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) 3 Wavy bedding. 4 Lenticular bedding with thick or into stacked flaser, wavy, and lenticular bedding of the heterolithic facies association. Layer-Thickness Analysis Layer-thickness and Fourier analyses of rhythmites are used extensively to test for and establish a tidal influence on sedimentation (e.g., Kvale et al., 1999; Williams, 1989; Hovikoski et al., 2005).

Flaser wavy lenticular bedding

The classification contains the following main bedding types and intermediary types (Fig.1): 1 Flaser bedding would generally be coded as 5X3.5 in the Ferm classification. The second digit would depend on the type of sandstone (4=gray, 5=crystalline, 6=hard). Lenticular bedding would be coded as 3X3 and wavy bedding would be coded as 3X2.5. Tide-genesis interpretation should be based on the balance of probabilities for any bedding types present in tidal settings and other environments (Dalrymple, 2010) and/or regular arrangement of a group of structures instead of a single bedding.

flaser, wavy and lenticular bedding, bimodal palaeocurrents and particular vertical arrangements of lithologies and structures, has provided evidence of intertidal

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.

The term “lenticular bedding” is defined as “a form of interbedded mud and ripple cross-laminated sand, in which the ripples or lenses are discontinuous not only in the vertical but also more or less in the horizontal direction” (p. 376), and the term “wavy bedding” as “a form of interbedded mud and ripple-cross-laminated sand, in

Layer-Thickness Analysis Layer-thickness and Fourier analyses of rhythmites are used extensively to test for and establish a tidal influence on sedimentation (e.g., Kvale et al., 1999; Williams, 1989; Hovikoski et al., 2005). The most distinctive sequences Location of Formation • flaser bedding - commonly forms in relatively high energy environments (sand flats) • wavy bedding - commonly forms in environments that alternate frequently from higher to lower energies (mixed flats) • lenticular bedding - commonly forms in relatively low energy environments (mud flats) Cross Stratification Variant 3: Structure caused by tidal (Flaser-Wavy 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).

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. The sand formations within the bedding display a 'lens-like' shape, giving the pattern its respected name.

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.

5 Flaser Bedding. Sandy Beds in which mud-drapes often preserve part of the bed form. Often whole ripple shapes are preserved in cross-section by a bed of Sedimentary structures include current ripples preserved as wavy beds, micro-cross-laminae, clay drapes, flaser bedding, lenticular bedding, and parallel lamination. The sequence consists of a basal scour overlain by graded, fresh volcaniclastic siltstone, resedimented limestone containing locally derived components interbedded with altered volcanic ash, and pelagic limestone consisting of Tb2 is characterized by flaser, wavy, and lenticular bedding and rare to common clay-lined burrows including Ophiomorpha nodosa.
