Morphodynamic Hierarchy and the Fabric of the Sedimentary Record

Abstract: The low temporal completeness of fluvial strata could indicate that recorded events represent unusual and extreme conditions. However, field observations suggest that preserved strata predominantly record relatively common transport conditions—a paradox termed the strange ordinariness of fluvial strata. We theorize that the self‐organization of fluvial systems into a morphodynamic hierarchy that spans bed to basin scales facilitates the preservation of ordinary events in fluvial strata. Using a new probabilist… Show more

“…Recent quantitative research has focused on maximising the ability to accurately reconstruct the evolution of fluvial landscapes in the geologic past. Some efforts have centred on connecting landscape surface kinematics to stratal preservation (Paola & Borgman, 1991;Castelltort & Van Den Driessche, 2003;Jerolmack & Mohrig, 2005;Jerolmack & Paola, 2010;Hajek & Wolinsky, 2012;Ganti et al, 2013;Ganti et al, 2014;Reesink et al, 2015;Romans et al, 2016;Ganti et al, 2020;Straub et al, 2020) and a number of these studies have focused on Late Cretaceous fluvial strata in central Utah Trower et al, 2018;Ganti et al, 2019a). Meanwhile, other quantitative work has applied fluid and sediment transport models to stratigraphic field data, with an overarching goal of constraining the characteristics of catchments, regional systems or entire fluvial landscapes in the geological past (Ganti et al, 2019b;Lapôtre et al, 2019), or even on other planetary bodies (Lamb et al, 2012;Buhler et al, 2014;Hayden et al, 2019;Lapôtre et al, 2019).…”

“…It is noted that scaling relations that relate cross-set heights with original bedform heights (and subsequently formative flow depths) are derived from theory and experiments that assume statistical steady state, in which flow is constant (Paola & Borgman, 1991;Leclair, 2002;Jerolmack & Mohrig, 2005). As such, agreement of flow depth reconstructions with bar heights might therefore imply that these dunes were formed in steady flow conditions (Ganti et al, 2020). This contrasts with literature that alludes to the preferential preservation of dunes in unsteady flow conditions (Reesink & Bridge, 2007;Reesink & Bridge, 2009;Reesink et al, 2015;, and merits further work regarding the kinematic controls on dune preservation in this region.…”

“…Robust B bf estimates can inform empirical relations between channel width and the lateral migration rates of meandering rivers (Ielpi and Lapôtre, 2020). Equation 1 can also be used to quantify the extent of vertical preservation of formative bar topography, which encodes the relative time scales of channel migration and avulsion (Chamberlin and Hajek, 2019;Ganti et al, 2020). Thus, detailed measurements of the size and shape of preserved bars in fluvial strata can constrain the geometry and rates of ancient river evolution, which are central to unraveling fluvial responses to boundary condition perturbations on Earth and river mobility on Mars.…”

“…For example, the Selenga River delta has a σ range indicative of substantial distributary network reorganization following large and periodic earthquake-related displacements, and the same should be expected for similarly scaled systems. At these scales, reorganization may be recorded in the chemical and sedimentary stratigraphy of the delta (Dong et al, 2016) as unconformities and hierarchical packages that appear similar to autogenic avulsions (Ganti, Lamb, & Chadwick, 2019;Ganti, Hajek, Leary, Straub, & Paola, 2020). At the opposite spectrum end, the Mississippi River delta main-channel σ range indicates minor reorganization (Figure 5).…”
