WebBreccia – 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. WebSedimentary rock is formed by sedimentation of material at the Earth’s surface and within bodies of water. Particles that form a sedimentary rock by accumulating are called sediment. Before being deposited, sediment was formed by weathering and erosion in a source area, and then transported to the place of deposition by water, wind, mass ...
