Sequence Stratigraphy
Reading
Transgression
shoreline moves
landward
due to relative sea level rise
shoreline moves to place where previously there was land
Regression
due to
sedimentation
(addition more sediment)
seaward
movement shoreline
Forced Regression
due to
relative sea level fall
seaward movement shoreline
Evidence
Relative sea level & sedimentation
from characteristics of sediment packages
Sedimentary facies begets
water depth / position vs shoreline
Relative sea level change
change in water depth at a point
poss causes
crustal uplift / subsidence
increase/decrease water volume
sediment addition
