Flaser bedding Flaser bedding: Sand alternates with small drapes of mud. Wavy bedding: Roughly equal volumes of sand and mud. 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,

The classification contains the following main bedding types and intermediary types (Fig.1): 1Cross-bedding with flasers. Footage of Sedimentary Structures known as Lenticular and flaser bedding in geology. Geology - Sedimentary Bedding Structures. Geology these Sedimentary Bedding Structures were deposited by water. Drought Mudcracks or desiccation cracks. Types of heterolithic beddings Differences between flaser, wavy and lenticular beddings White = sand/sandstone Black = mud/shale (Reineck & Wunderlich, 1968) FLASER BEDDING Lenticular Bedding Wavy Bedding INTRODUCTION Discontinuous ripples or lenses (in the vertical and Quoting Reineck and Wunderlich (1968), the Glossary of Geology (Bates and Jackson, 1987, 3rd edn.) defines the term “flaser structure” as “ripple cross-lamination in which mud streaks are preserved in the troughs but incompletely or not at all on the crests” (p. 246).The term “lenticular bedding” is defined as “a form of interbedded mud and ripple cross-laminated sand, in which In 61 A, flaser bedding predominates in the central sand body, passing to lenticular bedding both upwards and downwards.

GeoHub Liverpool 469 views 2021-04-11 · 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. Flaser bedding: Sand alternates with small drapes of mud. Wavy bedding: Roughly equal volumes of sand and mud. Lenticular bedding: Lenses of sand in a muddy matrix.

Lenticular Sandstone | Description Flaser Bedding These tiny wavy beds of mudstone with lenticular pods of sandstone are typical of delta sediments.

4 . Lenticular bedding with thick or flat lenses, subdivided in: (a) continuous lenticular bedding (with connected lenses); (b) broken lenticular bedding (with single lenses). The result is lenticular/wavy or flaser bedding depending upon the mud to sand ratio (Reineck and Wunderlich, 1968; Wang, 2012). The discontinuous sand lenses resemble lenticular bedding, hence, 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.

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. Flaser bedding would generally be coded as 5X3.5 in the Ferm classification.

Upon an upward-fining succession, (1) regular changes vertically from flaser bedding, through wavy bedding and to lenticular bedding are diagnostic of most of

They are commonly found in high-energy environments such as the intertidal and supratidal zones.
