==Lowstand systems tracts==
==Lowstand systems tracts==
The lowstand systems tract occurs between the basal sequence boundary and the transgressive surface. Lowstand systems are thickest toward basin centers because much of the basin margin is undergoing erosion. Lowstand systems with shelf-to-slope geometries may have basin center gravity-flow deposits due to sediment bypass of the slope and thick shelf-edge deltaic systems [[Depocenter#Sediment_supply_rate_and_facies_patterns|prograding]] into deep water. Fluvially dominated depositional systems are common.
