Mar 20, 2021 · Sedimentary rocks make up around 7.9 percent of the earth’s crust. Shales form 82 percent of this, while limestone makes up 6 percent. Sedimentary rocks usually have fossils. These rocks are created under the force of gravity. They are normally deposited next to horizontal layers or strata and this gives them the name ‘stratified rocks’.
Evaporite. Evaporites are rocks precipitated from saturated surface or near-surface brines by hydrologies driven by solar evaporation (e.g., Warren, 1999, 2006). From: Regional Geology and Tectonics: Phanerozoic Passive Margins, Cratonic Basins and Global Tectonic Maps, 2012. View all Topics.

Key Terms Cementation: The process by which clastic sediments become lithified or consolidated into hard, compact rocks, usually through deposition or precipitation of minerals in the spaces among the individual grains of the sediment.
Clastic sedimentary rocks are classified according to the grain size of the sediment and the kinds of rock fragments that make up the sediment (Table ). Grain size is largely a function of the distance the particle was transported. In general, the greater the distance traveled, the smaller and more rounded the sediment particles will be.Biochemical Sedimentary Rocks: Biochemical sedimentary rocks include rocks that are formed with the help of organic processes as well.

Chemical sedimentary rocks are classified based on their mineral content. Sedimentary rock textures. Sedimentary rocks are made of lithified sediment. The texture of a particular sedimentary rock results from how the sediment was formed, where it was deposited, and how it became rock. Sedimentary rock textures are different from igneous rock ...Detritus, or the rock and mineral particles that are moved by gravity, water, ice, or wind, forms the basis of detrital sedimentary formations. Grain size is used to classify detrital deposits. The size of the grain is used to categorize debris.
