• Clastic Sedimentary Rocks

    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 Textures and Classification of Clastic

    Clastic rocks form by the lithification of clastic material transported and deposited as solid clasts. Clastic rocks are classified and named according to texture (clast size, sorting and rounding), and mineral composition. An important characteristic of the clastic sedimentary rocks, however, is that all have clastic textures.

    Types of Sedimentary Rock ThoughtCo. 09-10-2019 Sedimentary rocks form at or near the Earth's surface. Rocks made from particles of eroded sediment are called clastic sedimentary rocks, those made from the remains of living things are called biogenic sedimentary rocks, and those that form by minerals precipitating out of solution are called evaporites.

    Sep 01, 2015· 6.1 Clastic Sedimentary Rocks A clast is a fragment of rock or mineral, ranging in size from less than a micron [1] (too small to see) to as big as an apartment block. Various types of clasts are shown in Figure 5.12 and in Exercise 5.3. The smaller ones tend to be composed of a single mineral crystal, and the larger ones are typically composed of pieces of rock.

    As rocks undergo weathering and erosion on the surface of the earth, they turn into grains of sediment. Clastic sediment is the solid bits and pieces of rocks and minerals that have broken down from the source rock by a combination of physical and chemical weathering. Clastic sediment is sometimes called detrital sediment.

Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing rock or organic material. There are three different types of sedimentary rocks: clastic, organic (biological), and

    Clastic sedimentary rocks form by weathering processes which break down rocks into pebble, sand, or clay particles by exposure to wind, , and water. Clastic and nonclastic sedimentary rocks are the only s of the rock family that contain fossils as well as indicators of the climate (ripple marks, mudcracks and raindrops) that was present when the rock was formed.
