Siltstone is a sedimentary rock composed of cemented silt-sized particles of quartz and feldspar, primarily.
Siltstone is primarily composed of fine-grained particles ranging in size from 1/16 to 1/256 millimeter. These particles are mainly composed of quartz, feldspar, clay minerals, and other minerals like mica and calcite. Siltstone is formed through the consolidation of these particles deposited in low-energy environments such as lakes, lagoons, and deep ocean basins.
They are all clastic sedmimentary rocks formed mainly of silicate minerals.

Siltstone does not have many uses other than in soil. There are many particles of siltstone in soil and dirt. Siltstone can also be used in sculptures and buildings.
Silt is a mixture, not a pure substance. The density would depend on the mixture of minerals that make up the silt. Sand (quartz) has a density of about 2.5 g/cm3. If the silt is mostly sand then that would be a good approximation of the density.
Siltstone is mainly used as a building and construction material, such as in foundations, flooring, and walls. Its fine-grained composition and high strength make it suitable for these applications. Additionally, siltstone is used as a decorative stone in landscaping and sculpture.
Sedimentary
Siltstone is gritty to the touch. It has the texture of a very fine-grained sandpaper
Siltstone is a sedimentary rock composed of fine particles of silt-sized minerals and rock grains. It is formed through the lithification of sedimentary layers and does not contain organic material itself.
Siltstone can be formed from the eroded and transported particles of any rock type.
The density of siltstone typically ranges from 2.4 to 2.7 grams per cubic centimeter (g/cm³). This value can vary depending on the composition and porosity of the siltstone.
