Sequence Stratigraphy

Abstract

Sequence stratigraphy relies upon grouping sediments into discrete packages based upon the relative sea-level regime during the time of their deposition. In so doing it has revolutionised the way we understand the stratigraphic record. The technique significantly aids correlation allowing disparate data to be integrated effectively and dramatically improves predictive capability. This has been used to greatest effect in the hydrocarbon exploration industry to increase the economic success of exploration by successfully predicting the pre-drill presence of source rocks, reservoirs and seals. Recent studies have revealed fast paced, high amplitude global sea-level (eustatic) cycles even in intervals of time considered to be greenhouse climate states, which can be linked to warming and cooling trends. Understanding the driver for these enigmatic events is an important avenue for future research and may help with our predictions of the characteristics of an anthropogenically forced greenhouse world.
