This volume is the monograph concerning digs carried out on the burial sites of Ohh Min, Htan Ta Pin, Nyaung Gon, Hton Bo and Ywa Gon Gyi between 2005 and 2010. It associates an exhaustive description of all graves explored (methods of burial and accompanying grave goods) with the detailed inventory of all remains found on the sites. Syntheses and specialized analyses carried out in laboratory conditions complete the data. They enable us to put forward theories concerning the evolution of cultures in the River Samon basin during the Iron Age, demonstrating their integration and their originality within the neighbouring groups in South-East Asia.
