Compositional, micromorphological and geotechnical characterization of Holocene Tiber floodplain deposits (Rome, Italy) and sequence stratigraphic implications

This study reports a high-resolution micromorphological characterization of floodplain deposits to investigate the relationships among compositional, textural and geotechnical data, integrate soil micromorphology with sequence stratigraphy. Compositional facies associations features are calibrated against parameters. The latter, obtained from cone penetration pocket penetrometer tests borehole advanced 60 m into Tiber channel belt floodplain, show that depositional post-depositional modifications intrinsically associated test parameters: resistance; sleeve friction; friction ratio. Petrographic document pedogenetic across stratigraphic markers evidenced by faunal plant activity, accumulation peat, typified precipitation heavy metals, iron oxides secondary carbonates. All these developed in correspondence alluvial flooding surfaces correlated non-marine marine recognized transgressive highstand coastal lagoonal Depositional Sequence. These observations may serve as model reconstruct sequence-stratigraphic evolution ancient relict soils. Nevertheless, additional criteria (for example, their position correlative surfaces) necessary adequately interpret genesis such low-rank surfaces. work demonstrates combination between sedimentological can be critical supplement field determine relative effect pedogenic processes on organization, composition texture, properties urban areas.
