Siltstone, also known as aleurolite, is a clastic sedimentary rock composed mostly of silt, a form of mudrock with low clay mineral content distinguished from shale by its lack of fissility. It represents consolidated fine sediment that settled out of air or water in relatively quiet depositional environments.

Ukhaa Tolgod (also spelled Oka Tolga): The strata exposed at Ukhaa Tolgod is dominated by reddish sandstones, with some sandstones containing small amounts of conglomeratic lenses and/or cobbles and pebbles. Conglomerate itself is in this site, and to a lesser level are mudstones and siltstones, which are thin and laterally restricted.
