During the past decade, archaeological research in north-east Thailand has concentrated on the excavation of individual sites. Of these, the best known are Non Nok Tha (Bayard 1971) and Ban Chiang (Gorman and Charoenwongsa 1976). Both are relatively small occupation and burial sites, covering c. 1 ha and 3.5 ha respectively.
There have been several claims for an unexpectedly early bronze-working tradition in the area, and of the inception of iron technology during the second millennium BC. Biological remains from these sites reveal cultivation of rice and maintenance of domestic herds of cattle, pig and water buffalo (Gorman and Charoenwongsa 1976). While the recent surge of prehistoric research here and in adjacent areas has clearly demonstrated the presence of a south-east Asian bronze working tradition of some antiquity (Ha Van Tan 1980), the establishment of a chronological framework and of the settlement pattern in the area are in their infancy.
As part of the Thai Government's North-east Thailand Archaeological Project, steps were taken in 1980–81 to expand our knowledge of the Ban Chiang culture. During the 1980 dry season, Higham and Kijngam co-directed two intensive field surveys.
