Rome in its setting. Post-glacial aggradation history of the Tiber River alluvial deposits and tectonic origin of the Tiber Island - Fig 2

<p>(<i>A</i>) Composite cross-section along a principal transect perpendicular to the alluvial valley of the Tiber River (yellow trace in inset b), showing stratigraphic logs of the 11 boreholes performed for this study in the Forum Boarium and of 4 boreholes previously drilled in the Sant’Omobono area [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0194838#pone.0194838.ref004" target="_blank">4</a>], with selected ¹⁴C and ceramic age constraints to sediment aggradation. Additional details on chronology are shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0194838#pone.0194838.s002" target="_blank">S2 File</a>. Blue lines are the tentative isochrone lines, defining three phases of sediment aggradation (arrows A, B, C) in the time span 5200–2200 yr BP. (<i>B</i>) Map showing location of the boreholes and the trace of the hypothesized faults.
