Flaser bedding is a sedimentary structure characterized by alternating rippled sand and discontinuous mud layers created by the deposition of mud on previously existing sand ripples. Similarly, wavy bedding consists of alternating rippled sand and mud layers, but with thicker, more horizontally continuous mud layers than in flaser bedding .

flaser bedding A form of heterolithic bedding characterized by cross-laminations draped with silt or clay. Flaser beds form in environments where flow strengths fluctuate considerably, thus permitting the transport of sand in ripples, followed by low-energy periods when mud can drape the ripples.

The sand formations within the bedding display a 'lens-like' shape, giving the pattern its respected name. They are commonly found in high-energy environments such as the intertidal and supratidal zones. Flaser bedding, vertical section. 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.

Bhattacharya, A. (1997): On the origin of non-tidal flaser bedding in point  (1968): Classification and origin of flaser and lenticular bedding. This rock contains wavy, flaser, and lenticular beds along with trace fossils, desiccation  The three main types of heterolithic bedding are flaser, wavy, and lenticular. Starved ripples and cross bedding with flasers can also  Heterolithic bedding: flaser and wavy types In 61 A, flaser bedding predominates in the central sand body, passing to lenticular bedding both upwards and  bedding, herringbone cross-bedding, lenticular bedding, and mud/silt couplets are common to both the environments. In fact, flaser bedding and lenticular bedding are more common in the point bar facies In a wavy laminated unit, a fin A thick succession with lenticular and lenticular-like bedding is described from the nation, wavy bedding, erosional channels, raindrop imprints, etc., suggest de REINECK, H. E. 1960: Uber die Entstehung von Linsen- und Flasersch Differences between flaser, wavy and lenticular beddings.

I Õ 1 3. Flaser, Wavy and Lenticular Bedding The process of alteration of bed load and suspension sedimentation gives rise to variety of flaser, wavy and lenticular bedding. The differentiation of these types of structures is controlled however; by the relative volume of sand and mud, by the re- f.

Lenticular bedding: Lenses of sand in a muddy matrix. Although these can occur in many subaqueous environments, they are particularly characteristic of tidally dominated ones, where there is daily variation in flow regime.

Graded Bedding . Evenly Laminated Sand and Horizontal Bedding . Coarsely Interlayered Bedding .

Rhythmites of v.f.g sand and carbonate mud contain abundant stacked, wavy, lenticular and flaser bedding in a well-sorted and segregated silt and clay that.

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 that they also form in fluvial environments 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 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): 1 Cross‐bedding with flasers. 2 Flaser bedding, subdivided 2016-08-29 · Flute casts - how to use them as a way-up (younging) direction indicator in sedimentary rocks - Duration: 1:27. GeoHub Liverpool 469 views Lenticular bedding is classified by its large quantities of mud relative to sand, whereas a flaser bed consists mostly of sand.

8A); alternation of sandstone and mudstone laminae that form lenticular, wavy and flaser bedding (Fig. The sedimentary structure mainly includes unidirectional and bidirectional cross bedding, interference and curved ripple mark, and wavy, flaser and lenticular bedding. 16.

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).

Flaser, wavy, and lenticular bedding indicate alternation of bedload transport due to tidal currents and suspension fallout during slack-water periods (Reineck and Wunderlich, 1968; Klein, 1971). Upward replacement of tractive bedforms (i.e., current ripples) by mud deposited from suspension indicates decreasing tidal energy, which is consistent with progressive shallowing.

Lenticular Sandstone | Description Flaser Bedding These tiny wavy beds of mudstone with lenticular pods of sandstone are typical of delta sediments. The pound coin is for scale. The classification contains the following main bedding types and intermediary types (Fig.1): 1 Cross‐bedding with flasers.
