Sedimentological analysis shows that the deposits have been formed under the influence of fluvial and tidal processes in the shallow-water environment, at least partly as infilling of erosional channels, thus evidencing deltaic or estuarine settings.
In contrast, in the Emsian at Willwerath, also in the Rhenish Slate Mountains of Germany, Parahughmilleria lived in a shallow, brackish or freshwater terrestrial setting in a deltaic transitional facies, possibly a floodplain lake or interdistributary lagoon (Poschmann and Tetlie 2006).

Based on the typical geologic section on recently deposited soils of the Yangtze delta plain in the southern area of Jiangsu province, from the bottom up, sediment strata are divided into riverbed facies, washland-firth facies and deltaic facies sediment, including medium sand, fine sand and sandy clay with horizontal bedding and cross bedding.
Sediment distribution in the paddock and the sedimentary structures can be described as a deltaic model (Reineck and Singh 1975; Reading 1978).
