Shoreline shift landward
Retrogradational pattern- fining upward
Feature name - Estuaries
Sea level rise
Deepening upward (Deep facies found at the top whereas shallow facies found at the bottom)
Transgressive system tract found - due to rapid increase in sea level
Shoreline shifts seaward
either due to sedimentation - Normal regression
due to sea level fall - Forced regression
Regression is of two types
1) Normal regression
Shoreline shift seaward due to sedimentation
Low stand system tract, High stand system tract
2) Forced regression
Shoreline shift seaward due to rapid fall in sea level
Falling stage system tract - rapid decrease in sea level
Fining upward - Retrogradational pattern
1) FSST - Rapid fall in sea level : Forced regression
2) LST - Sea level just start rising (initial stage when sea level start rises)
3) TST - rapid rise in sea level : Transgression (retrogradation pattern)
4) HST - Last stages of rise in sea level (progradation pattern)
