It is not only warm cream and honey toned limestones, such as the Cotswold limestones, that are appreciated for building, but also the crisp whiteness and light greys of limestones that are livened by subtle natural variations in shell content, grain size and

Carbonate Classification

Most limestones are classified by Folk allochemical Rocks if they contain over l0% allochems (transported carbonate grains). Based on the percentage of interstitial material, the Rocks may be further subdivided into two groups: sparry allochemical limestones (containing a sparry calcite cement of clear coarsely crystalline mosaic calcite crystals) and microcrystalline allochemical limestone ...

Grain size

Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks.The term may also be applied to other granular materials.This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. inside a particle or grain.

Limestone

 · Although limestones show little variability in mineral composition, they show great diversity in texture. [14] However, most limestone consists of sand-sized grains in a carbonate mud matrix. Because limestones are often of biological origin and are usually composed of sediment that is deposited close to where it formed, classification of limestone is usually based on its grain type and mud ...

Sedimentary rock

Sedimentary rock - Sedimentary rock - Grain size: Particle size is an important textural parameter of clastic rocks because it supplies information on the conditions of transportation, sorting, and deposition of the sediment and provides some clues to the history of events that occurred at the depositional site prior to final induration. Determining the sizes of the discrete particles that ...

Limestone

Limestone is defined by these two criteria: it is a sedimentary rock (1) and it is composed of calcium carbonate (2). There are other rocks that are composed of calcium carbonate. Carbonatite is a rare type of igneous rock and marble is a common metamorphic rock. is a common metamorphic rock.
