of Tibet.This paper presents a chronological study of early iron tools excavated from the Piyang-Donga burials,suggesting that at the latest in the 5th century B.C.(and possibly as early as the 8th-7th centuries B.C.),Tibet had already entered the early Iron Age,with evidence of indigenous iron smelting no later than the 3rd century A.D.Comparing with evidence of iron artefacts from the surrounding areas,the iron technology in Tibet may have been introduced from Xinjiang and Kashmir.
