Abstract

Abstract: A unique type of blended mouth bars was recognized in middle-deep fan deltas in the western slope of Nanpu Sag, Bohai Bay basin. Combined with logging and seismic facies, and blended mouth bars' sedimentary features, the authors investigated bars' form, distribution patterns, and the genetic mechanisms by systematic view and analysis of cores from middle-deep beds of the research area. The results indicate that the lithology combination of the blended mouth bar shows an overall vertical upward sedimentary sequence consisting of multiple small reverse and positive compound cycles, the features of deposition from gravity flow. In a plane view, these blended mouth bars develop usually in front of underwater distributary channels of fan delta, and they present usually the forms of ligule or leaf. On the section, these blended mouth bars mainly show banded form, lute-shaped form, reversed lute-shaped form, and spindle-shaped form along depositional dip. These bars are independent lentoid sand body on perpendicular to source direction. These special blended mouth bars are quite different from the normal mouth bars on the basis of their characteristics, so they are called blended gravity flow bars.

Key words: fan delta, sandy debris flow, hyperpycnal flows, blended gravity flow bar, western slope of Nanpu Sag
