SUMMARY. Ripple, flaser and lenticular bedding are well known, but for describing profiles, they are not sufficiently defined and subdivided. It is, therefore, the intent of the following text to present such a definition and classification.
Sedimentary structures common (but not limited) to tidal-dominated deposits include: Flaser bedding and anastamosing shales. Lenticular sands. Bi- directional
of flaser subfacies (F), wavy subfacies (W) and lenticular subfacies (L) at L7. [B] Ripple mark structures on the every single beds of sandstone at L23. [C] Cross-lamination (i) and parallel lamination (ii) structures at L7. [D] The ichnofossils that found in the heterolithic facies: i- Skolithos, ii- Chondrites, iii-Ophiomorpha, iv-Thalassinoides. The three main types of heterolithic bedding are called flaser, wavy, and lenticular. Flaser bedding is characterized by cross-laminated sands with thin mud Upon an upward-fining succession, (1) regular changes vertically from flaser bedding, through wavy bedding and to lenticular bedding are diagnostic of most of Flaser bedding: Sand alternates with small drapes of mud. · Wavy bedding: Roughly equal volumes of sand and mud.
The classification contains the following main bedding types and intermediary types (Fig.1): 1 Cross‐bedding with flasers. 2 Flaser bedding, subdivided in: (a) simple flaser bedding; (b) bifurcated flaser bedding; (c) wavy flaser bedding; (d) bifurcated wavy flaser bedding. 3 Wavy bedding. 4 Lenticular bedding with thick or flat lenses, subdivided in: (a) continuous lenticular bedding (with connected lenses); (b) broken lenticular bedding (with single lenses).
Lenticular laminated shales occur from the Precambrian (e.g., Schieber et al. 2007a) onward (e.g., Wignall 1994). Flaser and wavy bedding are often characterized as important sedimentary structures in synthesis papers on tidal and estuarine deposition (e.g. Clifton, 1982, Elliott, 1986, Boggs, 1995), yet these structures are rarely discussed in synthesis papers on fluvial deposition (e.g. Collinson, 1986, Miall, 1992, Boggs, 1995), despite the recognition Lenticular filter housing is the outer cover of the lenticular filtration system that protects the inner filtering elements.
246).The term “lenticular bedding” is defined as “a form of interbedded mud and ripple cross-laminated sand, in which

It ranges from flaser to lenticular bedding in nature F8-Muddy sand heterolithics Repetitive alternations of fine sand and shale laminae The fine sand and silt laminae range from millimeter-thick
Lenticular bedding is classified by its large quantities of mud relative to sand, whereas a flaser bed consists mostly of sand.

Lenticular and flaser bedding: Depending on the relative proportion of sand and mud you have lenticular mud and flaser bedding Lenticular - mainly mud and occasional sand being supplied an that is moved as ripples in. high velocity - they preserve as ripples encased in mud Wavy bedding - even breakdown of mud and sand Flaser bedding - mostly sand ripples. Flaser and lenticular deposits (sensu Reineck and Wunderlich) are common in the sedimentary record and generally found associated with rippled seafloors in tidally influenced coastal waters. These features are thought to be created by deposition of suspended fine-grained mud onto a rippled sandy seafloor during quiescent periods, followed by migration of sand ripples during periods of strong tidal currents. sample 2.15 - flaser and lenticular bedding - Download Free 3D model by UQ School of Earth and Environmental Sciences (@UQ_SEES) [67fd211] Flaser and lenticular deposits (sensu Reineck and Wunderlich) are common in the sedimentary record and generally found associated with rippled seafloors in tidally influenced coastal waters.

Coarsely Interlayered Bedding . 2012-06-19 · Flaser and lenticular bedding 2562 httpsmeorhakifwordpresscom20120619 basic from AA 1 Flaser definition: a type of pattern or structure in sedimentary rock, caused by intermittent flows within | Meaning, pronunciation, translations and examples The heterolitic sediments record tidal influence by means of mud drapes, lenticular and flaser bedding and most probably represent deposition in interdistributary bays (e.g., Elliot, 1974; Wright, 1985). FLASER is listed in the World's largest and most authoritative dictionary which creates sedimentary structures such as flaser, wavy and lenticular Fig 3: Sandstone with wavy shale layers (flaser) (core sample).
