Quantifying Downstream, Vertical and Lateral Variation in Fluvial Deposits: Implications From the Huesca Distributive Fluvial System

Quantifying sedimentary deposits is crucial to fully test generic trends cited within facies models. To date, few studies have quantified downstream alongside vertical and lateral variations distributive fluvial systems (DFS), with most reporting qualitative trends. This study reports on the generation of a quantitative dataset Huesca DFS, Ebro Basin, Spain, in which downstream, channel characteristics are analyzed using fusion field data virtual outcrop model derived (VOM). Vertical trend analysis reveals that exposed portion DFS does not show any systematic changes through time, suggests autogenic-driven local variability. Proximal-to-distal from display decrease average body thicknesses (13.1–0.7 m), deposit percentage (70–4%), storey (5.2–0.7 m) confirm observed other DFS. The VOM shows similar all characteristics. range values are, however, larger due increase amount can be collected, thus less clear. therefore highlights standard techniques do capture variability present outcrops. Channel was found variable (37% variation) medial setting, whereas thickness (?15 m range) proximal setting. Storey varied both settings (range 9 11 for respectively) becoming more consistent downstream. Downstream shifts architecture also noted massive, highly amalgamated channel-body sandstones regions isolated or offset-stacked channel-bodies dominating distal region. Trends explained by spatial processes preservation potential. overlap indicates no single value representative position has important implications interpreting location point sits when limited (i.e., log) datasets. These comparative results contribute improving accuracy system-scale predictions characteristic subsurface deposits.
