Sedimentary Rocks

Breccia is a rock shaped from angular gravel and boulder-sized clasts cemented collectively in a matrix. The angular nature of the clasts suggests that they have now not been transported very far from their source. There are numerous modes of formation for breccia. Some constitute consolidated material accumulated on steep hill slopes or on the foot of cliffs.

Siltstone is a clastic sedimentary rock that formed from grains whose sized between that of sandstone and mudstone. It can found different environmental conditions...

Chert is a microcrystalline or cryptocrystalline sedimentary rock cloth composed of silicon dioxide (SiO2). It takes place as nodules, concretionary hundreds, and as layered deposits. Chert breaks with a conchoidal fracture, often producing very sharp edges. Early people took advantage of the way chert breaks and used it to fashion cutting equipment and weapons. The name "flint" is also used for this fabric.

Mudstone is a really pleasant-grained sedimentary rock consisting of a aggregate of clay and silt-sized particles. Terms including claystone and siltstone are often used in location of mudstone, although these consult with rocks whose grain length falls inside a good deal narrower stages and underneath near exam those are frequently technically mudstones. Shale is frequently used to explain mudstones that are difficult and fissile (wreck along bedding planes). Marl is regularly used to explain carbonate-rich tender mudstones.

Greywacke is variation of sandstone that saperate from other to hardness, dark color, and poorly sorted angular grains of quartz and feldspar. Generally found in Palezoic strata. Generally larger grain can be sand clast. Matrix material more than 15%.

Marl or the other name Marlstone is a calcium carbonate non-clastic sedimentary rock. It has containt variable of clays and silt. The dominant carbonate...

Coal is a non-clastic sedimentary rock. They are the fossilized remains of plants and are in flammable black and brownish-black tones. Its main element...

An important rock-forming mineral, dolomite is named after the French mineralogist Déodat Gratet de Dolomieu. It is a colorless to white, pale brown, grayish, reddish, or pink mineral. Its crystals are commonly rhombohedral or tabular, often have curved faces, and sometimes cluster in saddle-shaped aggregates.

Bauxite is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminum-rich rocks in tropical...
