Sedimentary rock | Paleontology Wiki | Fandom

Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in four main ways: by the deposition of the weathered remains of other rocks (known as ''clastic'' sedimentary rocks); by the accumulation and the consolidation of sediments; by the deposition of the results of biogenic activity; and by precipitation from solution. Sedimentary rocks ...

Sedimentary rock - Sedimentary rock - Texture: The texture of a sandstone is the sum of such attributes as the clay matrix, the size and sorting of the detrital grains, and the roundness of these particles. To evaluate this property, a scale of textural maturity that involved four textural stages was devised in 1951. These stages are described as follows. Immature sandstones contain a clay ...

Sedimentary processes

Sedimentary geologists (known as sedimentologists) tend to study both present-day sediments and older sedimentary rock sequences. Principle of uniformitarianism The principle of uniformitarianism is that processes which operate on the Earth''s surface today are similar to those that operated in the past.

Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg (CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar rocks.

Sedimentary rocks form on or near Earth''s surface. Eroded particles of rock are transported by wind, water, and ice and deposited on dry land, on the beds of rivers and lakes, or in the seas. Over years, these pieces of rock, or sediments, are pressed together by the weight of new deposits on top of them and cement together to form rocks.
