Poorly sorted rock
Webwacke, also called dirty sandstone, sedimentary rock composed of sand-sized grains (0.063–2 mm [0.0025–0.078 inch]) with a fine-grained clay matrix. The sand-sized grains are frequently composed of rock fragments of wide-ranging mineralogies (e.g., those consisting of pyroxenes, amphiboles, feldspars, and quartz). The grains are angular and poorly … WebRock debris that has been moved and deposited by physical movement is referred to as lithification. Abrasion or sorting can cause the rock particles to become rounded or highly sorted during transportation. A clast is a piece of a rock or mineral turned into small pieces by weathering and erosion the parent rock.

WebConglomerate (/ k ən ˈ ɡ l ɒ m ər ɪ t /) is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts.A conglomerate typically contains a matrix of finer-grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts. The clasts and matrix are typically cemented by calcium … WebSorting - a conglomerate comprising a mixture of clast sizes is poorly sorted, while one comprising mostly clasts of the same size is well sorted; Lithology - a conglomerate where the clasts represent more than one rock …

WebSorting. Sorting is the variability in grain size in a clastic sedimentary rock. This parameter measures how well a sediment has been ‘sorted’ by the process that transported it. A … WebJun 8, 2024 · Figure \(\PageIndex{1}\): Well-sorted sediment (left) and Poorly-sorted sediment (right). When reading the story told by rocks, geologists use sorting to interpret erosion or transport processes, as well as deposition energy. For example, wind-blown sands are typically extremely well sorted, while glacial deposits are typically poorly sorted.
WebSedimentary rock types Conglomerates and breccias. Conglomerates and breccias are sedimentary rocks composed of coarse fragments of preexisting rocks held together either by cement or by a finer-grained clastic matrix.Both contain significant amounts (at least 10 percent) of coarser-than-sand-size clasts. Breccias are consolidated rubble; their clasts …
WebSome rocks will be made up of grains that are all the same size (or very close), while others will have a variety of grain sizes. In sedimentary rocks, we refer to uniform grain sizes as ‘well-sorted’ while rocks with a variety of grain sizes are referred to as ‘poorly-sorted’.
