Prehistoric combustion structures are a consequence of the economic and social conditions of past communities. Through the study of the “social life” of a combustion structure of the SBUS (simple basin structure with unconstrained stones) type, which are abundant in the archaeological record of the Iberan northeast, specifically in the Barcelona Plain, this paper will explore the degree of implantation and consolidation of neolithic societies in their surrounding territory. Thanks to the close collaboration between rescue archaeologists and university specialists, a systematic collection of high-resolution analytical techniques was carried out for the combustion structure (EC2) located at Carrer Aurora (Raval archaeological site, Barcelona). Our deployed toolset includes geological, archaeomagnetic, archaeobotanical, microspatial, micromorphological and biochemical analyses. This is the first time this type of approach has been applied to a combustion structure from the northeastern coast of the Iberian Peninsula to better understand their process of construction, use and abandonment.
