Chalk is a soft, porous, and white sedimentary rock. It is a form of limestone but is softer than limestone. The rock is not well cemented and is often brittle and powdery. You can easily break a small piece of chalk with your hand.Clastic Sedimentary Rocks. How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles.When the sediments harden, the layers are preserved. Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. As discussed in the “Earth’s Minerals” chapter, dissolved ions in fluids precipitate out of the fluid and settle out, just like the halite in figure 5.Clastic Sedimentary Rocks.

Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. As discussed in the “Earth’s Minerals” chapter, dissolved ions in fluids precipitate out of the fluid and settle out, just like the halite in Figure below. The evaporite, halite, on a cobble from the Dead Sea, Israel. These cementing substances come from the water that moves through the sediments. Sediments may also be hardened into rocks through compaction. This occurs when sediments are squeezed together by the weight of layers on top of them. Sedimentary rocks made of cemented, non-organic sediments are called clastic rocks.Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks.
