Abstract
Two different conceptual models underlie the application of sequence strati graphy by Exxon stratigraphers and later researchers. One, the global sea-l evel model (GSM), relates to presumed sea-level behaviour through time; the other, the sequence stratigraphic model (SSM), relates to the stratigraphi c record produced during a single cycle of sea-level change. Though the two models are inter-related they are logically distinct, and it is important to test them separately. A summary is presented of the nature of the two mo dels, and of the nomenclature that is used in their description. It is conc luded (a) that the global sea-level model comprises an assembly of local re lative sea-level events which are widely recognisable within their parent s edimentary basin; and (b) that the sequence stratigraphic model is robust, and its application is therefore an insightful way to approach the interpre tation of sedimentary rocks.
