Sandstone is a sedimentary rock composed of sand-size grains of mineral, rock, or organic material. It also contains a cementing material that binds the sand grains together and may contain a matrix of silt- or clay-size particles that occupy the spaces between the sand grains.

The imprint of the environment is recorded as the relative abundance and size of individual detrital species. Differences between environments within any one basin are accompanied by concomitant changes in detrital-sediment composition.Note in Table 2 that there are several densities reported for the same mineral group, such as feldspar or clay. The density will change systematically as composition varies. For example, in the plagioclase series, the density increases as sodium (albite, ρ = 2.61 g/cm 3) is replaced by calcium (anorthite, ρ = 2.75 g/cm 3).The most problematic …Detrital framework modes of sandstone suites from different kinds of basins are a function of provenance types governed by plate tectonics.

Diatomite is a sedimentary rock with many uses. It is made up of the siliceous skeletal remains of diatoms, which are tiny single-celled algae. Diatomite is crushed into a powder known as "diatomaceous earth". It is lightweight, porous, relatively inert, and has a small particle size along with a large surface area. Several schemes were proposed and debated; few were accepted. One of the central topics of discussion was the relative importance of sandstone texture versus sandstone composition. A classification based on texture alone was deemed inadequate; if the rock or sediment had >50% sand, then it was a sandstone, or arenite.

It has a glorious banding which is apparent on microscopic scale and hand specimen. It usually is prominent from schist by its …Sedimentary rock - Clastic, Chemical, Organic: The texture of a sandstone is the sum of such attributes as the clay matrix, the size and sorting of the detrital grains, and the roundness of these particles. To evaluate this property, a scale of textural maturity that involved four textural stages was devised in 1951. These stages are described as follows.
