Detrital & Chemical Sedimentary Rocks: Definition & Differences Detrital or clastic sedimentary rocks are composed of rock fragments. They are different than chemical sedimentary rocks, which are composed of mineral crystals. Learn how these sedimentary rocks differ in their formation and composition.

- Clasts of rock are eroded from larger rocks, transported (moved) by wind or water and deposited in a basin.After some period of time, the clasts are lithified (lithos is the Greek word for stone). The sedimentary rocks we see today were once gravel, sand, silt, mud, or living things. We decide what to name sedimentary rocks based on the size of the clasts that make up the rock. For most sedimentary rocks, this is easy. Sandstone is made of sand, siltstone is made of silt, mudstone is made of mud and so on.

- Classification of Sedimentary Rocks by Origin. Detrital (or clastic) sedimentary rocks-Form from the cementation of sediment grains that come from pre-existing rocks. This is the most common sedimentary rock type. They are classified by grain size, and to a lesser extent by chemical composition.

- The most common clastic sedimentary rocks are breccia and conglomerate (formed from gravel), sandstone (from sand), siltstone (from silt), and shale (from clay). B. CHEMICAL SEDIMENTARY ROCKS. Chemical sedimentary rocks are crystalline, that is made of crystals interlocked with each other.ediment is a general term that indicates loose grains (such as the sand at the beach) and chemical precipitates (such as crystals of salt). Sedimentary rocks can be subdivided in three categories: clastic, chemical, and biochemical sedimentary rocks.

Sedimentary rock Sedimentary rock. Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral or organic particles (detritus) to settle in place.

Pictures of Sedimentary Rocks Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution. Organic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris.

Part IV. Weathering, soils, sediments, and sedimentary rocks (cont.) 1. Clastic (detrital): fragments of older rocks. 2. Chemical: precipitates from evaporated seawater. 3. Biochemical (bioclastic): fragments of skeletal matter. 4. Interpreting clastic sedimentary Rocks : a.

Sedimentary rock Clastic sedimentary rocks are composed of silicate minerals and rock fragments that were transported by moving fluids (as bed load, suspended load, or by sediment gravity flows) and were deposited when these fluids came to rest.

- Rockhound. The following are examples of sedimentary rocks: Types include clastic (cemented sediment particles), non-clastic (chemical precipitates or evaporites), and organic (from organisms, e.g. coal).Some will further divide sedimentary rocks into another type called bioclastic, rocks formed from clasts of organic matter (like sea shells).andstone, claystone, mudstone, conglomerate, and breccia are all examples of detrital sedimentary rocks-those composed of particles of pre-existing rock.

Pictures of Sedimentary Rocks It often forms as nodules in sedimentary rocks such as chalk and marine limestones. Dolomite (also known as dolostone and dolomite rock) is a chemical sedimentary rock that is very similar to limestone. It is thought to form when limestone or lime mud is modified by magnesium-rich ground water.rganic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris. Photos and brief descriptions of some common sedimentary rock types are shown on this page.

Clastic Sedimentary Rocks Finer‐grained rocks. The finer‐grained clastic sedimentary rocks are called shale, siltstone, and mudstone. Shale is a smooth, thinly layered rock that is made up of fine‐grained silt and clay particles. Shale is considered a fissile rock because it splits very naturally along its layers.

Sedimentary Rocks Lesson #13 Clastic sedimentary rocks are made of pieces of rock or mineral grains that have been broken from preexisting rock. These particles and grains have become solid rock by the processes of compaction or cementation of sediments. Some clastic rocks are conglomerate, shale, breccia, gray and red sandstone, siltstone, and graywacke.

Rocks Study Guide Sediments consist of: 1  Detritus: Detritus is fragmental material resulting from the break down of other rocks through the process of weathering. 2  Although we casually use the term erosion to refer to the breakdown of rocks, erosion is technically part of a series of processes that begins with weathering.etrital Rocks-these rocks have a clastic texture, that is they are composed of fragments compressed and cemented together. In detrital rocks, the clasts are fragments of detritus, the product of weathering of pre-existing rocks.

Organic Sedimentary Rocks Organic Sedimentary Rocks Organic sedimentary rocks form from the accumulation and lithification of organic debris, such as leaves, roots, and other plant or animal material. Rocks that were once swampy sediments or peat beds contain carbon and are black, soft, and fossiliferous.

LIthification of sediment into sedimentary rocks takes place after the sediment has been deposited and buried. The processes by which the sediment becomes lithified into a hard sedimentary rock is called diagenesis and includes all physical, chemical and biological processes that act on the sediment.

- Chemical sedimentary rocks are a different type of sedimentary rock because they are not made up of weathered sediment grains; instead they are composed of mineral crystals that form out of solution.In other words, chemical sedimentary rocks contain crystals and other elements that have been dissolved out of water.etrital or clastic sedimentary rocks are composed of rock fragments. They are different than chemical sedimentary rocks, which are composed of mineral crystals. Learn how these sedimentary rocks differ in their formation and composition.

- Sedimentary rocks fall into two broad categories, detrital rocks and chemical rocks. Detrital sedimentary rocks consist of cemented sediment grains that represent fragments of pre-existing rocks. Chemical rocks are deposited by the chemical process of precipitation from solution.Sedimentary rocks form in the following way: weathering of preexisting rocks creates rock fragments, clay minerals, iron oxides, and dissolved compounds in solution.edimentary rocks fall into two broad categories, detrital rocks and chemical rocks.

- Sedimentary rocks are formed on the earth's surface by the deposition and lithification of sediment. They comprise the weathered rind of the lithosphere. Because sediment is deposited incrementally over a surface, sedimentary rocks are layered and, unless deformed by some tectonic event, horizontal.. Detrital sedimentary rocks: These rocks are composed of mineral grains and/or rock fragments transported and deposited by some geologic agent. Detrital rocks are typically composed of mineral grains derived from silicate rocks.

- An introduction to SEDIMENTARY ROCKS Sedimentary rocks form from sediment. Sediment is a general term that indicates loose grains (such as the sand at the beach) and chemical precipitates (such as crystals of salt). Sedimentary rocks can be subdivided in three categories: clastic, chemical, and biochemical sedimentary rocks. a. clastic (or detrital) sedimentary rocks Clastic sedimentary rocks form when individual grains (the sediment), made by fragments of rocks, minerals, or shells, are cemented together (the clastic sediemntary rock).
