There is some overlap between the two because almost ...
Other limestone that consists largely of the skeletal remains of marine organisms is considered bio-clastic, a cross between an organic and a detrital sedimentary rock. Typical detrital sedimentary rocks are those composed mostly of particles of pre-existing rock, although organic matter may be included; examples would be sandstone, shale, and …
Sedimentary rocks can be broadly classified into three main types based on their origin and characteristics: clastic, chemical, and organic sedimentary rocks. Clastic Sedimentary Rocks: Clastic rocks are formed from the accumulation and lithification of fragments of other rocks and minerals, known as clasts. These clasts are typically ... SEDIMENTARY ROCK TEXTURES. 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 ...

These are usually quartz and clay minerals, though collophane (cryptocrystalline apatite, a phosphate mineral) is also sometimes present, as nodules or as small pellets interpreted as fecal pellets. 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.Conglomerate Composition. Conglomerate is a type of sedimentary rock that is composed primarily of rounded or water-worn pebbles, cobbles, and boulders, which are known as clasts. These clasts are typically cemented together by a matrix of finer-grained sedimentary material, such as sand, silt, or clay.Chalk is an organically formed sedimentary rock.
