Sequence stratigraphy and facies associations / Секвенс-стратиграфия и фациальные ассоциации

There has been a proliferation in recent years of applications of sequence-stratigraphic concepts since the publications by Vail eta!. (1977a,b), Posamentier eta!. ( 1988), Posamentier and Vail ( 1 988a,b) and Van Wagoner et a!. ( 1 990). The use of this approach to enhance understanding of geological relationships within a time-stratigraphic framework clearly has achieved widespread acceptance. Along with the rapid acceptance of these concepts, however, has come a number of problems that are addressed in this paper.
The inevitable introduction of a morass of terminology as well as occasional misunderstanding and misapplication of the stratigraphic model has led to considerable confusion. Moreover, certain key contentious issues within sequence stratigraphy remain that need to be resolved. Most importantly, however, sequence stratigraphy must be viewed as a tool or approach rather than a rigid templ ate. The conceptual stratigraphic models are based on first p rinciples and it is the understanding of these first principles rather than memorization of the model that is the key to successful application of sequence stratigraphy
