Sedimentary rocks contain information about what was occurring on earth’s surface at the place and time the sediments were deposited. In some cases sedimentary rocks contain fossils, which provide information about what was living at a certain place and time on earth. There are two main groups of sedimentary rocks: chemical and clastic.

Some of the fossils in limestone are too small to be seen without a microscope. Chalk is a type of5.4 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 components that have been transported as ions in solution (Na +, Ca 2+, HCO 3−, etc.). There is some overlap between the two because ...Chalk is a fine-grained limestone, usually formed by compacted microscopic animals called foraminifera. Chert is a fine-grained hard sedimentary rock composed of microscopic silica grains, and has a flat fracture. Flint is a variety of chert (mostly of upper Cretaceous age) that has a conchoidal fracture. Marl is a calcareous mudstone. Chalk, a sedimentary rock, is a soft form of limestone that is not well cemented and thus is often powdery and brittle.. What rocks are non-clastic? Non-clastic textures are found chiefly in rocks that have precipitated chemically from water (chemical sedimentary rocks), such as limestone, dolomite and chert.
Clastic sediments are broken down through mechanical means, like abrasion from wind, water or ice. They are what most people think of when mentioning sediment; things like sand, silt, and clay. Several physical properties are used to describe sediment, like shape (sphericity), roundness and grain size.

Sedimentary rocks are classified into three groups: Clastic, Biologic, and Chemical. Key Terms . Cementation: The process by which clastic sediments become lithified or consolidated into hard, compact rocks, usually through deposition or precipitation of minerals in the spaces among the individual grains of the sediment.Clastic sedimentary rocks are composed of grains, fragments of pre-existing rocks that have been packed together with spaces (pores) between grains. Non-clastic textures are found chiefly in rocks that have precipitated chemically from water (chemical sedimentary rocks), such as limestone, dolomite and chert.Chalk is a very fine‐grained bioclastic limestone composed of accumulations of skeletal debris from tiny marine organisms that drifted down to the ocean floor.

In clastic sediments the sedimentary texture includes the grain size, rounding, and sorting of the grains, all of which are related to what happened to the sediment during the weathering-to-deposition process.Because the processes that lead to the formation of chemical sedimentary rocks do not involve the weather-to-deposition process, there is no widely agreed-upon ...Oct 19, 2023 · These rocks are often called clastic sedimentary rocks.

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.Small-sized ferruginous micronodules or pisolith nodules, frequently occurring in inland freshwater systems in moderate climate zones, are important indicators of groundwater level changes and early diagenetic processes, especially within the Pleistocene post-glacial sedimentary systems, including swamps, peatbogs, rivers, or lakes.Oct 5, 2021 ...
