Is chalk clastic.
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.

Calcite reacts vigorously with ...Chalk is a variety of limestone composed mainly of calcium carbonate derived from the shells of tiny marine animals known as foraminifera and from the calcareous remains of marine algae known as coccoliths. Chalk is usually white or light gray in color.

That's called ...Clastic Sedimentary Rocks . Clastic sediments are made of particles of mineral or rock fragments, known as clasts, that have been weathered from preexisting rock and transported by gravity, water, ice, or air.

Texture – non-clastic. Grain size – cryptocrystalline, cannot be seen except under very high magnification. Is sandstone a clastic organic or chemical? Sandstones are clastic in origin (as opposed to either organic, like chalk and coal, or chemical, like gypsum and jasper). The silicate sand grains from which they form are the ...Sedimentary rocks are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the ...
Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite. Calcite is an ionic salt called calcium carbonate or CaCO3. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite shells (coccoliths) shed from micro-organisms called coccolithophores. Flint (a type of chert) is very common as bands ... 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.Answers is the place to go to get the answers you need and to ask the questions you wantCommon sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash. Clastic Sedimentary Rocks:
Clastic sediment is the solid bits and pieces of rocks and minerals that have broken down from the source rock by a combination of physical and chemical weathering. Clastic sediment is sometimes called detrital sediment. Grains of clastic sediment range in size from microscopic (clay particles) to house size (large boulders), with sand and silt ...
Sedimentary rocks are formed by the lithification of inorganic and/or organic sediments, or as chemical precipitates.

In this context, four different chalk depositional systems are distinguished in the Chalk Group, with specific palaeogeography, depositional features and sediment composition. The first formalization of the lithostratigraphic subdivision of the Chalk Group in the Danish Central Graben is proposed, as well as an addition to the Cromer Knoll Group.

Noncarbonate chemical sedimentary rocks differ in many respects from carbonate sedimentary rocks and terrigenous clastic sedimentary rocks, and there is no single classification that has been universally accepted. This is a reflection of the great variation in mineral composition, texture, and other properties of these rock types. 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.Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering. Clastic rocks may also include chemically weathered sediment. Clastic rocks are classified by grain shape, grain size, and sorting. Chemical sedimentary rocks are precipitated from water saturated with dissolved minerals.
