Why are cross stratified conglomerates found in deposits of fan deltas? I know that fan deltas are alluvial fans that deposit directly into the sea, hence they are poorly sorted.But could not understand the reason for presence of cross stratified conglomerates.

  • $\begingroup$ It is typical in a delta to find cross bedding, and stratified sediments with a grainsize function of the flow event (seasonal flood, recession) or a stream getting a new flow path - so, fine to coarse alternations are common. Conglomerate is non-sorted. So you have a layer of conglomerate? And what above/under? $\endgroup$
