SEQUENCE STRATIGRAPHY

Transgression

The process where the shoreline shifts landward due to factors like sea level rise.

Shoreline shift landward

Occurs during transgression, often accompanied by features like estuaries.

Retrogradational pattern

Characterized by a fining upward sequence where deep facies are found at the top and shallow facies at the bottom.

Estuaries

Coastal bodies of water formed at the transition between river and ocean, significant in transgressional processes.

Sea level rise

An increase in the level of the world's oceans due to melting ice caps, among other factors.

Falling stage tract

A feature that occurs due to a rapid decrease in sea level, typically associated with forced regression.

Regression

The process where the shoreline shifts seaward due to either sedimentation or sea level fall.

Normal regression

A type of regression where the shoreline shifts seaward due to sedimentation.

Forced regression

A type of regression where the shoreline shifts seaward due to a rapid fall in sea level.

Falling stage system tract (FSST)

Represents a phase of rapid fall in sea level, associated with forced regression.

Low stand system tract (LST)

Early stage of regression when sea level starts to rise after being low.

Transgressive system tract (TST)

Occurs during a rapid rise in sea level, indicating a transgression.

High stand system tract (HST)

Occurs during the last stages of a rise in sea level.

Sedimentation

The process of sediment accumulation which can lead to normal regression.
