Information about Schist

Rocks are naturally occurring solids which are composed of minerals & have been used by humans since ages. From Stone Age, rocks are used for various purposes. Also, the metals and minerals found in rock play an important role in our life. Get to know all the Schist Uses. We have provided you with all information about Schist rock here. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. Schist is available in black, blue, brown, dark brown, green, grey, silver colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Schist is white.
