Aug 30, 2019 · by Jamey T. Sedimentary rocks are comprised of varying sizes of grains of rock or organic fragments which are called sediment. They are set apart into three different types of sedimentary rock; clastic, biogenic, and chemical. These types of sedimentary rocks are made different by the way they are formed and their composition. 6.2 Chemical Sedimentary Rocks Whereas clastic sedimentary rocks are dominated by components that have been transported as solid clasts (clay, silt, sand, etc.), chemical sedimentary rocks are dominated by …If non-clastic rocks are fine-grained enough, they too can be called aphanitic. Clastic sedimentary rocks are subdivided on the basis of grain size. Secondary characteristics used to further distinguish clastic rocks are sorting, grain shape, and grain composition. Grain size: Clastic sediments are distinguished on the basis of average grain size.Crystals begin to form if the ions present within a fluid, such as water, become very concentrated, either by the addition of more ions or the removal of water by freezing or evaporation. ... 4.3.1 Clastic Sedimentary Rocks.

An important characteristic of the clastic sedimentary rocks, however, is that all have clastic textures. That is, the grains are not interlocking- they are held together as an aggregate by a cement.

The clastic sediment is often referred to as “siliciclastic” because it is derived from the rocks of the crust which, as we have learned, is largely composed of silicate minerals of igneous rock. Clastic (or detrital) rock is classified and named based on the size and composition of the clasts. In contrast, the chemically-precipitated limestones consist solely of crystalline carbonates (e.g. microcrystalline limestone). The clastic limestones can be further subdivided according to their grainsize, much like other clastic sedimentary rocks. Other chemical sedimentary rocks. Other chemical sedimentary rocks include: banded-iron formations Clastic sedimentary rocks are dominated by components that have been transported as solid clasts (clay, silt, sand, etc.).
