Characteristics of Schist
Many rocks have distinct characteristics. Some of the Properties of Schist are hardness, structure, streak, fracture etc. Schist is significant as it is composed of minerals and has variety of uses in our day to day life. The characteristics of Schist plays an important role in its identification.
The hardness of Schist is 3.5-4 on Moh’s hardness scale. Rocks according to their hardness are divided into:Hard Rocks, Soft Rocks and Rocks with Medium Hardness.
Fracture of Schist rock is conchoidal. Its specific heat capacity is Not Available. Schist is impact resistant, pressure resistant, water resistant. Some of its uses are:
- Interior Uses: Decorative aggregates, Floor tiles and Interior decoration.
- Construction Industry: As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone.

More About Schist
Schist is a type of Metamorphic Rocks. The color of rock is one of its important property. Schist rock is available in black, blue, brown, dark brown, green, grey, silver colors. It is Layered and Shiny in appearance. The Schist mineral content includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc. Its compound content includes CaO, Carbon Dioxide, MgO. Let’s move on to the types of Schist. The types of Schist include Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist..
Fossils are the remains of prehistoric plants or animals which are embedded in rock and preserved in petrified form. Fossils are found only in sedimentary rocks. As Schist belongs to Metamorphic Rocks, fossils are not found in it.
