Schist vs Claystone


Definition

Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay   
Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation

Formation

Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of 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.

Claystone 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 Claystone and Schist Reserves. Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay. 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 Claystone vs Schist information and Claystone vs Schist characteristics in the upcoming sections.

Claystone vs Schist Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Claystone vs Schist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Schist. Learn more about Claystone vs Schist in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration. Due to some exceptional properties of Claystone and Schist, they have various applications in construction industry. The uses of Claystone in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Schist include As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone.

More about Claystone and Schist

Here you can know more about Claystone and Schist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Schist consists of mineral content and compound content. The mineral content of Claystone 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 Claystone vs Schist, the texture, color and appearance plays an important role in determining the type of rock. Claystone 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 Claystone is Rough and Dull and that of Schist is Layered and Shiny. Properties of rock is another aspect for Claystone vs Schist. Hardness of Claystone and Schist is 3.5-4. The types of Claystone are Not Available 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.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Schist is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Schist is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Schist is impact resistant, pressure resistant, water resistant.
