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.

FLASER - What does FLASER stand for? The Free Dictionary. which creates sedimentary structures such as flaser, wavy and lenticular beddings (Fig. Interpretation. Flaser and lenticular bedding form in an environment of alternate periods of current or wave activity and slack water (Reineck & Wunderlich 1968). As pointed out by de Raaf&Boersma (1971), flaser and len ticular bedding commonly indicate tidal action although the … flaser in British English.

Wavy bedding: Roughly equal volumes of sand and mud. Lenticular bedding: Lenses of sand in a muddy matrix. The sedimentary structure mainly includes unidirectional and bidirectional cross bedding, interference and curved ripple mark, and wavy, flaser and lenticular bedding. 16.

They may also be produced by episodic flooding on the alluvial plains, or weak storms in the offshore environments, but their primary occurrence is in tidal settings where the regular presence of slack tides favors mud deposition ( Reineck and Singh, 1980 , Dalrymple, 2010 ). Definitions.
