Abstract
This paper provides an updated view of the chronology of and cultural complexes present in the Bampur Valley, south-eastern Iran, during the Chalcolithic period (fifth and fourth millennia BC). It is based on a reexamination of ceramic assemblages from six sites located in this valley investigated by Aurel Stein in the 1930s—assemblages that are held by the Peabody Museum at Harvard University—and comparisons with additional available data from the south-eastern Iranian Plateau during this period.
