[9] Although many naturally occurring deposits include both silts and clay, clays are distinguished from other fine-grained soils by differences in size and mineralogy. Thus, the particles which help in the formation of sedimentary rocks is known as sediment. Question 2: Give some examples of sedimentary rocks. Answer 2: Some of the most common sedimentary rocks are limestone, chalk, clay, sandstone and shale. These rocks cover around 75% of the total surface of the earth. Sedimentary rock - Clastic, Chemical, Organic: 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 are angular or subangular. Conglomerates are ...Grain Size. Detrital rock is classified according to sediment grain size, which is graded from large to small on the Wentworth scale (see figure).Grain size is the average diameter of sediment fragments in sediment or rock. Grain sizes are delineated using a logbase-2 scale [9; 10].For example, the grain sizes in the pebble class are 2.52, 1.26, 0.63, 0.32, …sedimentary rock, it is important to look at the grain size, grain roundness, and grain sorting. Grain Size Classification of clastic sedimentary rocks is based on the average diameter of constituent fragments. Grain size can be divided into four classes (Figure 5-2): (1) Coarse-grained (boulder-, cobble-, and pebble-sized) – larger than 2 mm. – A detrital (clastic) sedimentary rock made up of silt/clay sized particles (individual particles are indistinguishable). Forms in layers that are easily split. Click on image to see enlarged photo.Clay minerals and quartz are the primary minerals found in detrital sedimentary rocks.

Calcarenite – Type of limestone that is composed predominantly of sand-size grains. Chalk – Soft, white, porous sedimentary rock made of calcium carbonate. Chert – Hard, fine-grained sedimentary rock composed of cryptocrystalline silica. Clastic Sedimentary Rocks. How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles.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 ... Claystone, hardened clay. Some geologists further restrict the term to a sedimentary rock that is composed primarily of clay-sized particles (less than 1256 millimetre in diameter) and is not laminated or easily split into thin layers; such rocks that show cleavage roughly parallel to the beddingSedimentary rocks are the most abundant rock type exposed at the surface of the earth and cover about 99 percent of Kentucky. They were formed by the accumulation of rock fragments, shell fragments, plant material, muds, and sands, which were transported to their present locations by water, air, wind, or ice to form clays, sandstones, shales ...Those that form from organic remains are called bioclastic rocks, and sedimentary rocks formed by the hardening of chemical precipitates are called chemical sedimentary rocks.
