fluviomarine deposit

fluviomarine deposit:    Stratified materials (clay, silt, sand, or gravel) formed by both marine and fluvial processes, resulting from non-tidal sea level fluctuations, subsidence and/or stream migration (i.e., materials originally deposited in a nearshore environment and subsequently reworked by fluvial processes as sea level fell).

   Compare: estuarine deposit, lacustrine deposit, lagoonal deposit, marine deposit, overbank deposit.
