5.1 Formation
Novaculite forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The formation of Novaculite can be either of chemical or biological origin.
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Novaculite 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 Novaculite and Schist Reserves. Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture. 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 Novaculite vs Schist information and Novaculite vs Schist characteristics in the upcoming sections.

Novaculite 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. Novaculite vs Schist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Novaculite and Properties of Schist. Learn more about Novaculite vs Schist in the next section. The interior uses of Novaculite include Countertops, Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration. Due to some exceptional properties of Novaculite and Schist, they have various applications in construction industry. The uses of Novaculite in construction industry include Arrowheads, Building houses or walls, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Knives, Landscaping, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone, Spear points, Used to sharpen metal tools and weapons and that of Schist include As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone.

More about Novaculite and Schist

Here you can know more about Novaculite and Schist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Schist consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon 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 Novaculite vs Schist, the texture, color and appearance plays an important role in determining the type of rock. Novaculite is available in black, brown, green, grey, red, white colors whereas, Schist is available in black, blue, brown, dark brown, green, grey, silver colors. Appearance of Novaculite is Glassy or Pearly and that of Schist is Layered and Shiny. Properties of rock is another aspect for Novaculite vs Schist. The hardness of Novaculite is 7 and that of Schist is 3.5-4. The types of Novaculite 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 Novaculite is colorless while that of Schist is white.
