Uses of Sedimentary Rocks.sandstone (arenite) A type of sedimentary rock, formed of a lithified sand, and comprising grains between 63 μm and 1000 μm in size, bound together with a mud matrix and a mineral cement. Sandstone Any sedimentary rock composed of stony grains between 1/16 mm and 2 mm in diameter that are cemented together is a sandstone.Sandstone is a clastic sedimentary rock made from medium sized grains (1/4 to 2 mm). These grains are fragments of other rocks or minerals, bound together by cement. Depending on the variety of sandstone, the grains may range from poorly sorted to well sorted. Likewise, the grains may be rounded or angular.Many rocks are resistant to one kind of weathering and weak against the other. Limestone, for instance, is notably prone to chemical weathering given the solubility of its carbonate rock; in humid limestone provinces, caves and caverns – examples of karst landforms – abound. In arid country, by contrast, limestone can be quite resistant and ...Fun Facts about Sedimentary Rocks for Kids.
