Sequence stratigraphy

Sequence stratigraphy is the study of rock relationships within time-equivalent depositional successions bounded by surfaces of erosion or nondeposition. An interruption in sedimentation (discontinuity) is commonly accompanied by a period of erosion that can cause a significant gap in the rock record (unconformity).   In sequence stratigraphy, unconformities define the ends of depositional sequences and the beginnings of new sequences.

Sequence stratigraphy can be used as a lithological predictor and as a tool for unraveling basin-fill history. High resolution sequence stratigraphy is useful in petroleum reservoir correlation and modelling.
