Recent Advances in Models of Siliciclastic Shallow-Marine Stratigraphy
Siliciclastic shallow-marine deposits record the interface between land and sea, and its response to a variety of forcing mechanisms: physical process regime, the internal dynamics of coastal and shelfal depositional systems, relative sea level, sediment flux, tectonic setting, and climate. These deposits have long been the subject of conceptual stratigraphic models that seek to explain the interplay between these various forcing mechanisms, and their preservation in the stratigraphic record. This volume arose from an SEPM research conference on shoreline–shelf stratigraphy that was held in Grand Junction, Colorado, on August 24–28, 2004. The aim of the resulting volume is to highlight the development over the last 15 years of the stratigraphic concepts and models that are used to interpret siliciclastic marginal-marine, shallow-marine, and shelf deposits.

Shelf turbidite bodies have long been recognized in ancient rock successions, but most examples are poorly constrained both by the limited outcrop exposures and by the lack of modern analogues or data. Uncertainties include the mechanism or mechanisms responsible for generating the turbidites, the mode of transport onto and across shelf, the relationship to time-equivalent shoreface deposits, and the resulting three-dimensional sand-body geometry or sedimentary architecture. This study takes advantage of the exceptional outcrop exposures in the Book Cliffs of eastern Utah to answer some fundamental questions regarding the origin and distribution of shelf turbidite bodies. The lower Kenilworth...
