Compiled cross-section through Site 4 (Delémont-En La Pran), constructed from the field and laboratory data collected from the site area. The sedimentary sequence includes Late Glacial and Early Holocene deposits and also palaeochannels filled between about 2,000 and 400 cal BC (legend in Fig. 6). The archaeological layer was formed during the Bronze and Iron Ages and constitutes a marker horizon all along the A16 motorway (height exaggerated by a factor of 10). The local stratigraphy and sedimentology (ringed numbers) is described in detail in Online Resource 4
