  2. Sedimentary rock - Wikipedia

    en.wikipedia.org/wiki/Sedimentary_rock

    Sedimentary rocks are often deposited in large structures called sedimentary basins. Sedimentary rocks have also been found on Mars. The study of sedimentary rocks and rock strata provides information about the subsurface that is useful for civil engineering, for example in the construction of roads, houses, tunnels, canals or

  3. List of rock types - Wikipedia

    en.wikipedia.org/wiki/List_of_rock_types

    Coal – Combustible sedimentary rock composed primarily of carbon; Conglomerate – Sedimentary rock composed of smaller rock fragments; Coquina – Sedimentary rock that is composed mostly of fragments of shells; Diamictite – Type of sedimentary rock; Diatomite – Soft, siliceous sedimentary rock that is easily crumbled

  4. Clastic rock - Wikipedia

    en.wikipedia.org/wiki/Clastic_rock

    Clastic sediments or sedimentary rocks are classified based on grain size, clast and cementing material composition, and texture. The classification factors are often useful in determining a sample's environment of deposition. An example of clastic environment would be a river system in which the full range of grains being transported by the ...

  5. Sedimentology - Wikipedia

    en.wikipedia.org/wiki/Sedimentology

    Art: marble, although a metamorphosed limestone, is an example of the use of sedimentary rocks in the pursuit of aesthetics and art Architectural uses: stone derived from sedimentary rocks is used for dimension stone and in architecture , notably slate (metamorphosed shale ) for roofing , sandstone for load-bearing buttresses

  6. Conglomerate (geology) - Wikipedia

    en.wikipedia.org/wiki/Conglomerate_(geology)

    Conglomerate (/ k ən ˈ ɡ l ɒ m ər ɪ t /) is a sedimentary rock made up of rounded gravel-sized pieces of rock surrounded by finer-grained sediments (such as sand, silt, or clay). The larger fragments within conglomerate are called clasts, while the finer sediment surrounding the clasts is called the matrix.

  7. Sedimentary structures - Wikipedia

    en.wikipedia.org/wiki/Sedimentary_structures

    Sedimentary structures include all kinds of features in sediments and sedimentary rocks, formed at the time of deposition. Sediments and sedimentary rocks are characterized by bedding , which occurs when layers of sediment, with different particle sizes are deposited on top of each other. [ 1 ]

  8. Rock (geology) - Wikipedia

    en.wikipedia.org/wiki/Rock_(geology)

    Metamorphic rocks are formed by subjecting any rock type—sedimentary rock, igneous rock or another older metamorphic rock—to different temperature and pressure conditions than those in which the original rock was formed. This process is called metamorphism, meaning to "change in form". The result is a profound change in physical properties ...

  9. Organic-rich sedimentary rocks - Wikipedia

    en.wikipedia.org/wiki/Organic-rich_sedimentary_rocks

    Organic-rich sedimentary rocks may act as source rocks which generate hydrocarbons that accumulate in other sedimentary "reservoir" rocks [2] (see oil sands and petroleum geology). Potential source rocks are any type of sedimentary rock that the ability to dispel available carbon from within it (limestone is a classic example of a source rock ...
