Sedimentary Rock. The sedimentary rocks are formed by the deposition and subsequent cementation of that material within bodies of water and at the surface of the earth. The process that causes various organic materials and minerals to settle in a place is termed as sedimentation. The particles that form a sedimentary rock by accumulating are called sediment. Before being deposited, the ...

Sedimentary rocks are the most common rock types which are freely exposed on the earths surface. They are formed from other rock materials since they are made up from the buildup of weathered and eroded pre-existing rocks.

Nov 23, 2020 Sedimentary rocks are classified into three groups Clastic, Biologic, and Chemical. 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.
Sedimentary Rocks And The Rock Cycle
Sedimentary rocks are formed by the lithification of inorganic andor organic sediments, or as chemical precipitates. There are two types of sedimentary rocks Clastic and Chemical Clastic sedimentary rocks form when existing parent rock material is weathered, fragmented, transported, and deposited in layers that compact,

and history of clastic sedimentary rocks. As with igneous rocks, a complete description and classification must be based on both mineral content and texture. The relative abundance of mineralogical and non-mineralogical constituents in clastic rocks is determined largely by the nature of the source of the sedimentary material and the type of
Clastic Sedimentary Rocks Cliffsnotes
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.

Sedimentary rocks are classic clastic rocks. Other types of rock can be clastic as well. Igneous rocks, which form as a result of volcanic activity, may take the form of clastic rocks. Tuff, for example, is an igneous rock which is actually comprised of a number of fragments, making it both igneous and clastic in nature.

Top 7 Differences Between Sedimentary Rocks And Igneous Rocks
Most sedimentary rocks contain either quartz especially siliciclastic rocks or calcite especially carbonate rocks. In contrast with igneous and metamorphic rocks, a sedimentary rocks usually contains very few different major minerals. However, the origin of the minerals in a sedimentary rock is often more complex than those in an igneous rock.
