Across the strike of the foreset beds of the delta, this contact shows altitude variations of the order of 2 to 3 m. These variations are considered to result from high- and low-tide fluctuations in sea level during construction of the delta. These structures are of use in distinguishing between marine and non-marine volcanic deltas, to indicate tidal range, and to provide information about flow rate of the lava and, hence, a minimum time for the formation of pillow lava/hyaloclastite deltas.
