Chert: Sedimentary Rock

Chert is a sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2 ). It occurs as nodules, concretionary masses, and as layered deposits. Chert breaks with a conchoidal fracture, often producing very sharp edges. Early people took advantage of how chert breaks and used it to fashion ...

The infrared optical constants of limestone particles and ...

Abstract Theoretical studies and numerical models of the atmosphere and surface of Mars need the knowledge of the optical constants of candidate materials for Martian dust. Limestone, as a carbonate bearing material, is commonly considered a likely component particularly important for its links with the climate evolution and water resources on Mars.

Particle-size distribution

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.

Chert Rock | Types, Properties, Composition, Formation, Uses

Chert occurs in carbonate rocks that are greensand, limestone, chalk, and dolostone formations as exchange mineral, where it is formed as a result of some type of diagenesis. if where it occurs in chalk or marl, it is called flint. It also occurs in thin beds, when it is a primary deposit (such as with many jaspers and radiolarites).

Sorting. The extent to which all the grains are the same size is known as sorting. If all the grains are the same size, they are well sorted. Some sandstones are well sorted, and some are not. Most conglomerates are poorly sorted, and consist of a mixture of grain sizes ranging from sand to pebble.
