Grain size of siltstone
It is used to define loose granular particles falling in a specific size range. The silt particles have a diameter range between 0.00015 and 0.0025 inches. The silt in the siltstone doesn’t have a fixed composition. Its properties vary from place to place, but it is usually composed of micas, clay minerals, feldspars, and quartz. Siltstone ...Grain sizes are delineated using a logbase-2 scale [9; 10]. For example, the grain sizes in the pebble class are 2.52, 1.26, 0.63, 0.32, 0.16, and 0.08 inches, which correlate …

It means siltstone particles found in a suspension containing clay/mud, shell, and sand particles. Due to fine-size siltstone particles, the settlement demands quite still and calm water, as in lagoons, dep/big ponds, and puddles on the land.
This rock in the strict scientific usage is on the lower right corner with ash tuff (mean diameter of pyroclasts less than 1/16 mm which is analogous to siltstone).
