It was first used in 1862 as Hvarfig lera by the Swedish Geological Survey to describe rhythmically deposited light and dark clay layers in a proglacial environment on one of the first geological maps of Sweden. WebbTidal rhythmites are vertically accreted planar laminae that alternate between coarse and fine sediments forming couplets often composed of sands and muds. These deposits are characterized by bed/laminae thicknesses that vary rhythmically and preserve tidal periodicities, and are generally found in intertidal or subtidal depositional environments.

WebbSuch rhythmites are regarded to be the product of storm activities, with thin and laterally extensive sandstone facies that represents high energy storm events. The interbedded sandstones are characterised by very thin interbeds of siltstone and shale, and by non-parallel curved layers and truncation surfaces, which are characteristic of hummocky … Webbas rhythmites. The units are distinguished by the predominant clast size and contacts between the three units Qfcg, Qfg, Qfs, and Qglf are mostly indistinct. Mass-wasting deposits (Qmw) occurred during or shortly after catastrophic flood events, but they range in age up to the present. black and red moving background
