Information about Peridotite

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 Peridotite Uses. We have provided you with all information about Peridotite rock here. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. Peridotite is available in dark greenish - grey colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite is white.
