Is chalk clastic.

A chalk is a soft, friable variety of limestone consisting of poorly lithified calcareous ooze, produced by the accumulation of planktonic organisms in a pelagic (open sea) environment. Chalk is largely made of shells of single-celled marine organisms, such as foraminifera and coccoliths, but fragments of shells of bivalves and ostracods might ... Chalk is a type of limestone made up of the microscopic calcium carbonate shells of marine organisms.

Chalk is opaque in …Type Sedimentary Rock Origin Biochemical Texture Clastic Composition Calcite Color Tan Miscellaneous Poorly cemented shell fragments; Reacts with HCl; Hardness < Glass Depositional Environment BeachChalk is typically almost pure calcite, CaCO3, with just 2% to 4% of other minerals. 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.

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.

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.We would like to show you a description here but the site won’t allow us.
