5 Formation

5.1 Formation

Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Mudstone vs Schist Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Mudstone and Schist Reserves. Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Mudstone vs Schist information and Mudstone vs Schist characteristics in the upcoming sections.

More about Mudstone and Schist

Here you can know more about Mudstone and Schist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Schist consists of mineral content and compound content. The mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Schist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Schist, the texture, color and appearance plays an important role in determining the type of rock. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Schist is available in black, blue, brown, dark brown, green, grey, silver colors. Appearance of Mudstone is Rough and Dull and that of Schist is Layered and Shiny. Properties of rock is another aspect for Mudstone vs Schist. The hardness of Mudstone is 2-3 and that of Schist is 3.5-4. The types of Mudstone are Marl, Shale and Argillite whereas types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist..
