The common presence of unincised lowstand alluvial deposits is in stark contrast to the virtual absence of documented examples in the geologic literature. This study suggests that in tectonically quiescent areas, unequivocal extensive incised valleys form only if sea level fall is sufficient to fully expose the relatively steep gradient outer shelf and upper slope. Because of this, it is suggested that unincised lowstand alluvial deposits are far more common than heretofore realized. A reevaluation of published examples of incised valleys may reveal that some, if not many, are not, in fact, incised systems. Though both serve as conduits for sedimentary bypass, the reservoir architecture can be quite different, having significance for petroleum exploration and development.
