Late Quaternary Mississippi River Incised Valley Fill: Transgressive Depositional Packages
… in reentrenchment of the Mississippi River incised valley. Meltwater floods from proglacial lakes incised into older deposits followed by braided fluvial (substratum) aggradation due to reduced carrying capacity after floods followed by meandering fluvial(topstratum aggradation as fluvial …

Evolution and Architecture of an Incised Valley in the Upper Cretaceous Eagle Formation in South-Central Montana
… establish a three-phase depositional history of valley evolution: 1)fluvial incision during decreasing accommodation concomitant with fluvial deposition and sediment storage on abandoned terraces within the valley, 2) rapid increase in accommodation significantly outpaced sediment influx …

High Resolution Facies & Architectural Analysis of a Tributive, Basal Terrace of a Ferron Compound Incised Valley
… the identification and description of the major valley surfaces and associated deposits of a compound incised valley that forms much of the base of Sequence 1 throughout the area. The oldest valley terrace, of what are thought to be three constituent valleys formed during a stepped relative fall …

Optimizing geo-cellular reservoir modeling in a braided river incised valley fill: Postle field, Texas County, Oklahoma
Includes bibliographical references (pages 123-130).

Aspects of Cyclic Sedimentation in the Upper Mississippian, Mauch Chunk Group, southern West Virginia and southwest Virginia
… within the Mauch Chunk Group are multiple incised-valley fills and a distinctive prodeltaic succession of laminated sandstones and mudstones. Calculated estimates of drainage basin areas for incised-valley fills in the Mauch Chunk Group range from > 1,000,000 km2 for the Stony Gap Sandstone …

Caracterização morfológica-sedimentar do vale inciso Apodi-Mossoró e plataforma continental adjacente - Bacia Potiguar Offshore
Systems of incised valleys have been studied in different continental shelves, including the Brazilian continental margin. The interest to characterize this feature is given by the information that it can provide variations on sea level, as well as the ability to host economically significant …

Depositional Environments and Sequence Stratigraphy of Upper Mississippian Strata in the Central Appalachian Basin
… character of dominant facies include: 1) major incised valley-fill to coastal plain, 2) major incised valley-fill to deltaic, 3) minor incised valley-fill, 4) coastal plain, and 5) marine-dominated sequences. Transgressive and highstand deposits within several sequences contain tidal rhythmites. …

Analysis of a Middle Pennsylvanian Channel Complex in Pikeville, Kentucky
… of fluvial architectural elements within an incised valley. A photo-mapping of the channel elements helped to identify major facies, and to interpret different autocyclic and allocylic factors. Backstripping revealed true dimensions of the units and magnitude of local subsidence. When the …

Valley Widening and the Composite Nature of Valley Margin Sequence Boundaries: Evidence from the Neilson Wash Compound Valley Fill, Cretaceous Ferron Sandstone, Utah
Incised valleys are at the center of a debate about whether sequence boundaries are chronostratigraphically significant. Current research has suggested that the sequence boundary that makes up the floor and walls of an incised valley is constantly being modified throughout the entire relative …

Reservoir characterization and prediction of the Lower Cretaceous Glauconite Member at Jenner-Suffield Field, Alberta, Canada.
… level rise following an episode of lowstand paleovalley incisement. Borehole data were used to identify petrofacies within the Glauconitic Member and characterize their controls on reservoir quality, production characteristics, and petrophysical attributes for facies prediction. Analysis of …

Depositional systems, sequence architecture, and controlling factors of an Eocene stratigraphic sequence at Minfeng steep margin of Dongying depression, eastern China
… sequence boundaries, as perched lake and incised valley. Their infills are interpreted as fan-lacustrine deposition and fluvial-shoreface-deltaic-lacustrine deposition, recording variable sedimentation during lake lowstand and early expansion. The development of two contrasting …

SEDIMENTOLOGY, ICHNOLOGY, AND SEQUENCE STRATIGRAPHY OF THE MIOCENE OFICINA FORMATION, ORINOCO OIL BELT, EASTERN VENEZUELA BASIN
… fluvial braidedchannel deposits filling an incised valley. No evidence of marine conditions is present and the only biogenic structures detected are root trace fossils present at the top of a few fining- and thinning- upward channelized units. The Middle Member is much more heterogeneous, …

Architectural Models for Lower Pennsylvanian Strata in Dickenson/Wise County, Southwest Virginia: A Reservior Case Study
… of upward-fining lowstand and transgressive incised valley fill, alluvial, and estuarine deposits, and upward-coarsening highstand deltaic deposits and represent 4th-order sequences. Lowstand and transgressive deposits are separated from the highstand deposits by marine flooding zones …

Apparent weekly and daily earthquake periodicities in the western United States, and evolution of Wadi Kubbania in Egypt
… the modern Nile to the Western Desert over the valley known today as Wadi Kubbania. This study addresses two hypotheses. The first hypothesis advocates that Wadi Kubbania was a morphologically incised valley of the pre-Eonile River where uplift of the Nubian swell may have forced rapid erosion …
