GDE
gross depositional environment
causes of transgression and regression
transgression-rise in sea level causes coastline to shift landwards
regression-Stationary sea level, with adequate sediment supply, causes coastline to shift basinwards. Fall in sea level also causes regression, but with more abrupt upwards increase in grain size.
