Stratigraphic map.
A sequence stratigraphic surface is a type of stratigraphic contact that serves, at least in part, as a systems tract boundary ( Catuneanu et al., 2011 ). As systems tract boundaries, sequence stratigraphic surfaces mark changes in stratal stacking pattern between the units below and above the contact ( Fig. 11 ).
