It is soft, fine-grained and easily pulverized.According to Discovering Fossils, chalk occurs naturally in nature as calcium carbonate, a form of limestone. Limestone is formed from the decomposition and sedimentation of Coccolithophores skeletons, a type of plankton.Limestone origins. Limestone is a very common sedimentary rock consisting of more than 50% calcium carbonate. Although it occurs in many different forms, its origins can be traced back to either chemical or biochemical processes that occurred in the geological past, often tens to hundreds of millions of years ago.What type of sedimentary rock is chalk clastic chemical or organic? None of the above. Marble is a metamorphic rock.The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.Eating small amounts of chalk is usually not harmful, according to MedlinePlus. Chalk, a form of limestone, is not normally toxic, but when consumed in large quantities, problems can occur.An evaporite ( / ɪˈvæpəˌraɪt /) is a water- soluble sedimentary mineral deposit that results from concentration and crystallization by evaporation from an aqueous solution.

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. Is chalk clastic or non clastic?

Limestone is formed from the decomposition and sedimentation of Coccolithophores skeletons, a type of plankton.Despite chalk being a major hydrocarbon reservoir rock of the North Sea, surprisingly little is known about the physical behavior of the pelagic carbonate sediment from which the chalk formed—calcareous nannofossil ooze. This poses a serious challenge to the understanding of the depositional system and the properties of facies distribution.The minerals the clastic rock ends up containing will depend on how much “processing” the sediments undergo by physical and chemical weathering, and transport, before the sediment was cemented. On the other hand, chemical/biochemical sedimentary rocks are limited largely to those minerals that are highly soluble in water.Texture: Clastic, clay size, <1/256mm, laminated, often fissle ...

All of these “redeposited” limestones could be considered clastic sedimentary rocks, as well as organic sedimentary rocks. 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.Sedimentary Rocks. From the Latin sedimentum - settling. Sedimentary rocks make up only 5% (by volume) of the upper 10 miles of the crust, but about 75% of the outcrops on the continents.
