Flaser and lenticular deposits (sensu Reineck and Wunderlich) are common in the sedimentary record and generally found associated with rippled seafloors in

A form of bedding, characterized by cross-laminations draped with silt or clay, which forms 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.

Lenticular bedding would be coded as 3X3 and wavy bedding would be coded as 3X2.5. sample 2.15 - flaser and lenticular bedding - Download Free 3D model by UQ School of Earth and Environmental Sciences (@UQ_SEES) [67fd211] The wavy orientation of the streaks indicate flaser-type ripple bedding. Interbedded sandstone and shale (layered) ( 322.5 ) in core. Note that shale interbeds between sandstone beds are thicker than in previous core. Flaser bedding of non-tidal origin has been described from point bar deposits of the Ajay river, NE India. Mud drapes are deposited during waning flood phases. The preferential accumulation of curled, desiccated mud laminae in ripple troughs during periods of exposure produces mud streaks resembling classical flaser bedding.

Flaser bedding

While flaser beds typically form in tidal environments, they can (rarely) form in fluvial conditions - on point bars or in ephemeral streams. [1] 2021-03-31 · 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 can be subdivided according to how the mud is deposited over the rippled sand.
