Flaser beds are a sedimentary, bi-directional, bedding pattern created when a sediment is exposed to intermittent flows, leading to alternating sand and mud layers. While flaser beds typically form in tidal environments, they can (rarely) form in fluvial conditions - on point bars or in ephemeral streams. [1]

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. The best material for making the lenticular housing is stainless steel which exhibits very high tensile strength. A lenticular lens is a corrective lens type that requires a very high power to correct your vision.

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. The classification contains the following main bedding types and intermediary types (Fig.1): 1Cross-bedding with flasers. 2Flaser bedding, subdivided in 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. 2016-08-29 · Flute casts - how to use them as a way-up (younging) direction indicator in sedimentary rocks - Duration: 1:27.

Sub-tidal environments, tidal flats, back bay lagoons, deltas. Lower energy, more mud. Higher energy, more sand. FLASER vs. LENTICULAR. BEDDING

Wavy bedding contains equal amounts of sand and mud; therefore, the mud is draped around connected lens-like sandstone beds. The presence of wavy bedding suggests an equal dominance between high and slack tides (e.g., Allen and Johnson, 2010). Lenticular bedding 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 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). 2013-01-01 · Flaser, wavy and lenticular bedding is a gradational spectrum of heterolithic deposits with alternating beds/laminae of sand and mud.
