lateral accretion

lateral accretion

[′lad·ə·rəl ə′krē·shən]
(geology)
The digging away of material at the outer bank of a meandering stream and the simultaneous building up to the water level by deposition of material brought there by pushing and rolling along the stream bottom.

'Facies classification using the seismic inversion and Scarab interpreted formation micro-imager (FMI) logs delineated the thick-bedded and thin-bedded gas sand encased in the bypassed remnant levees (RML and RSL) and in lateral accretion packages (LAPs) traps,' the article said.
The geometry of sandstone beds is mainly lenticular, channeled, with high erosive bases; but locally, they also form small and thin (up to 0.8 m thick) tabular to lateral accretion, sigmoidal sets, with relatively low erosional bases, that are laterally continuous for several tens of meters.
These inclined beds and surfaces are interpreted to have arisen via dominantly lateral accretion. They are usually considered as originated by meandering channels with sedimentation in the inside part of the meander, related to the fluvial-tidal transition (Dalrymple and Choi, 2007; Choi, 2010; Johnson and Dashtgard, 2014).
The presence of inclined bounding surfaces might also suggests the presence of lateral accretion geometry of the channel fill, but this is probably more apparent than real and related to channel belt aggradation.
(1989) present the floodplain as a relatively smooth riverbed adjacent to the minor one, formed in the last period of geological time (Last Glacial-Holocene) through the lateral accretion processes and vertical accretion, bounded by steep marginal (usually overhead terrace).
He is not afraid to criticise standard terminology, phenomena or concepts, which he maintains are often 'unrealistic' or 'unfortunate', or to criticise distinctions, such as the common distinction of channel deposits as 'lateral accretion' and floodplain deposits as 'vertical accretion'.
Projected drainage areas associated with horizontal well lengths drilled parallel to point bar lateral accretion growth directions (across clay drapes) suggest that horizontal well technology could significantly enhance production from these sands.
The next 1.5 m are mainly sand, arranged in lateral accretion units dipping 4-5[degrees].
The basal gravel, cut and fill, vertical decrease in grain size, lateral accretion bedding, and the suite of sedimentary structures described above all indicate that allomember 1 was deposited by a coarse-grained meandering fluvial system.
It is at once too narrow and too broad in different aspects of its research and argument: too narrow, because it does not offer an overarching, fully theorized account of all forms of performance (including nonelite) in which women engaged, and too broad because so much of its argument is created through lateral accretions. Because Tomlinson includes a much-neglected form of performance like music, she begs the question how other forms of "performance art" that cropped up shortly before the war and during the Interregnum would also have contributed to the acceptance of women as actors--in other words, why isolate singing from other dramatic skills like public declamation, street performance, political demonstrations, nontheatrical cross-dressing, and the like?
