Deposited Silt and Desert Dunes
deflate
Wind erosion can form features such as sand dunes, loess deposits, and desert pavement. Sand dunes are created by the deposition of sand grains carried by the wind, while loess deposits consist of fine silt particles that settle out of the wind. Desert pavement forms when finer particles are removed by the wind, leaving behind a surface of coarser rocks and pebbles.
A "dune field" is an area covered by extensive sand dunes. ... Dunes also form under the action of water flow

Deflation of sand and silt from the surface
Silt does not have a taste as it is a fine sediment composed of particles of sand, clay, and organic matter. However, ingesting silt can be harmful to health as it may contain contaminants and pathogens.
IS limit for silt in sand is 15to 35
Yes, silt is smaller than sand.
Continued high winds will pick up dust and silt particles and blow clouds of them cross-country until the wind dies down and the dust and silt fall to earth. Sometimes, especially where I live in North Idaho, the loess (luss) was formed into what look like sand dunes. Dust dunes, I guess.
Soil can contain a variety of rock materials, such as sand, silt, and clay particles derived from the weathering and erosion of rocks. It may also contain larger rock fragments and minerals like quartz, feldspar, and mica that have been broken down over time. The specific rock materials in soil will depend on the parent rock type in the area and the processes of weathering and erosion that have occurred.
