Sedimentary stone
Sandstone is a sedimentary rock made of grains of sand (defined as 1/16 mm to 2 mm sized particles) that have been naturally cemented together. Grains in sandstones are unfused, and some of these grains can be dislodged by rubbing across the rock. Sandstone represents ancient stream, deltaic, or beach deposits. Uses for sandstone include ...Concretions are commonly misunderstood geologic structures. Often mistaken for fossil eggs, turtle shells, or bones, they are actually not fossils at all but a common geologic phenomenon in almost all types of sedimentary rock, including sandstones, shales, siltstones, and limestones.

It varies in color, texture and hardness. Coquina is a poorly indurated form of shelly limestone. Shelly limestone is a sedimentary rock because it is made up of fragments.Following are the two types of igneous rock: Intrusive igneous rock: These rocks crystallise below the earth’s surface resulting in large crystals as the cooling takes place slowly. Diorite, granite, and pegmatite are examples of intrusive igneous rocks. Extrusive igneous rock: These rocks erupt onto the surface resulting in small crystals as ...
Breccia – Rock composed of broken fragments cemented by a matrix. Calcarenite – Type of limestone that is composed predominantly of sand-size grains. Chalk – Soft, white, porous sedimentary rock made of calcium carbonate. Chert – Hard, fine-grained sedimentary rock composed of cryptocrystalline silica.Other chemical sedimentary rocks include: banded-iron formations; ironstones; cherts; evaporites; silcretes; calcretes; Zebra rock. Zebra rock or Zebra stone is a distinctive reddish-brown and white banded claystone from the Ord River area of Western Australia where it forms discontinuous lenses within a Late Proterozoic shale sequence.Siltstone is a type of sedimentary rock composed of small, grain-sized particles, or silt.
