“…Attempts to recognize "conventional" systems tracts, which are tied to base-level cycles, are inappropriate unless components of the fluvial succession can be correlated with marine successions downstream (e.g., Kerr et al, 1999;Figure 27). The responses of fluvial systems to allogenic forcing are complex, and have been reviewed elsewhere (e.g., Summerfield, 1985;Pitman and Golovchenko, 1988;Butcher, 1990;Miall, 1991;Schumm, 1993;Zaitlin et al, 1994;Ethridge et al, 1998;Holbrook and Schumm, 1998;Blum and Törnqvist, 2000;Catuneanu and Elango, 2001;Holbrook, 2001). …”

It has been accepted for inclusion in Papers in the Earth and Atmospheric Sciences by an authorized administrator of DigitalCommons@University of Nebraska -Lincoln. AbstractSequence stratigraphy emphasizes facies relationships and stratal architecture within a chronological framework. Despite its wide use, sequence stratigraphy has yet to be included in any stratigraphic code or guide. This lack of standardization reflects the existence of competing approaches (or models) and confusing or even conflicting terminology. Standardization of sequence stratigraphy requires the definition of the fundamental model-independent concepts, units, bounding surfaces and workflow that outline the foundation of the method. A standardized scheme needs to be sufficiently broad to encompass all possible choices of approach, rather than being limited to a single approach or model.A sequence stratigraphic framework includes genetic units that result from the interplay of accommodation and sedimentation (i.e., forced regressive, lowstand and highstand normal regressive, and transgressive), which are bounded by "sequence stratigraphic" surfaces. Each genetic unit is defined by specific stratal stacking patterns and bounding surfaces, and consists of a tract of correlatable depositional systems (i.e., a "systems tract"). The mappability of systems tracts and sequence stratigraphic surfaces depends on depositional setting and the types of data available for analysis. It is this high degree of variability in the precise expression of sequence stratigraphic units and bounding surfaces that requires the adoption of a methodology that is sufficiently flexible that it can accommodate the range of likely expressions. The integration of outcrop, core, well-log and seismic data affords the optimal approach to the application of sequence stratigraphy. Missing insights from one set of data or another may limit the "resolution" of the sequence stratigraphic interpretation. 1 2 c a t u n e a n u e t a l . i n e a r t h -science r e v i e w s 92 (2009)

“…An increased rate of accommodation creation is commonly attributed to one or more of the following driving mechanisms: (1) high rates of basin subsidence such as encountered in many foreland basin settings (e.g. Marenessi et al 2005); (2) base-level rise (Bristow et al 1999;Bourquin et al 2006) Most systems are governed by a combination of these factors, although one may be dominant (Ethridge et al 1998). …”

Prediction of channel connectivity and fluvial style in the flood-basin successions of the Upper Permian Rangal coal measures (Queensland)

Predicting the presence and connectivity of reservoir-quality facies in otherwise mud-prone fluvial overbank successions is important as such sandbodies can potentially provide connectivity between larger neighboring sandbodies. This interseam. Well spacing was too great to allow accurate correlation of channel bodies. The Ob River, Siberia, was used as modern analogue to supply planform geometric measurements of splay and distributary channels, so that stochastic modeling of channel bodies was possible. The resulting models demonstrated that (i) channel-body connectivity is more uniform in distributary river systems than in splay complexes; (ii) relatively good connectivity is seen in proximal positions in splays, but decreases distally from the source as channel elements diverge; (iii) connectivity tends to be greater down the axis of splays, with more isolated channel bodies occurring at the margins.

“…Afforestation during the last few decades of much of the hill country, the elimination of annual burning practices, and the implementation of erosional controls in the rivers have promoted aggradation, offset to some extent by gravel extraction processes, and a longer term degradational phase (as noted above). In a geological context, sedimentation is controlled by the interplay of three factors: (1) control of the basin's eastern margin; (2) climatic changes; and (3) changes in sea level (Ethridge et al 1998). Considerable debate exists over the relative importance of these controls on the nature and architecture of fluvial deposits (Cloetingh 1991;Schlager 1993;Shanley & McCabe 1994).…”

Clast size characteristics of gravel within rivers of the Waimea Plains, Nelson

Gravel within rivers of the Waimea Plains near Nelson, New Zealand, was derived through the Wairoa Gorge from Paleozoic-Mesozoic basement rocks to the southeast, and to a lesser extent from Pleistocene gravels to the west. A downstream reduction of mean clast size and an increase in sorting occurs in three rivers of the Waimea Plains. Clast form is dominated by bladed clasts, with a slight tendency with transport distance to more elongate forms. Clast sizes are apparently larger in the modern rivers than in fluvial gravels of the Last Glacial period. The smaller clast size in the Last Glacial deposits may indicate more efficient clast-size reduction in glacial as opposed to modernday rivers.
