Systems tracts are composed of all deposits accumulating during one phase of relative sea level cycle and preserved between specific primary chronostratigraphic surfaces.<ref name=ch04r23>Brown, L., F., Fisher, W., L., 1977, Seismic-stratigraphic interpretation of depositional systems: examples from Brazilian rift and pull-apart basins, in Payton, C., E., ed., Seismic Stratigraphy—Applications to Hydrocarbon Exploration: AAPG Memoir 26, p. 213–248.</ref> Erosion usually dominates the falling phase of a sea level cycle, and the deposited sediments are most often assigned to the lowstand systems tract.
