Shelf-margin Systems Tract
Aggradation Aggradational Parasequence Set Lowstand Systems Tract Progradation Progradational Parasequence Set Retrogradation Retrogradation Parasequence Set Trangressive Surface Type 2 Sequence Boundaries	The lowermost Systems Tract, and is associated with a type 2 sequence boundary and a low relative position in sea level. Base bounded by a type 2 unconformity, and top by the transgressive surface. Base exhibits the downward stepping stacking patterns of prograding clinoforms capped by backstepping onlapping retrogradational aggrading clinoforms that thicken upwards.
