accommodation:
space available for potential sediment accumulation between the seafloor
or land surface and sea level or lake level (Jervey, 1988).
aggradation:
building up of the Earths surface by deposition (e.g., the
upbuilding by a stream to establish or maintain uniformity of grade or
slope) (Bates and Jackson, 1987).
chronostratigraphic:
pertaining to the organization of rock strata into units on the basis
of their age or time of origin (Bates and Jackson, 1987).
depositional
facies: 3-D rock assemblage representing sediments
deposited in specific depositional environments by similar sedimentary
processes.
eustasy:
worldwide sea-level regime and its fluctuations, caused by absolute
changes in the quantity of seawater (Bates and Jackson, 1987).
lithofacies:
rock assemblage distinguished on the basis of lithology, sedimentary
structures, and stratification style.
progradation:
building forward or outward toward the sea of a shoreline or coastline
(Bates and Jackson, 1987).
regression:
retreat or contraction of the sea from land areas and the resulting changes
that bring nearshore environments to areas formerly occupied by offshore
environments (Bates and Jackson, 1987).
relative
sea level: position of the sea surface relative to a fixed
datum near the seafloor. Changes result from both eustasy and vertical
movements of the seafloor (Posamentier and Allen, 1999).
retrogradation:
landward movement or retreat of a shoreline or coastline (Bates and
Jackson, 1987).
strandplain:
a prograded shore built seaward by waves and currents (Bates and Jackson,
1987).
subsidence:
sinking or settling of part of the Earths surface with little
or no horizontal movement (Bates and Jackson, 1987).
systems tract:
a linkage of contemporaneous depositional systems (Brown and Fisher,
1977).
