Abstract
In July through October 2014, the Joint Hulun Buir Archaeological Team organized by the Institute of Archaeology, CASS and other institutions conducted excavation to the Gangga Cemetery in Chen Barag Banner. This cemetery covering an area of about 2ha was located on the riverbank terrace about 6km to the east of Hoh Nor Town and about 600m to the south of the mainstream of the Hailar River. The excavated area is 680sq m, from which 16 burials were recovered. All of the burials had wooden burial receptacles, most of which were log coffins, and some of them were furnished with wooden board coffins. The grave goods unearthed from these burials included pottery wares, wooden saddles, birch bark quivers, iron arrowheads, bronze belt ornaments, agate beads, etc. The date of Gangga Cemetery was around the 8–10th centuries CE, which is significantly valuable for the exploration of the origination of the Mongol ethnic group.
