What can be inferred from imbrication in fluvial deposits?
Answer and explanation
Correct answer: Former stream-flow direction
Imbrication is the overlapping or preferred tilting of flat pebbles in a river deposit. Moving water commonly pushes these clasts so that their arrangement develops a consistent orientation related to the transporting current. Geomorphologists can therefore use imbrication to reconstruct the direction of former stream flow, although the precise interpretation should consider local bed conditions. Cave-roof height, tidal salinity, and dune age are not inferred from this structure. Option D is correct.
