Shorefaces - Trace Fossils as Indicators of Sedimentary Environments - page 576

FIGURE 16 Conceptual model proposed for shoreface deposits. The top ternary diagram is modi-
fied after Dalrymple et al. (1992) and Dashtgard et al. (2009) , showing the relative position of tidally
modulated shorefaces (the tidal end member of shorefaces) with respect to wave, tide, and river
influence on sediment deposition. The middle ternary diagram is developed strictly for shorefaces
and considers the three main influences on sediment deposition in these settings: fair-weather (FW)
waves, storm waves, and tides. The lower diagram considers only tidal processes (currents and tidal
range) and their influences on shoreface character. Modified after Dashtgard et al. (in press).
