Loess
dune
It is a fine-grained unstratified accumulation of clay and silt deposited by the wind
The term "sediment" is generally used for eroded particles, but much more frequently for particles when they are deposited by water and ice. The terms dust and sand are more frequently used for the specific airborne particles. Or possibly loess which is a light-coloured fine-grained accumulation of clay and silt particles that have been deposited by the wind

Topsoil contains three types of soil particles: sand, silt and clay. Sand particles are coarse. Silt and clay particles are fine. Texture is used to describe the relative .. .
Soils deposited by a river or stream are known as alluvial soils. Alluvium may consist of coarse soil particles, such as sand and gravel, down to fine soil particles, like silt and clay. The lower the flow energy of the water, the finer particle sizes will settle.
Fine particles of fertile land that is deposited on the banks of a river after a flood
Loess is deposited by wind.
Either Aeolian deposits, or Loess.
Either Aeolian deposits, or Loess.
Loess deposits is form when sediment that is finer than sand, such as particles of clay and silt, is deposited into layers far from its source.

The reason many rivers contain clay is because clay particles are lighter than the small rocks and pebbles beneath, so the clay particles are deposited on top of the rocks. However clay is not lighter than silt particles, in fact clay is much heavier. Normally the silt would cover the clay, but if the river is fast enough, it may continue to carry away the silt particles, and leave the clay.
Larger particles are deposited first as a stream loses velocity. Gravel would be deposited first, since it is the largest (out of Clay, Silt, Sand, and Gravel)
